What is Trichoderma viride used for?

Trichoderma viride is used as a biological fungicide for managing seed- and soil-borne fungal diseases. It helps suppress pathogens associated with root rot, damping-off, wilt, brown rot, charcoal rot, and similar diseases caused by fungi such as Pythium, Phytophthora, Fusarium, Rhizoctonia, and Alternaria.

How do I apply Trichoderma to my plants?

Trichoderma viride can be applied in several ways depending on the crop and growth stage. It can be used as a seed treatment, soil application, soil drench, nursery treatment, root dip, or through drip irrigation. For best results, apply it near the seed or root zone where early root colonization is needed.

Can we spray Trichoderma viride on plants?

Trichoderma viride is mainly used for seed, soil, nursery, and root-zone applications because it is most effective when it colonizes the rhizosphere. Foliar spraying should only be done if the product label specifically allows it. For soil-borne diseases, root-zone application is usually the preferred method.

How long does Trichoderma last in soil?

The persistence of Trichoderma viride in soil depends on soil moisture, temperature, organic matter, pH, microbial competition, and crop conditions. Under favourable conditions, it can colonize the root zone and remain active for several weeks to months. Reapplication may be needed depending on crop cycle, disease pressure, and field conditions.

Is Trichoderma mold harmful to humans?

Trichoderma viride is widely used in agriculture as a beneficial biological control fungus and is generally considered safe when handled according to label directions. However, as with any microbial powder or biological product, users should avoid inhaling dust and should prevent contact with eyes, open wounds, and sensitive skin. Wearing gloves, protective clothing, and a dust mask during handling is recommended.

Which crops can Trichoderma viride be used on?

Trichoderma viride can be used on a wide range of crops, including cereals, pulses, oilseeds, vegetables, fruits, plantation crops, spices, flowers, medicinal crops, aromatic crops, orchards, and ornamentals.

Can Trichoderma viride be used through drip irrigation?

Yes. Trichoderma viride can be applied through drip irrigation when properly mixed and filtered. The product should be mixed thoroughly in water, allowed to settle if needed, and the supernatant can be fed through the drip system to deliver the beneficial fungus into the root zone.

Can Trichoderma viride be mixed with fertilizers or pesticides?

Trichoderma viride can generally be used with many organic fertilizers, composts, manures, and some biological inputs. Avoid mixing directly with chemical fungicides unless compatibility has been confirmed. If fungicides are used, keep a suitable application gap to avoid reducing the viability of the beneficial fungus.

What is the shelf life of Trichoderma viride?

The product has a shelf life of 24 months from the date of manufacture when stored properly in a cool, dry place at room temperature.

Is Trichoderma viride suitable for mushroom farming?

No. Trichoderma viride should not be used in mushroom farming because Trichoderma species can cause disease problems in mushroom production systems.
