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.

EZYFLOW GYPSUM

EZYFLOW GYPSUM is a liquid suspension of technical grade Calcium and Sulphur applied to improve your soil structure by reducing sodium build-up and increasing Calcium levels in the soil. With an approximate particle size of 2 microns it can be used in fertigation down the drip line and also as a foliar.

ROLE OF GYPSUM

Gypsum is one of those rare materials that perform in all three categories of soil treatment: an amendment, conditioner, and fertilizer.

Gypsum can help create favorable soil by lowering EC, as a high EC value of soil is undesired for the crop growth. High EC of soil can be due to fertilizer application as well as weathering of soil minerals. Gypsum, being readily soluble, results in proper buffered solute concentration (EC) in soil to maintain soil in a flocculated state.

Calcium is essential to the biochemical mechanisms by which most plants nutrients are absorbed by roots. Without adequate Calcium, uptake mechanisms would fail. In soils with unfavorable Calcium Magnesium ratios, such as serpentine soils, Gypsum can create a more favorable ratio.

Gypsum is very useful for improving the textural and drainage properties of heavy (clay) soils. Gypsum is also an excellent calcium and sulphur fertiliser. Its special benefits are that horticultural Gypsum is fast acting and pH neutral (contrasting with other Calcium fertilisers that are slower and either raise or lower soil pH).

Gypsum provides Calcium, which flocculate clays in acid and alkaline soil. A flocculated clay forms friable soil with improved soil structure and tilth. It also allows for deeper, healthier root development and water penetration. Gypsum when applied to sodic soil reduces the levels of exchangeable sodium resulting in increased water retention. Gypsum is another source of Calcium responsible for the binding of soil organic matter to clay and gives stability to soil aggregates. Gypsum can help keep clay particles from adhering to roots, bulbs and tubers of crops like potato, carrots, garlic and beets.

BENFITS OF USING GYPSUM

Liquid Gypsum is much easier to handle and apply via boom spray, drip systems, overhead irrigation and aerial applications compared to the spreading of bulk Gypsum.

Natural Gypsum has unique chemistry properties. Gypsum also known as Calcium Sulphate will react very quickly with Sodium to form Sodium Sulphate, and leach from the soil profile quickly. Gypsum is particularly fast acting due to its approximate 2 micron particle size.

Great source of Calcium and Sulphur for plant nutrition.

Gypsum has an approximate particle size of only 2 microns and can be used in fertigation down the drip line and also as a foliar.

Gypsum is a natural Gypsum and is ideal to reduce Sodium in high pH soils.
