Steinernema carpocapsae production underway at Dudutech’s biorational labs

Posted by

S. carpocapsae is a powerful novel entomopathogenic nematode already in use in Europe and the US, and our production capabilities have helped create additional availability.

Cutworms (Agrotis spp.) and leatherjackets (Tipula spp.) are larval stage pests that damage vegetable, cereal and root crops by biting and feeding on the plant stems and leaves. To combat these pests, Dudutech has begun production and R&D of Steinernema carpocapsae a deadly pest-parasitic nematode that targets Agrotis spp. and Tipula spp. to complete their lifecycle.

Catherine Gacheri prepares for a new role as Regional Technical Manager 

Posted by

As Catherine Gacheri prepares for her new role as “Regional Technical Manager”, we reflect on her history in IPM at Dudutech.


During her 21 year tenure at Dudutech, Catherine Gacheri has blazed a trail for IPM in Kenya and now Africa. Having worked in every part of Dudutech, Catherine is uniquely positioned – with a deep understanding of every step of the IPM product journey from R&D to in-field technical support. In 2022, Catherine will also take up an exciting new role as Regional Technical Manager. 

As Dudutech expands further into new markets, the new position was created to provide customers with enhanced technical support and new product development. Catherine said, “the position offers an opportunity for career and personal growth.” As Regional Technical Manager, Catherine will also work closely with R&D, marketing and training to help farmers access information and advice. 


Catherine’s track record as an IPM champion 

Catherine joined Dudutech as a Field Trials Officer in 2001 after graduating from University of Nairobi with an BSc in Agriculture, although her first experience with biologicals came from ICRISAT (International Crops Research Institute for the Semi-Arid Tropics) where she worked with natural enemies for pest control. Starting with a research role, Catherine conducted some of Africa’s earliest field trials using these biotech solutions.  

In one story Catherine told in an interview, she recalled isolating a natural enemy for aphids from her mother’s garden. In another, she spoke about her contribution to academia through her paper on what is now known as hotspot treatment that led to a new strategy that reduces the cost of natural enemy applications. (Read about the research here).

By 2002, Catherine’s role evolved into production management for the outdoor insectaries. This experience provided insight into how the mites and parasitoids behave and what makes them thrive. It also primed Catherine for the next 16 years of her career providing technical support to internal, external and international growers across Africa. 

According to Catherine, the early to mid-2000s was an adoption phase for the IPM industry. “At that time, biological pest controls were a new concept to growers in Kenya. There was little information available,” she recalled. “The landscape was very much chemical focussed so we had to prove that it works.” 

This challenge allowed Catherine the opportunity to develop close long-term relationships with the growers and share knowledge about IPM. “Despite the early hurdles, the farmers quickly realised the value of using biologicals and widespread adoption began among the commercial/export farmers,” Catherine commented. 

As exportation began to Zimbabwe and South Africa, Catherine’s deep expertise was leveraged in the new markets and her role officially became “Field Technical Support East & Southern Africa.” Using the experiences gained in Kenya, Catherine was equipped to help growers transition to IPM. Her work in the region helped cement Dudutech’s position as a leading IPM supplier in Africa. 

After 7 years in this role, she was promoted to Kenya Technical Sales Manager, bringing her closer to her family. Her existing experience and decades-long relationships with Kenyan growers meant Catherine was the best choice to drive sales in Kenya. 

During her career, Catherine has invested in personal development and continued her education, attaining a MSc in Agricultural Entomology and a PG Cert. in sales and marketing from the University of Cape Town.

Forging strong relationships
In mid-January 2022, Dudutech hosted Phil Weller from Dudutech Zimbabwe and his customers, Chris and Ferdinand from Forrester Estate for a tour of Ladybird Farm in Naivasha, Kenya.

The trip aimed to provide a deeper understanding of the products and capabilities directly to the farmers. The group took part in a special guided backstage tour of Dudutech’s state-of-the-art facility including the outdoor and indoor insectaries, fungal and nematode production and quality control facilities.

Phil has been working with the Forrester Estate team for over 6 years to deliver sustainable crop protection to their 2,300 Ha of crops including peas, tobacco, blueberries, cereals, grasses and citrus.

“Our Dudutech trip was an eye-opener,” said Ferdinand (Forrester Estate), “it is truly amazing what growth the Dudutech team achieved with their vision, driven research and bold management. Ecological sustainability is the foundation of economic sustainability… There is much more we need to do: IPM, compost, worm farming, activated charcoal, green manure and crop rotation.”

Festus brings considerable experience to his new role having spent 3 years in Ethiopia serving Sher Afriflora, the world’s biggest flower farm, after working in IPM for cut flowers and vegetables in Kenya. 

He will regularly visit Tanzania and Uganda to ensure continuous engagement with growers, whose main focus areas are cut flowers, avocados, and macadamias. Commenting on pests and diseases, Festus said, “Avocado’s major challenges in Tanzania are: Phytophthora root-rot, Damping-off disease, False codling moth (FCM), Fruitflies, Vine weevils. Major pests for cut flowers in the area are Thrips and spider mites.” 

To help tackle these challenges, Dudutech has registered a range of products in each country. Looking at the novel challenges, Festus said, “we are making every possible effort to ensure more products are registered in these regions for a wider range of solutions to the growers.” 


  • PHYTOTECH – predatory mites for RSM 
  • BEAUVITECH – Insect-killing fungi for Thrips and Whiteflies 
  • MYTECH – Nematode-killing fungi for Plant Parasitic Nematodes 
  • LECATECH – Insect-killing fungi for Thrips and Whiteflies 
  • TRICHOTECH – Beneficial soil fungus for soil health 


  • PHYTOTECH – predatory mites for RSM
  • MYTECH – Nematode-killing fungi for Plant Parasitic Nematodes 
  • TRICHOTECH – Beneficial soil fungus for soil health

According to Festus, “there is no doubt IPM is the future in farming, the growers are eager to know which solutions we can offer in a cost-effective and sustainable way.” He went on to say, the agricultural landscape in Tanzania and Uganda are very similar to Kenya, with growers open to new technologies.”

Dudutech team members registering the first shot of their COVID-19 vaccination.

As a part of our ongoing commitment to our team’s health and safety and joining the global drive to eliminate COVID-19, Dudutech is rolling out a vaccination program to the entire team. According to Benjamin Desruelle, Dudutech’s COO, the program which started on 16 April 2021 is “targeting a 100% vaccination rate for the first shot in December 2021.”

Wilson Wainaina, Dudutech’s HR manager, said “we have a reduced risk of our employees getting infected with Covid -19. As vaccination rates rise within the company, it is less likely people are to experience stress or skip health care appointments – which means happier and more productive employees.”

The vaccination program is aimed at helping further protect the health and wellbeing of our team. By working closely with all departments, the program has so far reached 85% of team members with the first dose, totalling 302.

The welfare committee was used to raise awareness by engaging directly with the participants. Although, Wilson said “religious beliefs and underlying medical conditions” were major challenges to the program.

Building knowledge and understanding through QC training

Earlier this year, Constance Muholo, Dudutech Macrobial QC Manager, and the quality team from Dudutech went to Sher Afriflora’s 490Ha rose farm located at Ziway, Ethiopia to set up a QC bench at their facility. The project aimed at building customer-side knowledge and understanding, and provides end-to-end QC protocols and a team of trained technicians familiar with the process. This enables Sher to assess the condition of the mites they receive rapidly and confidently.

The effect of establishing the QC bench was almost immediately realised. The team were better able to correctly distinguish the mites within the bottles and so raised fewer queries. John Ogechah, Export Manager, said, “feedback from the customer has been positive so far.”



Phil Weller Nominated to sit on Biopesticide Advisory Board

Posted by

Phil Weller from Dudutech Zimbabwe has been nominated to represent the private sector on the Biopesticides Project Advisory Board by the International Centre for Genetic Engineering and Biotechnology (ICGEB).

The board is made up of experts from the industry, research and academia, regulators and farmer bodies, and will collaborate and consult on “Enhancing Trade Through Regulatory Harmonisation and Biopesticide Based Residue Mitigation in the SADC Region.” As the name implies, the project seeks to improve the agricultural trade position for the block (which includes Tanzania, DRC, Mozambique, Malawi, Angola, Zambia, Zimbabwe, Botswana, South Africa, eSwatini – formerly Swaziland – and Lesotho) by reducing pesticide residue levels through the adoption of biocontrols in agriculture.

Many major horticulture importing markets, such as the EU and US, have strict MRL (Maximum Residue Limit) regulations on the acceptable levels of pesticide residue on imported food and flowers. Globally, growers who wish to enter these markets often adopt IPM and biocontrols from Dudutech in their pest management programmes to work around MRL restrictions.

On being nominated, Phil said, “it is a great honour to be asked to play a part in such an important project.” With a member of the Dudutech team representing the private sector, we have a unique opportunity to help growers adopt IPM and mitigate residues on their farms.

Graph: Value Added Agriculture for SADC in US$.

According to World Bank data, since 2000, the combined value-added agriculture in the SADC region has more than doubled, from US$18 billion to around US$45 billion. Although production capabilities are in place, accessing high-value markets is a key to transforming the value of ag produce exported. By looking to other African countries which have had some success in enhancing their trade partly through the use of biologicals, such as Kenya, growers are able to see the value in adopting this new technology. For example, the same World Bank data for Kenya shows this metric balloon 10 times over from 2000 to 2020, reaching US$34.7 billion, nearly three-quarters of the value-added agriculture for the entire SADC region.

Trichotech WP now approved in Ethiopia

Posted by

Dudutech’s Ethiopia team are excited to announce that TRICHOTECH WP has been approved for importation and use in Ethiopia, giving growers a powerful new tool for preventing diseases caused by Fusarium spp. and promoting good soil health. Our team have been working closely with local authorities to bring TRICHOTECH WP to market for Ethiopian growers.

TRICHOTECH WP has been an integral part of Dudutech’s IPM portfolio since 2002 and is helping farmers in Africa (Kenya, Tanzania, Zimbabwe, South Africa and now Ethiopia, with more on the way) combat plant disease without harming beneficial organisms, farmworkers or the environment.

TRICHOTECH WP mode of action.

T. asperellum is a powerful naturally occurring beneficial soil fungus used to manage diseases caused by Fusarium spp. and to promote plant growth. Each gram of TRICHOTECH WP contains 4 billion Trichoderma asperellum spores or Colony Forming Units (CFUs) mixed in an inert carrier. Once drenched on the crop, the spores germinate and the fungus grows, defending the roots and releasing nutrients locked in undecayed organic matter. By using TRICHOTECH WP, growers can sustainably manage crop disease, improve soil health and improve the health and vigour of the plant while using fewer chemicals.

Advantages of TRICHOTECH WP:

  • Protects and promotes good soil health
  • No resistance development
  • No harmful residues
  • No MRLs
  • 0 PHI and 0 REI

A look into how we use our Packing and Logistics Centre to drive quality for our customers.

By Cory Smit, Dudutech Marketing

Rearing biologicals is one thing – getting them around the world, alive and ready to feast, is a whole other challenge. In recent years, a significant amount of R&D focus at Dudutech has been on understanding this challenge and meeting it through innovations in quality control, cold-chain management and packaging specs. The result is consistent delivery anywhere in the world within 48 hours, without compromising the performance of the biologicals.

At Dudutech, it all starts with the people. Over 350 employees have been trained and integrated into the Dudutech family, among them doctoral and post-grad scientists, each with their own place and purpose. The team leans on their extensive collective experience to guarantee optimum product quality at every stage, from R&D to delivery on the crop.

Following harvest, Jack Adundo – Technical Manager – and his dedicated QC (Quality Control) scientists vigorously check each batch on a microscopic level. By building the ISO 9001:2015 Quality Management System into our tried and tested Standard Operating Procedures, we ensure only products of the highest degree of quality make it to the customer’s crops. These safeguards are further buffered by pre-pack and after-pack sampling of each batch to aid quick troubleshooting and provide feedback into our continuous improvement program.

From there, their journey around the world begins. Eric Langat, who is at the head of the team at the Packhouse and Logistics Centre, fulfils the orders and uses a dynamic logistics network to secure the earliest possible delivery times.

Each of the packaging standards is continuously trialled and the resulting innovations have had a significant impact on how we pack and move the orders. The most important recent improvements are the packaging re-use scheme, the volume each order occupies, maintenance of conditions in transit, improved ease of use and optimised performance on delivery. 

In particular, the packing standards for our mites range combine an improved bottle shape and bespoke Duduvent cap design with streamlined shipping materials to balance performance, efficiency and size in transit. Duduvent provides a unique solution to the challenge. It ensures the air inside the mite’s bottles is cool and fresh and provides end-users with a better way to spread the mites on the crop.

While the tickets are being booked, each order enters our bio-chain. This specially designed and digitally monitored cold-chain system can maintain transit conditions over great distances for up to 48 hours.

Image: A bio-chain delivery vehicle used to transport biologicals under climate-controlled conditions. (Dudutech, 2020).

Our fleet of custom-designed delivery vehicles forms the backbone of our bio-chain network. These refrigerated trucks are used to distribute the orders from our Ladybird Farm in Naivasha directly to farmers in Kenya or to export customers via Jomo Kenyatta International Airport.

We include digital data monitors in each shipment to gather data on humidity and temperature and this information is then carefully analysed and relayed back to the technical team for further improvement.

Beauveria bassiana: What about the bees?

The effect of Beauvitech on nature’s little helpers

By John Ogechah and Cory Smit


Beauveria bassiana is a well-known soil-dwelling entomopathogenic (insect-killing) fungus found all over the world. For more than 100 years, tons of B. bassiana spores (e.g. Beauvitech®) have been commercially produced and used for biological control of insect pests worldwide. Growers have come to rely on this clever biological action known as white muscardine disease as a major player in chemical-free pest control. 

Following increased interest in biocontrol of pest insects between 1980 and 1990, safety aspects were raised and discussed in great detail. Burges (1981) outlined the main principles and guidelines for testing the safety of insect pathogens and “that a pathogen should be registered as safe when there is reasonable evidence that it is so and in the absence of concrete evidence that it is not. A “no risk” situation does not exist, certainly not with chemical pesticides, and even with biological agents one cannot absolutely prove a negative.” 

The commercial use of entomopathogenic fungi and their products as mycoinsecticides (fungus-based insecticides), therefore, necessitates their registration based on certain safety guidelines. Beauveria bassiana is indeed registered in several countries and proof of safety to non-target organisms such as mammals, fish, amphibia, birds, pollinators etc is an important requirement before registration.

Still, the lingering question posed by farmers and indeed the greater society is “What about the bees?” In other words, how safe are mycoinsecticides and, specifically, Beauveria bassiana to these little helpers of nature?

There are numerous peer-reviewed papers on the effect of B. bassiana on honeybees and other beneficial organisms. Examples are presented in Table I below. Notable is the fact that most of the studies were done in the laboratory and only a few in the field. 

The vast majority of the studies done on bees conclude that despite the wide host range of B. bassiana, this fungus can be used with minimal impact on honeybees and other non-target organisms. Some experiments showed that B. Bassiana can be blown directly into hives to manage Varroa destructor mites (Acari: Varroidae) without a negative effect on the bee colonies (Miekle et al., 2008; Rodríguez et al. 2009). Another set of experiments looked at using honeybees to distribute B. bassiana spores directly to crop flowers and foliage (Almazra’awi et al. 2006). Similarly, no adverse effects on the bees were reported. 

In one case, however, Almazra’awi (2007) reports that B. bassiana strains caused high mortality in caged bees dusted with dry formulations of high concentrations (10⁸-10 CFUg-1). Interestingly, in the same paper (Almazra’awi, 2007), exposure of whole beehives under field conditions resulted in low mortality that was not different from the controls regardless of the isolate tested. This points to the difference between the physiological host range and the ecological host range (Hajek & Butler 2000). 

The physiological host range demonstrates the range of insect species that can be infected in the laboratory, while the ecological host range demonstrates which insects can be infected in nature or under field conditions. Non-target insects which are infected under laboratory conditions, may not necessarily be infected in nature (Zimmermann, 2007)

We conclude that despite the wide host range of B. bassiana, evidence to date suggests that this fungus can be used with minimal impact on non-target organisms, especially when isolate selection and spacio-temporal factors are taken into consideration. Our answer is unwavering: Beauveria bassiana (Beauvitech®) has no negative effect on honeybees (Apis mellifera) in normal field conditions. In fact, there are numerous examples of benefits B. bassiana can have with and for bees.

TreeTech 2019 a success

Posted by

Thanks to the incredible turn-out, “TreeTech 2019 – Growing avocados in a new era” was a fantastic success with over 80 growers from the avocado industry in attendance at the World Agroforestry Centre and more than 2600 minutes streamed live on Facebook. The event which focussed on the sustainable production of avocados brought together industry growers, leaders and thinkers to help shape meaningful discourse from boardrooms to orchards – inspiring a future of growing avocados which routinely deploys sustainability practices at every level.

Avocado growers are facing an exciting future with growing markets in the US, EU and China as the millennial consumer class matures. However, at the same time, the industry faces many challenges in the form of climate change, export regulations, pest control issues and public criticism of habitat loss and deforestation. By working closely with ICRAF, Goldsuite and Insect Science, we created a symposium programme around issues which avocado growers face on a daily basis. The course was made up of a series of lectures delivered by thought leaders in the topics of advanced nutrition, integrated crop and pest management and agroforestry.

The TreeTech concept was born out of the question of what IPM providers are doing to support the fast-growing avocado industry globally and closer to home in Kenya. We hoped this event would foster an extension of the technology enjoyed by veg and flowers to tree and fruit crops.

Dudutech Zimbabwe’s Phil Weller Selected for Nuffield Scholarship

Posted by

Phil Weller, Nuffield Scholar, in a field on his farm outside Harare, Zimbabwe.

Phil Weller, authorised Dudutech distributor for Zimbabwe, has been selected as a Nuffield International Farming Scholar for 2019. The prestigious global programme focuses on building personal capacity, propagating excellence in agriculture and driving thought leadership on local and international levels.

Since its establishment by Lord Nuffield in 1947, the scholarship has inducted 1,700 agriculturalists from around the world, and only 13 in 2019. The scholarship aims to develop leadership and expertise to keep the agriculture industry dynamic, competitive and at the service of society.

The programme is structured in three phases. The Contemporary Scholars Conference begins the journey in March, bringing together all 70 Nuffield Scholars from around the world for up to 10 days. Following that is the Global Focus Programme, in which the scholars will travel abroad to a country of interest for 7 weeks. According to Nuffield International, “scholars benefit from exposure to a broad range of agricultural systems, in very different political and social environments, whilst travelling in a close group of individuals of varying backgrounds during an intense programme.” The third and final part of the programme is the Individual Research Travels and Report, whereby the scholars travel to research their topic. Their 10,000-word report is then presented to a conference of peers, contributing to the global agricultural knowledge-base.

Nuffield International, the non-profit body which provides support and governance to the scholarship, has aligned with the UN Sustainable Development Goals, recognising the vital role agriculture plays in pursuing many of them. In doing so, Nuffield Scholars are brought to the front line to lead their industry towards a sustainable future all.

Dudutech is proud to be associated with Nuffield Scholar Phil Weller, who has decided to study “Integrated Pest Management (IPM) as the sustainable future for global agriculture,” which he affirmed in an interview. The research will focus on how IPM can make major global agricultural sectors more sustainable through the potential for the system to reduce industry reliance on chemical pesticides by increasing the use of biocontrols. Phil’s experience in the industry developed his view that “profit and sustainability go hand in hand and (IPM) is the key for the future.”

Weller said his IPM research aims to aid in addressing the global challenges of “residues on crops, resistance to chemicals and land pressure.” He said he hoped that “it will encourage farmers to look at agriculture in a more holistic manner with sustainability being the key.”

His personal ambition is to gain an up to date understanding of global trends in sustainable  agriculture, agricultural policies and to broaden his professional network. He went on to say that he hoped his research would help to give back to Zimbabwe in terms of bringing forward the latest IPM technology.

Weller’s earlier studies saw papers published on papaya fertiliser trials and avocados. As a grower of cut flowers for the export market, Phil developed a deep interest in Integrated Pest Management (IPM) to help combat pest and disease in a sustainable, environmentally friendly way. He credits using IPM on Tonsberg Farm, his own growing operation in Zimbabwe, as a key to accessing foreign markets, where the regulations are steadily becoming more restrictive against chemical controls.

To finance their studies abroad, Nuffield Scholars seek investment from key businesses in relevant fields. Beside Dudutech (Kenya), Phil Weller has received investment from Nufarm (Australia), Drip-Tech (Zimbabwe) and Nuffield International. The investors form a network to support and disseminate the research done through the scholarship. The Nuffield Scholarship aligns well with Dudutech’s own emphasis on furthering an understanding of global crop sciences through education and research.

As a Nuffield Scholar, the potential understanding gained from Phil Weller’s research journey while participating in the scholarship has far reaching effects on the future of sustainable agriculture and for Dudutech. Follow this story as it develops on our social media channels

Dudutech cutting edge pest controls now available in Tanzania

Posted by

Growers in Tanzania can now benefit from a range of Dudutech’s biological pest control products. The portfolio approved by Tanzanian authorities includes beneficial mites and fungi used to sustainably protect crops against Thrips, red spider mites and root knot nematodes. The products, traded as BEAUVITECH, MYTECH and PHYTOTECH, enable flower and vegetable growers to harness nature to protect their crops in a sustainable, environmentally intelligent way.

These solutions were specially designed and developed under a “by growers for growers” mantra to provide farmer-focussed alternative approach to crop protection. In the past, farmers relied heavily on chemical pest controls which are potentially harmful to the environment, people and long term economic viability of agribusinesses.

Thrips, red spider mites and nematodes can be difficult to effectively manage using chemicals alone. This is due to a confluence of problems compounding challenges such as resistance management, market restrictions, non-target effects and safety restrictions. When these issues arise, farmers suffer lower productivity, reduced plant quality and increased costs. Using biocontrols addresses each of these while protecting the long term future of growing and selling crops.

The Products

PHYTOTECH is one of Dudutech’s flagship biocontrol products, it deploys specially reared beneficial mites called Phytoseiulus persimilis, powerful natural predators which actively hunt and feed on red spider mites including their eggs, nymphs and adults. PHYTOTECH is safe to use and does not face natural resistance issues, unlike many routinely used chemical controls.

BEAUVITECH contains spores of a specially developed entomopathogenic (insect-killing) fungus called Beauveria bassiana which naturally targets Thrips in vegetables and flowers. When the spores come into contact with the target, they attach and penetrate the insect before feeding on internal tissue, killing the pest. Spores then emerge from the cadaver, ready to attack a new host. The formulation was designed to allow farmers to apply the product and safely interact with the crop immediately after spraying.

MYTECH contains formulated spores of Paecilomyces lilacinus, a nematophagous fungus which traps and digests root knot nematode adults, juveniles and eggs in the soil. MYTECH spores attach to a target nematode then form mycelia to trap it before invading and feeding on the host. The spores then emerge to continue the lifecycle on a fresh host. MYTECH is applied to the growing medium using drip irrigation or spray equipment to allow the fungal colonies to easily spread through the soil to infested regions in the crop. Chemical controls for root knot and other pest nematodes often harm beneficial non-target macro and micro organisms living in the soil around the crop roots. By using MYTECH growers can manage root knot nematodes without damaging the natural soil biome which crop plants rely on.

What this means for Tanzania

Livingstone Chepukel, Dudutech East Africa Sales Manager:
“Tanzania’s agriculture sector is large and growing but farmers face major challenges in sustainably protecting their crops against pests and diseases which ultimately impact on access to external markets and their bottom line. Dudutech’s entry into the market is an important step forward in securing the long term future of the agriculture industry in Tanzania.”

Flamingo commits $2.4million investment to Dudutech expansion

Posted by

Flamingo Horticulture Investments (FHI Ltd), a Sun Capital Europe portfolio organisation, announced that they will make a further investment of USD 2.4Million in subsidiary business Dudutech, Africa’s leading Biological Pesticide Manufacturer.

Dudutech a is high growth biotechnology business in operation since 2001 that plays a critical role in allowing their many international and Kenyan customers and the Flamingo Group to farm sustainably and adhere to farming and produce regulations across the globe.

To provide farmers with sustainable solutions, Dudutech’s team of over 250 technicians, masters and doctorate level scientists manufacture insect-killing fungi and beneficial predatory insects and mites, which are used as part of an Integrated Pest Management strategy, where farmers combine pesticides and traditional synthetic chemical pesticides to tackle agricultural pests and diseases.

Dudutech will direct the additional funding towards expansion of production facilities at the biofactory site in Naivasha, Kenya, including an additional 4ha of greenhouses and an insectary. The project is aimed at increasing production capabilities to provide additional beneficial predatory insects availability to meet growth in demand for biologicals and satisfy the needs of major growers in Africa, Europe and the Americas.

Thomas Mason, Managing Director Dudutech says:

We are incredibly excited to see Flamingo Horticulture Investments backing Dudutech. The new investment will be used to further expand the company’s manufacturing capacity. Alongside this investment Dudutech will be recruiting into its management team, broadening its product range and increasing the scope of its international operations.

This investment will allow us to grow our services to our customers in Africa, Europe and the Americas and ensure availability of our beneficial predatory insects, especially during peak seasons, where demand has outstripped supply in the past.

Martin Hudson, CEO Flamingo Horticulture Investments comments:

Under the stewardship of an outstanding management team, we believe that Dudutech has consistently demonstrated its ability to deliver on investment strategies, it now plays a critical role in the supply of insect killing fungi and beneficial predatory insects and mites for farmers globally.

A fascinating Cryptotech story

Posted by

One of Dudutech’s oldest clients, RedLands Roses, shared some very exciting news with us.

Our Technical Sales Operator, Hannah Kibiru, applied Dudutech’s product, Cryptotech, three times in a section of one of their greenhouses one month ago. Cryptotech (Cryptolaemus montrouzieri) is the most active Mealy Bug predator. Both the larval and adult stages of this predator attack all stages of mealy bugs.


Stefano Banella, IPM Manager at RedLands Roses, explains to us that two weeks ago he reported seeing one adult Chryptotech. Then last week he reported that they had noticed a number of larvae and adults feeding heavily in that section of the greenhouse. “I think it is quite exceptional” expresses Stefano to our Dudutech team.

Agrichemicals and ever more intensive farming will not feed the world

The latest frontier is Africa, where there is a new scramble to spread the agroindustrial model of farming. It may well be in Africa, however, that a different, more ecological vision of the food future emerges. I had a glimmer of it on a trip to a large-scale horticultural export company based on Kenya’s Lake Naivasha.

The company, Flamingo Homegrown, has abandoned its long and heavy use of chemical pesticides, partly in response to a campaign highlighting their effect on workers’ health, but partly too in recognition that they were on a losing treadmill of spraying and pest resistance.

They have reinvented their agriculture in a way that makes the science of agrochemical use look as primitive as a blunderbuss. Instead they employ groups of highly trained African scientists to study and reproduce in labs the fungi and microrrhizae in healthy soil that form intricate links with plant roots. Rather than waging chemical war on the land, they are working to harness its immensely complex ecosystems. They have built vast greenhouses dedicated to breeding and harvesting ladybirds to control pests biologically rather than chemically.

There is an another route to food security – and it is the polar opposite of three agrochemical giants bestriding the world.

A Dudutech Potato Story– Trichotech Drench

Posted by

Meet David, a loyal Dudutech supporter who enjoys helping his father with farming work in Zimbabwe. David and his father were offloading a shipment from farmer, Gareth Palmer, when they came across this 1.88kg potato! Gareth’s biggest potato weighed 2.08kgs!

Gareth has been using Dudutech’s #Trichotech product for his potato crop in conjunction with his other products. He has been using about 5-6 bottles of #Trichotech per hectare. He also had a #Whitefly problem and so used Dudutech’s #Lecatech to solve it. He used a double #Lecatech with a chemical to squash it and is now thinking of using Dudutech’s #Beauvitech to squash the potato #TuberMoth.

How nematodes ‘customise’ the crops they eat

Posted by

Invisible to the naked eye, nematodes that parasitize plants are a huge threat to agriculture, causing billions of dollars in crop losses every year.

New research shows that these tiny worms use a specialized hormone to help them feed from the plant—a finding that could one day lead to crop plants with enhanced resistance to these devastating agricultural pests.

“Cell cycle regulation is a key aspect of plant development and one of the first events altered during the formation of the feeding sites nematodes use to acquire nutrients from host plants,” says Melissa Goellner Mitchum, a researcher at the Bond Life Sciences Center and a plant sciences professor at the University of Missouri.

“These discoveries led scientists to suspect that cytokinin, a hormone that promotes cell division in plants, might play a key role in feeding site formation for nematode parasites.”

Doctoral student Carola De La Torre and postdoctoral fellow Demosthenis Chronis worked with Mitchum to determine if nematode infection alters the cytokinin signaling pathways plants use to regulate growth and development and how the process changes due to nematode infection.

“As part of our research, we examined the activation of different components of the cytokinin pathway in response to nematode infection,” De La Torre says. “Also, we evaluated numerous plants that lacked the presence of these components and found that most of these plants were less susceptible to nematode infection.

“These results suggested to us that these little worms are not only utilizing parts of a plant hormonal pathway that is important for plant growth and development, but they also are doing it in a way that allows them to cause disease.”

Mitchum’s team worked with Florian Grundler’s group at Rheinische Friedrich-Wilhelms-University of Bonn, Germany, who further analyzed the connection between cytokinin and nematodes. Using advanced genetic tools, they discovered that nematodes create their own form of plant cytokinin and that, by secreting the hormone into the plant, they actively control the cell cycle leading to the production of ideal feeding sites to support their development.

These findings show the ability of an animal to synthesize and secrete a functional plant hormone to establish long-term parasitism.

“Understanding how plant-parasitic nematodes modulate host plants to their own benefit is an essential first step in finding new technologies needed to develop crop plants with enhanced resistance to these devastating agricultural pests,” Mitchum says.

Advantages of using biopesticides compared to chemical pesticides

Posted by

Biopesticides, also known as biological controls or biocontrols, are organisms used to manage pests or diseases and are most notably used in agriculture. Biopesticides use natural food chains to manage pests and diseases by taking advantage of predator-prey or parasite-host relationships. With this method, growers can sustainably manage crop pests without harming non-target organisms, the environment or humans.

There are a few types of organisms which are typically used: natural predators, predatory mites, parasitoids, fungi and nematodes. The species chosen are isolated and thoroughly researched before only the best solutions make it to market.

Advantages of biopesticides (or biocontrols):

  1. Effect on non-target species

Biological control products typically target a narrow range of pests or diseases while non-target organisms, such as birds, bees, fish, humans and beneficial soil organisms, remain unaffected.

  1. Pollution

Since biological controls are naturally occurring organisms, at the end of their life they completely biodegrade and leave no harmful residues on the crop or in the environment. This feature helps promote the safety and well-being of people who work on farms and the environment.

  1. Cost

Biological control, as a part of IPM, works to achieve sustainable management of pests and diseases, keeping the pressure well below economically damaging levels. Pests and diseases do not develop resistance to biological controls. Since the rate of application will only change with pest or disease pressure, farmers can accurately predict input costs.

  1. Pest resistance

Records have shown that pests tend to become resistant to conventional pesticides thus proving that it is not a long-term solution, something that never happens with the use of organic pesticides.

  1. Market

As the ordinary consumer became aware of the dangers posed by synthetic chemicals, demand for farm products that have undergone organic treatments rose. This makes the use of these chemicals a potential risk as there’s a glaring possibility of incurring huge losses due to the consumer shunning your product.

Dudutech MD to Speak at the GFIA Summit 2016

Posted by

The GFIA Summit (Global Forum for Innovations in Agriculture), will be held in Abu Dhabi between the 16th – 17th of February, 2016. This is one of the most important global events in the agricultural industry’s calendar, where stakeholders meet to discuss and unveil the latest innovations in the industry.

What’s even more exciting is that, Dudutech’s Managing Director, Mr. Tom Mason will be a guest speaker at the conference. Drawing from the success of Dudutech, he will be speaking about innovations in agriculture.

As the leading biopesticide producer in Africa, Dudutech has overseen the research and development of innovative methods to combat pests and at the same time, reduce the effects of artificial pest control methods.

Built on the friendly slogan of ‘By growers for growers’, Dudutech’s approach to finding pest management solutions for farmers is unparalleled. This is because, while most of the newcomers in the industry push for company-profits-minded solutions, Dudutech develops its products with the farmer in mind. From the large scale rose flower producers, to the kitchen garden organic enthusiast who wants to lead a healthy life free from the disease causing residues of chemically treated products on the shelves. Both of these people, and the many in between, are considered during Dudutech’s production.

Dudutech goes further than developing products to providing a range of biological farming services. They are; certified trainings, scouting and monitoring, trials and laboratory services. These are essential for the implementation of a low residue, low socio-environmental footprint, fully holistic cost natural Integrated Crop Management Program.

In a recent interview by a leading national newspaper, Tom Mason summarises what Dudutech represents in a powerful statement, “It’s a holistic approach to farming where one utilises the full spectrum of environmentally safe farming products and technologies to their full potential.”

Agricultural policies in Africa could be harming the poorest

Posted by

Agricultural policies aimed at alleviating poverty in Africa could be making things worse, according to research by the University of East Anglia (UEA).

Published this month in the journal World Development, the study finds that so-called ‘green revolution’ policies in Rwanda – claimed by the government, international donors and organisations such as the International Monetary Fund to be successful for the economy and in alleviating poverty – may be having very negative impacts on the poorest.

One of the major strategies to reduce poverty in sub-Saharan Africa is through policies to increase and modernise agricultural production. Up to 90 per cent of people in some African countries are smallholder farmers reliant on agriculture, for whom agricultural innovation, such as using new seed varieties and cultivation techniques, holds potential benefit but also great risk.

In the 1960s and 70s policies supporting new seeds for marketable crops, sold at guaranteed prices, helped many farmers and transformed economies in Asian countries. These became known as “green revolutions”. The new wave of green revolution policies in sub-Saharan Africa is supported by multinational companies and western donors, and is impacting the lives of tens, even hundreds of millions of smallholder farmers, according to the study’s lead author Dr Neil Dawson.

The study reveals that only a relatively wealthy minority have been able to keep to enforced modernisation because the poorest farmers cannot afford the risk of taking out credit for the approved inputs, such as seeds and fertilizers. Their fears of harvesting nothing from new crops and the potential for the government to seize and reallocate their land means many choose to sell up instead.

The findings tie in with recent debates about strategies to feed the world in the face of growing populations, for example the influence of wealthy donors such as the Gates Foundation, initiative’s such as the New Alliance for Food Security and Nutrition in pushing agricultural modernisation in Africa. There have also been debates about small versus large farms being best to combat hunger in Africa, while struggles to maintain local control over land and food production, for example among the Oromo people in Ethiopia, have been highlighted.

Dr Dawson, a senior research associate in UEA’s School of International Development, said: “Similar results are emerging from other experiments in Africa. Agricultural development certainly has the potential to help these people, but instead these policies appear to be exacerbating landlessness and inequality for poorer rural inhabitants.

“Many of these policies have been hailed as transformative development successes, yet that success is often claimed on the basis of weak evidence through inadequate impact assessments. And conditions facing African countries today are very different from those past successes in Asia some 40 years ago.

“Such policies may increase aggregate production of exportable crops, yet for many of the poorest smallholders they strip them of their main productive resource, land. This study details how these imposed changes disrupt subsistence practices, exacerbate poverty, impair local systems of trade and knowledge, and threaten land ownership. It is startling that the impacts of policies with such far-reaching impacts for such poor people are, in general, so inadequately assessed.”

The research looked in-depth at Rwanda’s agricultural policies and the changes impacting the wellbeing of rural inhabitants in eight villages in the country’s mountainous west. Here chronic poverty is common and people depend on the food they are able to grow on their small plots.

Farmers traditionally cultivated up to 60 different types of crops, planting and harvesting in overlapping cycles to prevent shortages and hunger. However, due to high population density in Rwanda’s hills, agricultural policies have been imposed which force farmers to modernise with new seed varieties and chemical fertilisers, to specialise in single crops and part with “archaic” agricultural practices.

Dr Dawson and his UEA co-authors Dr Adrian Martin and Prof Thomas Sikor recommend that not only should green revolution policies be subject to much broader and more rigorous impact assessments, but that mitigation for poverty-exacerbating impacts should be specifically incorporated into such policies. In Rwanda, that means encouraging land access for the poorest and supporting traditional practices during a gradual and voluntary modernisation.

Organic Control of Aphids

Posted by

There’s a similarity that’s found in aphids, scale, mealybug and whiteflies. It is that they are are all sap-suckers. What’s more? They all release a sweet, sticky liquid that oozes from them as they suck juice from the plants. When this solution lands on the plant, sooty mould takes hold. This ashen-looking fungus does not infect plants, but it blocks the process of photosynthesis. This results in leaf drops and ugly sooty foliage on plant stems, leaves and fruits.

Although common in roses, aphids also attack vegetables such as beans, peas, melons, cucumbers and tomatoes, among others. In addition to sucking, they can also transmit other diseases from plant to plant. Their activities can result in curling and distortion in young foliage, yellowing of leaves and stunted growth in plants.

These soft-bodied insects are about 25mm long and usually wingless and pear-shaped. Depending on the climatic zone, host or species, they can be black, green, grey or milky-cream. They have mouths designed to suck juices from plants.

Aphids’ life cycle is a little different as females give birth to young live and can do so without mating. This they do at a very high rate.

Organic Control

Moist cloth

If you are handling a small area, you can simply use a moist cloth to wipe aphids from plants. This can be time consuming but the results are instant. Do this for two or three days while monitoring the results.

Hose spray

Spray affected plants with a strong jet of water from a hose. Return after a couple of days and see if aphids have left your plants alone. You can then wipe away the soaked aphids or prune the plants.

Attract beneficial insects

This can be done by planting companion plants that attract predators such as ladybirds that can wipe out aphids. Or, easily get organic bio-controls and reduce the time and resources required to attract them to your plants.

Leave ants alone

There is a misconception among many farmers that ants bring aphids to plants. This is not true. In fact, aphids land there first then ants get attracted by the honeydew. That being said, ants are important predators and decomposers in the farm and often drag aphids away.

Do not over-fertilise

Feeding aphid-infested nitrogen-rich fertilisers only increases the aphids’ feed and result in them multiplying.


Weed out your ornamental garden or patch frequently to keep aphids away


Prune shoots that have been infested by aphids and throw them away.

The Case for Change

There are, essentially, two truths today about African agriculture: significant progress has been made, and there is potential for much more. Several figures point out the progress. Agricultural production has increased 160 percent over the past 30 years, far above the global average of 100 percent, although lagging South America (174 percent) and Asia (212 percent). Eighteen Sub-Saharan African countries have reached the Millennium Development Goal’s first target of halving the proportion of people who live in poverty. Country-level programs (the Ethiopian Agricultural Transformation Agency is one example), cross-border initiatives (such as the Comprehensive Africa Agriculture Development Programme), and pan-African groups (such as the African Development Bank, the African Union, and the New Partnership for Africa’s Development) have all played important roles in these advances. Africa’s room for more growth remains vast, however. The continent remains a net importer of food, even though it has 60 percent of the world’s uncultivated arable land, and production has struggled to keep pace with a fast-growing population. To meet the needs of the 2 billion population expected in Africa in 2050, agriculture is the key. Agricultural transformation will build social cohesion, drive beneficial continental trade, provide a platform for sustainable exports to the rest of the world, and, most importantly, help create millions of jobs while pulling subsistence farmers out of poverty

What Has Hampered Africa’s Development?

Many factors have hampered Africa from reaching its full potential. As its population has doubled overall and tripled in urban areas in the past 30 years, agricultural production and food security have had to keep pace. Africa is the only continent where the absolute number of undernourished people has increased over the past 30 years. There are many reasons for the challenges, but three in particular stand out.

A multitude of (somewhat uncoordinated) initiatives. There are many great initiatives, with local and foreign funding, that aim to enhance the state of agriculture in Africa. However in many cases these programs are fairly uncoordinated, often have overlapping mandates, and, to a certain extent, compete against one another for funding and private investments. Pan-African coordination and focus is critical to the future.

Good ideas but not enough implementation. Forests have been harvested to produce the paper to document all of the strategies that have been developed. Through the years, countless commitments have been made and plans have been developed. Although progress has been made, now is the time for this to be all translated into concerted action.

Insufficiently developed ecosystems. The ecosystems required to develop a solid agricultural market in Africa are often underdeveloped in terms of political commitment, the quality of government, infrastructure availability, and regulatory frameworks, among other factors. There is a need for a true commitment among governments and stakeholders to put the basics in place to make these ecosystems happen.

Africa’s Agricultural Transformation at Three Levels

The value chain from farmer to market is central to any potential transformation of Africa’s agriculture. Transformation at three levels can bring broad benefits to this farmer-to-market value chain: Farmers. Smallholders contribute up to 80 percent of Sub-Saharan Africa’s food supply, according to the UN’s Food and Agriculture Organization, and Africa has an estimated 33 million smallholder farms, according to the International Finance Corporation. Increasing farmer capabilities would increase Africa’s output and, as a consequence, help solve Africa’s poverty and malnutrition crisis. Farmer-level transformation should seek to increase yields, reduce post-harvest losses, improve market access, and increase product margins. Transformation requires granular-level interventions that form the basis for sustained economic and societal success. Enablement in areas such as education, infrastructure, water management, and regulations is crucial as well. Public-private initiatives can ensure capability-building support and the development of structures in areas like financing. These initiatives are, by nature, very local. However, they can be facilitated from a pan-African perspective in three ways:

-Best practice sharing. Providing a best-practice clearinghouse for farmer associations and governments.
-Support of governments. Aiding governments in skills development and coordinating cross-country initiatives.
-Public-private partnership initiatives. Creating a first “port of call” for large corporate and institutional investors to ensure investments’ effectiveness and coordination.
Markets. Farmers need access to markets to earn their fair share of the profits. Good markets, in turn, provide food security for the population and facilitate Africa’s agricultural self-sufficiency. They are at the center of an agricultural ecosystem that forms the basis of sector development.Making markets work is a supply chain infrastructure and information issue. Governments and private investors need to ensure that sufficient roads, warehouses, processing facilities, and other infrastructure are in place to get products to increasingly urbanizing markets. Farmers need access to information to deliver products to the markets that offer the best price advantages. At the regional and country levels, government and market actors need to create the markets that allow the trade of homegrown products. These initiatives in general cut across the wide spectrum of crops and products produced. Markets are often developed at country level, but a pan-African strategy would include the best practice sharing and public-private partnership support we highlighted for the farmer level. Additionally for markets, enhancing inter-African cross-border trade would help facilitate the enablers that remove trade barriers and inefficiencies between countries and free up the traffic of agricultural produce across Africa

Clusters (macro). With agricultural ecosystems in place in this final, macro level of transformation, Africa can become a major agricultural player globally, facilitating the export of its products outside of Africa. Cluster-specific initiatives are typically based on product availability and production competence. Better supply, from farmers who have learned about and invested in improving their yields and product quality, helps build a stronger market. Dairy exports from New Zealand are one successful example of the development of a world-class ecosystem. Years ago, the New Zealand Dairy Board created a platform for best-practice sharing among its members to improve productivity and product quality and actively created export markets for excess products. Some of the Dairy Board’s activities became part of a new cooperative called Fonterra—now one of the leading global milk processors and dairy exporters, with roughly 22 billion liters of milk produced annually. Fonterra also produces more than 2 million tons of dairy ingredients, specialty ingredients, and consumer products annually—95 percent of which are exported. This allows New Zealand to punch above its weight in the global dairy market. Cluster-specific export initiatives like Fonterra should be a government goal in Africa. From a pan-African perspective, identifying sectors and coordinating initiatives across countries are essential steps to a transformation strategy.

Building Pan-African Ecosystems: Financing, Sustainability, and Government Enablement

African smallholders do not yet benefit from best-in-class global farming practices. They are often trapped in a vicious cycle that prevents them from improving their productivity and income. These farmers are, however, the fabric of African rural societies. Their future success is crucial as Africa’s population grows and urbanizes. Strategies are only as effective as the change they bring about. Truly transforming African agriculture at the farmer, market, and cluster levels depends on three key levers: financing, government enablement, and sustainability (see figure 1). FG-Africas-Agricultural-Transformation-Opportunity_01

Financing will fund the improvements in the value chain on both the micro (farmer) and macro (export) levels. Government enablement means putting in place the regulations and structures that foster a strong business environment—for example, giving farmers title to the land they use, enabling them to use that land as collateral for loans for investments that can build. The development will become sustainably effective through the close interaction of public and private enterprises. Good governance is a prerequisite to ensure funds are applied in an effective and efficient manner. Farmer development leads to getting better products to the market. If markets are developed and allow for transparent pricing, the farmer gets a fair price and can become self-sufficient. As more farmers gain access to markets, it creates an ecosystem with enough resources to invest back into improved agricultural processes, which in turn improves yields and lowers losses. This will then facilitate clusters of best-in-class agricultural practices by crop and region that can succeed in the export market. All in all, it’s a self-propelling cycle that leads to advances and supports development of aggregation constructs (such as cooperatives), which help farmers jointly invest in productivity improvements and facilitate access to market (see figure 2). FG2-Africas-Agricultural-Transformation-Opportunity_02Eight specific actions will optimize and grow the entire value chain. These are: Bring innovation to existing farm dynamics Improve access to markets Apply technology to increase market transparency Enhance farmer financing models Use targeted government enablement

Encourage sustainable agriculture practices Empower women Empower youth The following sections provide a brief overview of how Africa can move forward with these eight actions.Bring innovation to existing farm dynamics Smallholders have to understand a complex set of capabilities to bring the highest returns. These include mechanization (equipment for soil preparation, planting, cultivating, harvesting, and processing), irrigation, inputs (seeds, fertilizer, and the like), crop protection, product quality management, post-harvest protection (early processing, storage facilities, siloes, and warehouses), transportation, and direct access to market. The Gap Analysis Tool for Agriculture (GATA), developed jointly by Grow Africa and A.T. Kearney, provides farmer associations with a best-practice framework for smallholders, allowing for country- and crop-specific assessments of how they can improve productivity. The underlying objective of the GATA is to identify opportunities to increase farmer profitability and productivity by:

  • Conducting a detailed analysis of value chains by region or country and by crop
  • Enabling farmers, farmer groups, agricultural departments, and agencies to compare their practices against global and regional benchmarks
  • Identifying agricultural value chain gaps and the investments required to close gaps
  • Calculating the viability of smallholders closing these gaps
  • Determining and providing visibility to decision makers and investors on which strategic interventions assure the highest benefits

Improve access to marketsOne often-overlooked success factor is the structure of market incentives across the value chain from production to market (see figure 3). Unequal distribution of market power and insufficient access to the profit pool at various stages can have huge implications for farmers in low-income countries. Improving market access and transparency can balance market power, especially for smallholders. FG3-Africas-Agricultural-Transformation-Opportunity_03

Modern agricultural value chains have stringent requirements regarding volume, quality, and timely delivery. Combined with a lack of information on prices and selling opportunities and an abundance of “roadside traders” seeking high margins for low value added, smallholders generally find themselves with limited negotiating power and little incentive to grow beyond their current circumstances and to obtain their fair share of the profit in the value chain. Improving farmers’ information bases and introducing value-added market intermediaries are a prerequisite for farmer success. Many smallholders also lack physical and economic access to lucrative markets for their crops because they are physically isolated by distance, poor roads, and lack of access to adequate transport, and constrained by small crop quantities available for sale, inconsistent levels of quality, a need for immediate payment, and limited storage capacity. This highlights the need for public-private initiatives to build a physical supply chain (with storage, processing, and transport capabilities) that allows for quality products to be supplied to the markets in use. With unreliable information on production trends and prices and a lacking infrastructure, few smallholders engage in demand-driven or market-informed production, leading to inadequate production planning and cycles of production surpluses and deficits, which in turn lead to fuel price volatility. One solution to these problems comes from targeted government enablement, which gives smallholders greater market access and information

Apply technology to increase market transparency Ironically Africa has all the opportunity to jump the development curve and become a leader in applying technology to smallholder farming. The continent has high cell phone penetration and even in rural areas connectivity is good. Advanced cell phone applications (like banking, weather information, and market data) can help smallholders tremendously in their decision making and in improving their productivity. There are many examples of innovative uses of state-of-the-art technology that needs to be scaled across Africa (for example, small soil-testing devices that send data to a lab in Europe, which in turn provides soil-specific fertilizer advice by text message to the farmer). The interests for non-traditional private investors and African smallholder farmers go hand-in-hand. Africa provides a massive opportunity to test and commercialize data technology innovations and farmers are longing for the data that provides them with productivity and market opportunities. In specific, non-traditional agricultural sector players such as banks and telcos could step into this field and open new markets for themselves.

Enhance farmer financing models Affordable access to financing remains one of the most significant barriers to investment in agriculture. Access to financial services is critical for smallholders to invest in productivity, improve post-harvest practices, smooth household cash flow, enable better access to markets, and promote better risk management. In addition to formal financial institutions, input suppliers and product buyers often act as alternative financing channels for commercial and semi-commercial smallholders and cooperatives. Formal financing institutions are often hesitant to lend to commercial smallholders for a variety of reasons, primarily related to the scale of risks they face, including the heterogeneous nature of smallholder farmers, irregular cash flows caused by seasonality risks, systemic risk of flood, drought, and plant disease, and the lack of viable risk mitigation tools such as guarantees, asset collateral, and insurance. Financing institutions also struggle with loan processing and disbursement, customizing products for individual circumstances, and providing non-financial services, such as financial education, that will improve farmer success rates but are not core to the business. Farmers’ risks can vary widely. They are generally lower when farmers have stronger relationships with buyers, as this can bring techniques such as shared credit screening, monitoring, and collection, and the use of alternative collateral (such as sales contracts). When farmer-buyer relationships are weak, predatory lending becomes a bigger risk, and smallholders tend to be more focused on subsistence farming. Expanding lending to smallholders depends on several factors

Gaining detailed client knowledge at the smallholder level

Offering flexible loan terms that are adaptable to the diverse profiles of smallholders

Employing diversified risk management tactics, such as cooperatives and asset pooling

Training risk officers to better identify and manage smallholders’ risks

Re-engineering and adapting processes to ease applications and improve disbursement speed

Use targeted government enablement In addition to addressing smallholder needs directly, government can take steps to maximize returns on investment by creating an enabling environment for farmers in the following areas: land access, availability, and security; infrastructure; water management; education; labor; health and housing; security; investor environment; market structure; and public-private partnerships

The right enablers can have an outsized impact on agricultural outputs. This is exemplified by sustainable and equitable access to water.

Promoting techniques such as on-farm water management, rainwater harvesting, and conservation can potentially triple crop yields.

Improving rural water infrastructure can improve productivity, especially for women who spend hours a week collecting water for domestic and agricultural use.

Water capture and storage solutions can mitigate the impact of rainfall uncertainty.

Well-negotiated and managed private-sector presence in commercial agriculture can ensure fair access to water for smallholders.

Empower women Many studies suggest that female empowerment can speed up development, as women reinvest their incomes in their families. For example, in Brazil, when income is a mother’s responsibility, a child’s survival probability increases by 20 percent; when the same happens in Kenya, a child is about 17 percent taller. If women worldwide had the same access as men to productive resources, yields could increase by 20 to 30 percent. The FAO estimates that gains in agricultural production alone could lift as many as 150 million people out of hunger. Most people today recognize the opportunity to close the gender equality gap; however, words of support only go so far. Recent work by the World Bank and the ONE campaign point to several barriers that women currently face in agriculture, including struggles finding adequate labor on their farms, unequal access to inputs, fair access to quality farmland, access to knowledge and training in farming methods, and a long-standing gender gap in education. Empower youth Sub-Saharan Africa’s population dynamics offer a unique opportunity, if managed well. Half of the population is younger than 25; every year between 2015 and 2035 there will be a half-million more 15-year-olds than the year before (see figure 4). This demographic dividend could radically accelerate Africa’s transformation if properly harnessed.


Over the next decade, however, as few as one in four Sub-Saharan African youth will find a wage job, and only a fraction of those jobs will be “formal” jobs in modern enterprises. Thus, agriculture will be central to providing meaningful and rewarding work. More than two-thirds of the young people who work in rural areas already work in agriculture, and most will remain there, even if the non-farm sector develops rapidly. As such, it will be important to help youth see farming not as an occupation of last resort, but rather one of opportunity and skill. Broadly speaking, agriculture offers three potential pathways for rural youth: full-time work on family farms; part-time farm work, combined with running a household enterprise (which can include the sale of farm services or inputs); and wage work. Several common constraints affect youth in agriculture: credit and financial services, land policies, infrastructure, and skills. Of these, only skills needs to specifically address youth at this point, as the others affect the wide pool of smallholders, regardless of age. In some countries, agricultural vocational institutes have traditionally provided these skills, but these institutes have mixed records of accomplishment; there is often a disconnect between academic teaching methods and the need for on-the-ground practical training. Well-thought-out extension programs and farmer-field schools have a bigger impact, especially if these are combined with support programs to entice youth to seek a living in farming

Encourage sustainable agriculture practices There are two simultaneous objectives here: improving the lives of Africans while minimizing environmental impact and ensuring that natural capital is not depleted. These objectives can be at odds with one another—in truth, agriculture is both a contributor to and victim of climate change—yet they can also be complementary. Sustainable farming, when done well, adds immediate value to the farmers as it increases the longevity of their operations and increases the value of their product

Cluster Development: Ensuring Viable Exports

With ecosystems in place, agriculture and agribusiness are huge economic opportunities for Africa, particularly if they can become revenue generators through an export model and enhance the continent’s balance of trade through value-adding operations. According to the World Bank, agriculture and agri-business will by 2030 be a $1 trillion industry in Sub-Saharan Africa, up from $313 billion in 2010. Agribusiness can help jump-start economic transformation through the development of agro-based industries that bring much-needed jobs and incomes. Successful agribusiness investments in turn stimulate agricultural growth through new export markets. These markets play either at the high-volume, low-value end of the market, or, ideally, they retain most of the value in Africa by incorporating value-added steps and local beneficiation in the value chain

Conducting a cluster review can help countries identify more value-retention opportunities. The challenge is identifying what crop types will be suited to export, where those crops are currently cultivated, and the current stage of excellence by crop (see figure 5).
Africa has traditionally struggled to compete as an agricultural exporter, starting with the challenges we outlined earlier in this paper. Erratic legislation impacting levies on seeds, fertilizers, and agriculture processing equipment, and duties on exporting agricultural output, can hamper exports. These key constraints vary by country and value chain. As such, it is instructive to look at select African countries and how their export value chains differ, and how the right solution can bring export success to Africa.
Rice in Senegal.
Rice has in recent years become Africa’s largest and fastest-growing import, valued at $3.5 billion, or nearly half of total consumption, in 2009. Urban consumers are seeking more storable and easily prepared foods, and higher-income consumers are showing a distinct preference for higher-priced imported rice with aromatic qualities. Given the size of domestic markets and good rice-growing conditions in Western Africa, several governments have begun raising import duties on rice to boost local agriculture and production. The improved policy incentives, coupled with higher world prices, have brought sharply higher local production in some countries, with private partnerships taking control of elements in the value chain. To determine global competitiveness, Senegal benchmarked value chain costs against the world’s leading rice exporter, Thailand, for both white rice and aromatic rice. In Senegal, rice from the Senegal River Valley is produced under irrigation and partial mechanization delivers the crops at costs only slightly above those in Thailand. With relatively efficient milling and transportation, local rice can be quite competitive, even more so if aromatic rice varieties can be produced commercially at the correct scale and quality. Senegal has made major progress increasing yields to 3.6 tons per hectare nationally (and more in irrigated areas). Competitiveness has been held back, however, by the difficulty of accessing secured, tradable land rights. This discourages significant private investments in irrigation systems, which is key to increasing production to boost exports. Nigeria is following a similar path in limiting rice imports, developing policies to incentivize local cultivation and allowing for exports to neighboring regions. It is clear that the potential and willpower are there in West Africa for a more effective rice value chain that ultimately can be a solid base of exports.
Maize in Zambia.
Maize is a crucial food staple in Eastern and Central Africa, with per capita consumption in some countries exceeding 100 kilograms, and feed consumption growing 6 percent annually. Most years, Zambia (133 kilograms per capita consumption) is self-sufficient, but there is substantial room for growth. With more than five million hectares of uncultivated land suited to maize production (nearly 10 times the current area), Zambia could become a breadbasket for its region. High yield and price risks and a lack of suitable financing and agri-insurance options have constrained further expansion thus far. For now, a handful of large- and medium-sized farms produces more than half of the country’s maize; at the other extreme is a huge pool of poor smallholders who do not produce maize at all and struggle to meet their daily needs. Helping these farmers meet their potential is key to bringing Zambia to its full potential. There are a few key steps to make this happen. Transport costs are high, so affordable access to a well-run port is vital for trading any surplus maize. Higher fertilizer costs and limited mechanization result in higher labor costs, so improving mechanical harvesting will have an exponential effect on efficiency.
Identifying more clusters in Africa
Those examples highlight the varied opportunities for Africa to becoming an agriculture-trading powerhouse. The challenge lies in how to increase the portfolio of crops that can be exported at world-class productivity levels. At first, the focus should be on clusters with established comparative advantages and strong market prospects. With resources few and challenges large at first, a strong focus on a few strong locations or value chains offers the opportunity to pilot cross-country collaboration and difficult reforms, demonstrate success, and learn from scaling efforts. It also channels scarce resources most effectively to tackle a critical mass of issues, whereas scattered reforms and public investments may find little success, given the long list of constraints affecting agribusiness. A tight focus on a particular area or value chain may also increase the chances of achieving sensitive and complicated cross-cutting reforms (such as piloting fertilizer and land reforms) and dealing with vested interests between governments and private institutions or investors. Figure 6 offers an overview of some of Africa’s cluster opportunities. FG6-Africas-Agricultural-Transformation-Opportunity_06

The right clusters are driven by interactive, iterative, evidence-based analysis in which the main opportunities and constraints are identified through a combination of desk research, expert interviews, and workshops. In general, clusters with competitive advantage and already-proven investor demand are preferable over attempts to initiate new industries in new areas. Key policy reforms need to come before committing to large public investments. Priorities and action plans will need to be flexible enough to meet unanticipated cluster opportunities, yet also allow for constraints that will inevitably emerge. Finally, and crucially, strong governance and monitoring systems should be put in place to correct or terminate failures but most importantly replicate and scale up successes. It is time for Africa to grow!

Let’s Get Going

A few key numbers highlight the opportunity—and the challenge. To meet growing global food demand, production must increase by an estimated 50 percent by 2030. Sub-Saharan Africa’s 33 million smallholder farms—a number that will increase rapidly as the population continues to increase—contribute up to 80 percent of the region’s food supply. Improving the odds of prosperity for these farmers lies at the heart of prosperity for African agriculture. Success at the farmer, market, and cluster levels requires assistance from many sources.

Governmentsneed to focus on significantly improving the enabling environment for local agriculture, particularly as it comes to land rights, infrastructure, market access, and elevating women’s roles in society.

Pan-African institutions such as the African Union can help develop cluster opportunities across the continent and promote intra-Africa trade and best practice sharing.

The private sector can help invest with funds and knowhow, understanding that Africa’s potential for growth and its untapped arable land offer huge opportunities in spite of the risks. Public-private partnerships can unlock value, as long as both sides share the onus of success. No longer must Africa go hat-in-hand to feed its vibrant and resourceful population. It can help its own people feed themselves, their villages, towns, and countries. As scale and quality develop, export markets from the continent can flourish, leading increasingly to not just poverty alleviation but wealth creation. As more inhabitants see the promise of a better future in agriculture, many more clusters will be developed, truly making Africa the breadbasket that the world so desperately hungers for. It can be done. Now is the time to put our shoulders to the wheel.

Research: Weed blasting offers new control method for organic farmers

Posted by

Weeds are a major scourge for organic growers, who often must invest in multiple control methods to protect crop yields. A relatively new weed control method known as abrasive weeding, or “weed blasting,” could give organic growers another tool. The method, recently field-tested at the University of Illinois, is surprisingly effective.

In conjunction with plastic mulch, abrasive weeding reduced final weed biomass by 69 to 97 percent compared to non-weeded control plots, said U of I agroecologist Samuel Wortman.

Abrasive weeding involves blasting weed seedlings with tiny fragments of organic grit, using an air compressor. For the current study, grit was applied through a hand-held siphon-fed sand-blasting unit connected to a gas-powered air compressor, which was hauled down crop rows with a walk-behind tractor. The study looked at a number of grit sources: walnut shells, granulated maize cob, greensand, and soybean meal. If applied at the right plant growth stage, the force of the abrasive grit severely damages stems and leaves of weed seedlings.

Wortman found no significant differences between the grit types in terms of efficacy. “When it leaves the nozzle, it’s at least Mach 1 [767 mph],” Wortman noted. “The stuff comes out so fast, it doesn’t really matter what the shape of the particle is.” Because ricocheting particles can pose a risk to the applicator, Wortman advises using protective eyewear.

Blasted grit does not discriminate between weed and crop seedlings, which makes it important to use this method in transplanted crops that are substantially larger than weed seedlings at the time of grit application. Although some visible damage occurred on stems and leaves of both tomato and pepper crops, the damage did not affect marketable fruit yield. Studies are ongoing to determine whether abrasions on crop tissues could result in increased susceptibility to disease, but early results show little effect.

Importantly, plots with plastic mulch and one or more blasting treatment achieved the same fruit yields seen in hand-weeded plots, and 33 to 44 percent greater yields than in non-weeded control plots.

An additional benefit of weed blasting is the potential for growers to use organic fertilizers, such as soybean meal, as blasting material. “We expect that abrasive weeding could contribute between 35 and 105 kg nitrogen per hectare [31 – 94 lbs per acre] to soil fertility.” The idea that a grower could both fertilize and kill weeds in a single pass is appealing, but it is still unknown whether the fertilizer would be available for plant uptake within critical windows.

According to Wortman’s research, weed blasting does affect some weeds more than others. Essentially, the smaller the seedling, the better. Also, seedlings whose growing points are aboveground (annual broadleaf species) are more susceptible to blasting than seedlings whose growing tips are located belowground (grasses and broadleaf perennials). Finally, Wortman noted that the presence of plastic mulch seemed to factor strongly into the equation. Weed blasting alone “is not a silver bullet, but it is an improvement,” he said.

The method is now being tested in different horticultural crops, including broccoli and kale, with and without additional weed control methods. Early results suggest that the presence of polyethylene mulch or biodegradable plastic mulch strongly enhances the success of weed blasting, as compared with straw mulch and bare soil. Wortman and his collaborators have also developed a mechanized grit applicator, which they are currently testing.

How to find a market for your farm products

Posted by

You have spent a whole season tending to your crops, all the while dreaming of how much you will earn when your produce reaches the market. Along the way you even found them healthy enough and #instaworthy. Now they are ready for harvesting but, to where? All of a sudden the fantasy evaporates and in sinks reality: You don’t know where to sell them! How will you get that money?
Here are a few places to get you started;

Do your homework

Before setting off on your journey to farming success, do some research. Find a niche and determine if there is demand for your intended crop. The lack of a product in the market could be due to arrange of reasons. From the lack of demand to the cost of production being higher than the potential returns.

Consider organisations
Instead of selling to individuals or small markets, consider applying for tenders in institutions and the government. Start with inquiring about in those found around your local area.

Exporting need not necessarily mean out of the country. You can sell to another town or city. When doing this, remember to include the transportation costs in your calculations. If you can afford your own transport, this can lower the cost significantly.

Establish a new market
Sometimes all you need to do is take the leap of faith and establish your own market. Remember to base it on your research though as some factors e.g religious practices and local customs might be the reason a certain product is not available in a certain area.

Local market
You can also start small. Find a stall at your local market and start building a loyal customer base. Depending on your skills, this can turn out to be a huge opportunity as you expand.

Closer look reveals nematode nervous systems differ

Posted by

Nematodes, an abundant group of roundworms that exist in nearly every habitat, have long been used as model organisms for studying the function of neurons – the basic unit of animal nervous systems. For years, it was assumed that neuron anatomy was remarkably similar across this large and diverse group. A recent study by University of Illinois researchers turns that assumption on its head.

“It was a comparative study looking at all of these different species of nematodes, including some parasites, and seeing that there are some substantial differences in the number of neurons in the ventral cord,” says U of I nematologist Nathan Schroeder.

According to Schroeder, discovering this degree of variation across the group suggests that neuron number and anatomy may have changed numerous times during nematode evolution. This is significant because the evolution of nervous systems is notoriously difficult to study in complex higher animals. Being able to study the relatively simple nervous system in nematodes can shed light on some basic research questions in nervous system evolution.

“This group of animals has the simplicity that makes it easy to work with in the lab, but there are these differences across species. So, we can target that and figure out how nervous systems are evolving.”

On a more practical level, the results of this study may lead to development of new nematicides – pesticides that target plant-parasitic nematodes.

“We know from some of the old nematicides that the nervous system is a very effective target. Unfortunately, some of those nematicides were very broad spectrum and would target anything with a nervous system, including us,” Schroeder noted.

The study showed that soybean cyst nematodes, a major crop pest in Illinois, may have unique neurons that could be targeted by new nematicides to avoid harming beneficial soil organisms. More research will be required to determine whether such a product could be developed, but the study indicates that the potential may exist.

The authors are now focusing their attention on soybean cyst nematodes to identify unique neurons and to learn more about how those neurons affect the movement of the microscopic roundworms in the soil and in soybean plants.

Aphids balance their diets by rebuilding plant amino acids

Posted by

Aphids suck up an almost endless supply of sugary sap from their plant hosts. They can survive on this junk food diet because bacterial partners help them convert the handful of amino acids in the sap into other, essential amino acids–not by recycling them, but by breaking them down and rebuilding from scratch, a new study finds.

Scientists have long assumed that aphids either use these amino acids directly or convert their carbon skeletons into other amino acids, which they use to make proteins. But by following the fate of carbon and nitrogen atoms ingested by the aphids, BTI scientists Georg Jander and Meena Haribal found that amino acid synthesis takes a very indirect route. Their findings appear in the Journal of Experimental Biology.

“We were surprised,” said Haribal, a research associate. “We didn’t know that they would deplete everything and make it from scratch.”

Plant sap is such a limited food source for the aphid because it predominantly contains four amino acids–glutamine, glutamate, asparagine and aspartate–which serve as the primary nitrogen source for the aphid. Plant roots synthesize these amino acids to transport nitrogen compounds, which they take up from soil.

To keep from starving, aphids have evolved a symbiotic relationship with a bacterium called Buchnera aphidicola, which helps to provide essential amino acids. Buchnera is an endosymbiont that can no longer survive independently outside of the aphid.

Earlier studies of the aphid genome suggest that the insect uses the carbon backbone of the plant amino acids to build the rest of the amino acids that they need. Scientists have also used amino acids labeled with radioactive carbon and nitrogen atoms to see where these amino acids end up, but these experiments were not precise enough to show how individual carbon and nitrogen atoms move through the insect’s metabolism.

Haribal fed pea aphids (Acyrthosiphon pisum) a diet of sugar sap and amino acids containing heavier isotopes of carbon or nitrogen–rare atoms that have extra neutrons in their nuclei and thus higher mass–that can be detected using a mass spectrometer. She supplied the insects with the liquid by sandwiching it in between two layers of Parafilm, which the aphids accessed by poking their needle-like stylets through the film.

Once the aphids had incorporated the isotope-labeled amino acids into their bodies, their structures were broken up and analyzed with a GC-MS, which separates out the individual pieces and allowed Haribal to figure out where the heavy carbon and nitrogen atoms ended up.

Jander and Haribal saw that the amino acids inside the aphid’s cells were a mixture of heavy and light atoms, indicating that the plant amino acids had been completely dismantled and remade. Even aspartic acid, which the researchers supplied in bulk to the aphids, was broken down and reconstructed.

“Because they have an unbalanced diet, whatever amino acids they get, they just break it down and resynthesize,” said Haribal. She suspects that this strategy is a result of their limited diet, coupled with the fact that levels of amino acids can vary greatly within plants, depending on the available nitrogen sources. Breaking down all amino acids into their components to make essential amino acids and other molecules, such as DNA, likely evolved as the most efficient process.

Haribal is interested in exploring this phenomenon in other species. Many animals subsist on unbalanced diets but have gut microbes or symbionts that break down their diet and provide more nutrition. For instance, similar to aphids, cows can survive on a diet with an imbalanced amino acid content because their rumen bacteria contribute to the supply of these essential nutrients.

“Lots of insects feed on only one thing, so they have to have some way of getting a balanced diet,” said Haribal. “They have to get all the essential amino acids from somewhere.”

Role of IPM in reduction of pesticide residues in export beans

Posted by

French bean (Phaseolus vulgaris L.) is the most important horticultural crop in Kenya and accounts for over 60% of all exported vegetables. The main share of production is the small scale farmers who contribute more than 80% of production, and rely mainly on pesticides for pest management. French beans production involves high use of pesticides withm Many farmers reportedly applying up to 11 sprays per season, resulting in residue problems. This is partly fuelled by consumers in the developed countries, who form the bulk of the market for the French bean crop from developing countries, demanding for French beans with specific attributes such as size and spotlessness. This therefore, encourages farmers to rely increasingly on the use of pesticides to control pests. But the acceptable tolerance for pesticides residue in French beans is a major concern to the consumers. Among measures put in place in the importing countries are standards that require food products to meet prescribed maximum residue levels (MRLs) and another to reduce exposure of farm workers and other non-target fauna and flora. Emphasis is placed on consumer safety by use of approved less toxic pesticides and strict observance of the pre-harvest intervals which prescribes the latest date for pesticides use for ensuring safe residue levels.

In Kenya, there is growing evidence to show that alternative approaches and products are effective at managing pests without the side-effects associated with reliance on pesticides. Many farmers are successfully implementing Integrated Pest Management (IPM) on many different types of crops.

Dudutech has experience and proven track record in developing alternates to pesticides and in training and information on Good Agri-Practices (GAP) aimed at of giving farmers the skills, knowledge and confidence to make ecologically, socially and economically sound decisions on crop health. The alternatives such as traps, pheromones, and biocontrol products that play a role in IPM strategies are widely available. There is a wide range of Biological Control products (BCPs), that Dudutech is currently licensed to manufacture and distribute. The main products for French beans-IPM solutions are (Lecatech® (Lecanicilium lecani) for the control of whiteflies, thrips and aphids; Beauvitech® (Beauveria bassiana) for the control of thrips and whiteflies; Mytech® (Paecilomyces lilacanus) for the control of plant parasitic nematodes; Nematech H® (Heterorhabditis bacteriophora) for the control of cutworms, caterpillars and leafminer and Trichotech® (Trichoderma spp.) for the control of Fusarium, Pythium, Sclerotinia and Rhizoctonia).

What the industry desperately needs is an integrated approach to pest management. We need products which will replace pesticides. This ensures French beans do not exceed set MRLs. This approach has been adopted mainly by large scale producers who constitute over 20% of French beans production, while increasing farm income. Declaring IPM as the crop protection approach of choice is the way to go.

Biological pesticides are key to improving sustainability

Finlays Horticulture, a supplier to M&S, are moving away from using synthetic pesticides, in response to increasing concerns over the effect they are having on the environment. With insects becoming more resistant to synthetic pesticides as well as the unknown effects that they may be having on farm workers and consumers, an alternative was needed.

In 2001 there were very few biological products available and Dudutech was started to develop biological products and create an integrated pest management strategy (IPM). Dudutech pioneered IPM in Kenya, finding and developing local strains of beneficial organisms, and innovative methods of application.

Taking the lead in this area, Dudutech has grown into an organisation employing more than 210 people, producing 17 products, and has successfully developed biological, physical and cultural methods to replace many traditional pesticide treatments.

Identifying that over 60% of insecticides used in flowers were to control the spidermite, Dudutech introduced a voracious predatory mite called Phytoseiulus persimilis to reduce the need for mite control pesticides. At Finlay Flowers South Africa, Phytoseiulus has reduced the level of synthetic pesticides used to combat spidermites to zero, and all 21 hectares of chrysanthemums are fully under this system. At present 90% of Finlays Horticulture’s farms only use biological methods to control spidermites and 100% of the area is under some form of IPM.

Recognising that a healthy soil grows a healthy plant, Dudutech has developed a wide range of beneficial soil organisms that are used on all Finlays Horticulture Farms. This has resulted in a further reduction in synthetic pesticide and fertilizer use, together with increasing soil biodiversity in line with the Finlays’ motto of long term sustainability.

A great example of ‘Environmentally Intelligent Farming’ in action!

The impetus of ‘hot spot treatment’ approach to bio-control in ornamentals

Posted by

The primary goal of bio-control is to optimize pest management in an economically sound, socially acceptable and environmentally friendly manner. Contrary to the initial perception that bio-control was optional and only applied to suppliers accessing certain direct markets in Europe, the past decade has seen a steady growth of bio-control across the Kenyan horticultural industry resulting in massive reduction in pesticide inputs. While stricter local and international regulation of pesticides have certainly played a part in this current state of affairs, greater flexibility and practicability of bio-control on the day to day farm operations are equally important.

Hot spot

IPM practitioners must continuously innovate and adopt specific techniques to judiciously manage pests in a sustainable way. One of the techniques gaining immense popularity is hot spot treatment. A hot spot is an unusual pressure point with relatively higher pest population in relation to homogeneity of its distribution on a crop. Hot spot treatment has been singled out as one of the viable methods of managing costs, reducing pesticide residues levels, countering secondary pests (e.g. mealybugs) outbreaks, managing resistance and ultimately producing quality flowers free of pests and diseases.

Dudutech pioneered this technique in partnership with DANIDA scientists in a study done in one of the Kenyan major horticultural farms. In the greenhouses where hot spot application of PHYTOTECH® (Phytosieulus persimilis) were done to target red spider mites, quicker control was achieved with fewer numbers of the bio-control agents (Phytosieulus spp) introduced compared to where blanket applications of the same were done. It was also noted that mortality due to sprays targeting other pests was minimal as the treated spots can be avoided. Another benefit observed was in the management of other pests especially mealybugs. Mealybugs share the same host niche as red spider mites in relation to crop canopy and have recently emerged as one of the most difficult pests to manage due to their complex physical characteristics. Growers have the option of spot spraying mealybug spots with their products of choice continuously without fear of suspending or affecting their bio-logical control programme unlike the blanket sprays.


On a number of field trials done in different flower growing regions in Kenya, the hot spot concept has successfully wiped out the issue of intermittent use of Phytoseiulus spp due to what is perceived as secondary pest infestation. Growers on massive hacterage have also gotten a reprieve due to the quantities applied per area treated against the actual projected blanket treatment. This has resulted into unusual demand for Biological control agents and eroded the element of cost. Another hidden benefit related to this concept is the opportunity to integrate other biological control agents with minimal cost and greater benefits. In conclusion, I can assure growers that with the adoption of the hot spot approach, one can effectively achieve satisfactory pest control saving up to 40-60% of their IPM budget. Patience, commitment, trust, precise scouting and the will to invest remain the key pillars of a successful IPM programme.
