Trichoderma viride is a biological fungicide that protects crops from soil - borne plant diseases and foliar diseases caused by pathogenic fungi. Trichoderma kills major root rot fungi: Pythium, Rhizoctonia and Fusarium by mycoparasitism.

Trichoderma viride grows on the surface of roots, where it provides disease control and enhances root growth. It protects all the roots for the whole growing season. Chemical controls protect only the seed where they are applied, and their protection lasts, at most a few weeks.

Mode of Action

Trichoderma viride colonizes maximum space and absorbs maximum nutrients available at the target site and there by control the pathogens by starving them for food and competing for space. It also secrete antifungal metabolites which are antagonistic to the pathogenic fungal species and suppress their growth.

Target Disease

Root rot, root wilt, seedling rot and color rot diseases caused by Botrytis sp and other fungal pathogens.

Crops

Flowers, pulses, Pepper, Fruits.

Method of application:

• Liquid

Soil application: Mix 2 L Trichoderma with 200 kg organic manure(for 1 Acre), keep the mixture under shade with sufficient moisture content (30%) for one week and apply to the soil. Apply 1kg in moist soil/base of trees, 250g in potted plants as prophylactic treatment.

Seed treatment: Mix 10 ml Trichoderma with 1kg seeds before sowing in moist soil to control seed decay, damping off and collar rot diseases. Dry in shade for 30 minutes before planting and sow with in a day.

Foliar spraying: Mix 20 ml Trichoderma in 1L of water and spray on the foliage during evening hours and also drench at the base of plants.

• Powder

Soil application: Mix 20 kg Trichoderma with 200 kg organic manure (for 1 Hectare), keep the mixture under shade with sufficient moisture content (30%) for one week and apply to the soil. Apply 1kg in moist soil/base of trees, 250g in potted plants as prophylactic treatment.

Seed treatment: Mix 25 g Trichoderma with 1kg seeds before sowing in moist soil to control seed decay, damping off and collar rot diseases. Dry in shade for 30 minutes before planting and sow with in a day.

Seedling root dip: Mix 500ml of Trichoderma with 60 L of water. Immerse the seedling roots for 20 minutes before planting.

Seedling root dip: Mix 2 kg of Trichoderma with 50 L of water. Immerse the seedling roots for 10 minutes before planting.

Foliar spraying: Mix 1 kg Trichoderma in 50 L of water and spray on the foliage during evening hours and also drench at the base of plants.

Potted plants: Apply 20g Tichoderma in potted plants in the basin at the time of planting as prophylactic treatment.

Preparation of Trichoderma with Organic Manure

Prepare a mixture of dried cowdung with neem cake in 9:1 ratio (10 kg neem cake in 90 kg dried cowdung). Add 2 kg Trichoderma to this 100 kg mixture, sprinkle required amount of water and mix it well. Make 1 feet heap of this mixture in shade and cover it with sack or polythene sheet. Trichoderma will cover this mixture after one week. Mix it once more by giving

required amount of moisture and cover the heap. This mixture will contain 106 Trichoderma cells.
