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.

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.

Thrips: Early Detection Is Key!

Posted by

Mastering monitoring tools for improved Thrips control.

By Festus Kilee, John Ogechah and Cory Smit

As more growers around the world face Thrips (Order: Thysanoptera) and the crop challenges they bring, information and understanding have never been more important. Unnoticed Thrips challenges pose a significant threat to growers as their populations can quickly balloon, impacting on crop production, quality and overall cost. In particular, when crops are destined for overseas markets which are typically sensitive to quality and have strict phytosanitary restrictions in place, ignoring this threat may result in significant financial losses when the crop fails to make it to market. Inversely, with Thrips monitoring data available, growers can run timely interventions and target hot-spots. Early detection then translates into reduced spray volumes and reduced crop losses. 

Fortunately, there are well-established methods of tracking and monitoring Thrips populations on crops. By regularly gathering Thrips data using sticky traps, pheromone lures and manual observation techniques, growers can get a head start and inform their control decisions, mitigate crop losses and save money.

Methods of early detection

Global crop protection research efforts have resulted in a number of monitoring tools and techniques being developed for use in a farm environment. In this article, we will cover scouting, traps and pheromone lures for Thrips (however, these techniques can be applied to a variety of other flying crop pests.)


Scouting uses visual inspections of the plants to note Thrips presence and pressure. A simple technique involves counting larvae by gently tapping a sample of the crop onto an A4-sized sheet of white paper, any Thrips which drop to the paper are then counted using a magnifying lens or loupe and recorded.

Sticky traps

Different insect pests are attracted to different colours (wavelengths of light), with yellow and blue so far proving most attractive to crop pests. For example, Western flower thrips (Frankliniella occidentalis) which are most common and difficult to control, particularly favour blue traps over yellow ones.


Fig. 1. Sticktech Blue mode of action.

The colour-tuned material on these traps attracts the pests to an adhesive covered surface, which they then stick to, becoming trapped. Researchers or growers, then collect the data from the traps by counting and identifying the Thrips and other insects caught. This data, when plotted over time, reveals the pest trends for the area in question.

Dudutech has a range of tools for early detection of flying stages:

  • Sticktech – uses blue or yellow sticky cards which are placed between 10 – 15 cm above the plant canopy.
  • Optiroll – uses blue or yellow sticky rolls which are hung between poles and positioned 10 – 15 cm above the plant canopy.


These are synthetic chemical signals which mimic natural insect pheromones to attract the target to a trap. Since these are based on nature, these pheromone lures are species-specific. However, there are a wide variety of pheromone lures available for a number of important crop pests.

What other benefits?

Beyond the scope of pure observation, these sticky traps are also a valuable part of successful IPM practices. When researchers (Kirk and Sampson, 2013) looked at the potential economic returns gained from using traps and pheromones as part of a crop protection strategy for strawberries, they revealed a quality effect on the overall yield. The charts below illustrate their findings:

Chart 1. Quality effect of sticky traps in strawberries (Kirk and Sampson, 2013).

In summary, Kirk and Sampson (2013) found that trapping significantly increased the proportion of Class 1 fruit, and pheromones further improved their efficacy. These measures would be particularly suited to growers who wish to optimise their yield quality and those whose crops undergo strict quality checks before entering the market. 

When used together, these tools can provide a thorough picture of the current and future trends in Thrips challenges on a farm. Having these measures in place early could provide the vital data farmers need to make informed and well-timed crop protection decisions, reducing cost and improving crop quality.

“Dudutech recycles about 577kgs of plastic per week”

“Having the preservation of the environment at our core, we continually ask ourselves what more we can do to help build a sustainable future.” – Barnaba Rotich

By Cory Smit, Dudutech Marketing


As hygiene supervisor at Dudutech, Antony Matete oversees the recycling of 10,500 product bottles and 200 high-density boxes per week, helping to mitigate the environmental impact of getting our products to the fields where they do their work. Once cleaned and all microbial residues have been removed, the materials are reintegrated into the packaging processing line for use on future orders.

The recycling scheme aims to capture and process at least 70% of all the bottles boxes delivered within Kenya but often exceeds this. According to Eric Langat, Dudutech Logistics and Packaging manager, “the delivery drivers who collect the returned materials typically bring back between 5-10k bottles per week from customers.” In numbers, the scheme reintegrates at least 577kgs of plastic per week or ~30t per year.

By using high-quality HDPE bottles and shipping boxes for the majority of our products, the standards are designed with recycling in mind, ensuring that the materials are durable, easy to clean and can be washed for reuse many times.

To ramp-up throughput, we commissioned an automatic bottle washing machine in January 2020, enabling Anthony and his team to process up to 200 bottles in 5 mins. The high-pressure machine thoroughly cleans the bottles of any microbial residues, dust and contaminants.

Barnaba Rotich, Head of Commercial at Dudutech said, “as a business in the 21st century, it is imperative that we work towards the long term sustainability aspects of our business by taking care of the short term… Having the preservation of the environment at our core, we continually ask ourselves what more we can do to help build a sustainable future. Our mission often takes us to the smallest common denominators of each part of the business, allowing the adjustments, such as the recycling scheme, to have a deep impact on efficiency without compromising quality.”

Meet the new Technical Product Team

By: Cory Smit – Dudutech Marketing and Communications

Dudutech is excited to announce the introduction of the new Technical Product Team, John Ogechah and George Mala. The newly created role comes as part of a commitment to continuous improvement and aims at connecting all arms of the business to deliver insights, facilitate feedback and provide support to the Technical Liaison Officers (TLOs) who work directly with growers.

John Ogechah, Dudutech Technical Product Manager, during an in-field instructional session.

John Ogechah, Technical Product Manager (formerly Dudutech Training Manager), is an entomologist with extensive in-field experience and a strong drive for agricultural education. 

“I have spent the last 15 years of my fulfilling professional life empowering farmers with knowledge and skills on sustainable agriculture to survive and grow in the dynamic agricultural landscape.” said John. “The Product Management role is another exciting opportunity to devise solutions to farmers’ problems by steering the vision, design and execution of products that are truly good for the people, planet and profit,” he continued. 

George Mala, Dudutech Technical Product Lead, at the Dudutech Trial Site.

George Mala, who also shifted from the Training department, is an IPM evangelist and horticulturalist with over 20 years’ experience in the industry, 13 of which have been at Dudutech. 

According to George, “unlike conventional crop protection products, biopesticides are unique in that their users require closer technical support.” He went on to say, “this role is exciting for me in that it builds on my experience in on-farm training and focuses it on providing this support to growers.”

The customer-facing function positions John and George as feedback channels between the customers and Dudutech to foster an environment for open discourse and to create awareness for and provide information on IPM in the form of training sessions. Working side-by-side with the TLOs, who have an in-depth understanding of each farm they look after, the TPLs bring new synergies into action to advise on how to drive the performance of their IPM strategy.

A key role of the TPLs is to manage extensive agronomical trials to gather a rich data set on performance, compatibility and best practices for Dudutech’s range of current and upcoming products. John and George will use the data they develop to inform improvements in production, technical operations, training and product materials.

According to Tom Mason, Dudutech MD, “the technical product roles build a robust communication channel between the infield customer experience and our manufacturing facilities and partners both locally and abroad. This will ensure that product efficacy, correct use, and compatibility with farmers programs are always central to our business practice. Enabling the farmer to maximise the value that Dudutech is able to offer.

“John Ogechah and George Mala are deeply experienced professionals who have supported our customers with technical insight and knowledge, sharing with customers in South Africa, Zimbabwe, Uganda, Kenya and the UK,” Tom said, adding that he is pleased that Dudutech can now “focus their talent and experience in a more product-centric manner.” 

Tom went on to explain that, “Integrated pest management (IPM) is evolving at an incredible pace, horticulture and in turn crops such as avocado, citrus, viticulture and row crops are under further pressure to reduce residue levels in the crop and synthetic chemistry is now more than ever focused on compatibility with biological solutions. At the centre of all this, farmers need to do more with less and to remain competitive the core focus is to boost yields.” 

In memory of Philip Carlton-Smith

Posted by

The Dudutech team is deeply saddened by the passing of Philip Carlton-Smith on 26 March 2020. 

As CEO of Ecospray and IBMA UK Chairman, Philip Carlton-Smith has been a part of the Dudutech community for over 5 years, uniting behind a common cause to promote sustainable agriculture. According to Ecospray’s Chairman, Stephen Falder, Philip had “bravely engaged with an aggressive and serious Cancer for months.” 

Tom Mason, Dudutech MD, who knew Philip personally, said that he was “an incredible business leader, he leaves and powerful and memorable presence in the entire Biological Crop Protection industry that will be sorely missed. I am pleased that we will continue the work that Philip and the entire Ecospray team helped us develop for the East and Southern African markets”.

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

The War on Red Spider Mites

Posted by

Tetranychus urticae – Pic: J. Holopainen

Despite their tiny size, red spider mites (Tetranychus urticae) have a big impact on global agriculture, causing extensive damage to a wide variety of plants and crops and they have a terrifying super-power. These tiny super-pests are potentially resistant to the narrow range of available acceptable pesticides. However, the agriculture industry has minute but powerful weapons to fight the mites – biological controls (or biocontrols).

Biocontrol is a branch of Integrated Pest Management (IPM) on the forefront of scientific advances in long term agricultural sustainability using the pest’s own natural enemies against them while reducing reliance on chemical pesticides which can harm people and the environment.

Dudutech, an IPM company based in Naivasha, Kenya, has over ten years experience in designing and developing biocontrols used in the management of red spider mites in large scale agriculture. In particular, Dudutech has successfully developed two powerful biocontrol products: PHYTOTECH® and AMBLYTECH®.

PHYTOTECH® is a highly targeted biocontrol which deploys the beneficial mite Phytoseiulus persimilis, which actively searches for and feeds on red spider mites in all lifecycle stages. Once PHYTOTECH® has cleared pest, they either leave in search of more food or eventually die off. This makes PHYTOTECH® a precision weapon in the war against red spider mites.

Similarly, AMBLYTECH® is also a natural enemy of red spider mites, but the beneficial mite Amblyseius californicus are able to go for long periods without feeding. Although Amblytech prefer to feed on red spider mites, they also feed on Thrips and nectar. This features allow AMBLYTECH® to be used preventatively, protecting plants from red spider mites over longer periods of time.

When growers use PHYTOTECH® and AMBLYTECH® they harness the power of nature to sustainably protect their crops against red spider mites. Without the harmful chemical pesticides in their growing practices their crops are healthier, pre-harvest intervals are reduced to zero and pesticide resistance is avoided.


Further info:

Red spider mites also known as two-spotted mites, or scientifically as Tetranychus urticae, are arthropods which use their needle-like mouthparts to feed on plant tissue, causing yellowing or greying on leaves. If not brought under control, they can cause plants to completely lose their leaves. When T. urticae feed on flowers brown speckles appear on the petals.

Red spider mites have a lifespan of up to 16 days and peak hatching occurs at around 27°C, developing from an egg into an adult, reaching around 0.4mm long, within 8 days. Each female can lay up to 20 eggs per day – this rate can see their populations balloon within a short time frame.

T. urticae feed on more than 200 different species of plant and are regarded as highly economically important, due to their destructive impact on global agricultural produce.

Zimbabwean authorities approve range of ICM products from Dudutech

Posted by

After a rigorous registration process, Phil Weller, the official distributor of Dudutech products in Zimbabwe, has received the official rubber stamp on a range of pest and crop management solutions. Among the products now available to farmers in Zimbabwe are MYTECH, TRICHOTECH, LECATECH and BEAUVITECH, microbial products used for the management of pests and diseases, and the intelligent chemicals pHusion and Trident used to boost crop development. The country, which has a tradition of commercial agriculture, is set to directly benefit from these innovative products through improved plant health and more sustainable crop and soil practices.

More about the products:

MYTECH contains Paecilomyces lilacinus (F18), a naturally occurring nematode killing fungus used to manage plant parasitic nematodes including Root knot, Cyst, Root lesion, Burrowing and Reniform amongst others.

BEAUVITECH contains spores of Beauveria bassiana J25, a fungus which kills Thrips and whiteflies through an entomopathogenic processes.

LECATECH is a biological insecticide containing Lecanicillium lecanii J27, a naturally occurring specialised entomopathogenic fungus which targets whiteflies.

TRICHOTECH contains spores of Trichoderma asperellum a soil dwelling fungi that is beneficial to plants. The fungus is antagonistic to soil pathogenic fungi and has been used globally for control of soil borne fungal diseases caused by Fusarium spp., Pythium spp. and Rhizoctonia spp. In addition, the strain is known to increase plant vigour.

pHUSION is a foliar feed containing 3-21-23+2% Phosphite + Silicon. The Si in pHUSION stimulates phosphite metabolism within the plant leading to increased root development even during stressful conditions.

TRIDENT is a folliar feed containing Zinc, Copper & Silicon – essential elements for plant health.

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.”

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.

ABIM 2017: The Biggest Biocontrols Gathering – Ever

Posted by

Photo: David Cary, IBMA Executive Director said “We are constantly encouraged by the growth in visitor numbers this is a reflection of the Steering Committee’s continuing commitment to promoting a unique event showcasing innovation, excellence and professionalism in the industry.”

Dudutech was at the biggest gathering of the biocontrol industry ever, held in October this year. Tom Mason (Dudutech MD) and Barnaba Rotich (Dudutech Commercial Manager) were among the record-breaking delegation of 1050 people from over 500 companies at the 12th Annual Biocontrol Industry Meeting (ABIM) held in Basel, Switzerland.

Recent growth in the biocontrols industry correlates to strong growth in organic farming and. According to Lucius Tamm from Research Institute for Organic Agriculture (FiBL), organic farming, despite having boomed by 455% in 17 years from 11 million ha to 50 million ha, provides a smaller market than conventional agriculture. This information hints at the optimism for the future of the industry as biocontrols move closer towards improving mainstream awareness and acceptability.

ABIM 2017 was also a platform for innovation, information and unprecedented face-to-face networking opportunities. The meeting provided an interactive audience of the world’s leading biological technology producers to 69 individual exhibitions and speeches from industry leaders. Tom Mason said the gathering provided a space for “cross pollination of ideas, commercial opportunities and alliances … in a single forum in Basel, Switzerland.”

Tom Mason went on to say, “it’s also an opportunity for members of the International Biological Manufacturers Association (IBMA) to meet and agree upon how this industry association will represent their voice with regulators and the broader industry. Since the formation of the parent association Bio Protection Global (BPG) in 2014 the board of BPG also congregates to discuss the broader global industry challenges and opportunities. As 2018 president of Bio Protection Global I am trying to drive the success of BPG in a similar fashion to the chemical industry association Crop Life International and we hope to make good progress during the course of 2018, alongside Board Chair Rick Melnick the Brand Manager for Vlaent Bioscienes.”
