Troucho  : Trichoderma viridae



  • Biological fungicide.

  • Protects germinating seed, roots and emerging shoots from soil borne pathogens.

  • Economical and effective

  • Environment friendly.

  • Contains vigorous antagonists of plant pathogens based on mycoparasite Trichoderma.

Ideal for organic farming and export oriented crops. Troucho is a fine powder containing minimum 2 x spores and conidia of mycoparasitic fungi Trichoderma viridae per gram, which when introduced along-with seeds root zone protect the seedlings from attack by soil borne pathogens and promote healthy growth in early stages of crop.

Trichoderma organisms in Troucho  grow very fast. Vigorous growth overshadows the pathogenic fungi, who are overpowered and prevented from infecting the plants. Before pathogens attempt infection via germinating seeds or roots they can be suppressed and controlled with this natural method.

Mode of action of Troucho : Growing roots are protected from attacking pathogenic organisms such as
Rhizoctonia, Pythium, Fusarium and Sclerotium by the introduction of beneficial mycoparasitic competitors having aggressive nature. Trichoderma viridae in Troucho is parasitic to these plant pathogens. Mycelia grow and coil around hyphae of host (pathogenic) fungi when seeds are treated with Troucho. Penetration of host mycelia may or may not occur, but susceptible hyphae become vacuolated, collapse and finally disintegrate. Troucho produces cellulase, glucanase and other enzymes which have power to dissolve the hyphae of invading mycelia of fungi, thus reducing their virulence and the susceptible plants are protected.

It is effective as a seed treatment with and without chemical fungicides. It colonizes roots, increases root mass and health, and consequently provides yield increases, which chemical fungicides applied at reasonable rates cannot do. An effective method of use is to use the friendly fungus in conjunction with chemical fungicides. The chemicals provide good short-term seed protection, whereas this beneficial fungus provides long-term root protection. As a consequence, yields frequently are increased over use of the chemical alone.

Following diseases can be controlled by use of Troucho
1) Gram : Collar rot of gram caused by Sclerotium rolfsii, dry rot caused by
Macrophomina phaseoli., root rot caused by Pellicularia filamentosa , stem rot caused by Sclerotonia scleretiorum can be effectively controlled by seed treatment @ 4 gms of Troucho.
2) Pepper : Root rot caused by
Phytophthora can be controlled by soil drench of Troucho @ 0.5 % solution.
3) Groundnut : Collar rot caused by
Pellicularia rolfsii, root rot caused by Pellicularia filamentosa, dry root rot caused by Macrophomina phaseoli can be conrolled by treatment of seeds with 4 grams per kg of nuts.
4) Wheat : Loose smut caused by
Ustilago segetum tritici is a common disease which can be controlled by applying 3 gms of Troucho per kg of seeds . Even karnal bunt disease teliophores are reduced by treatment with Trichoderma as per reports from ICAR.
5) Potato : Charcoal rot caused by
Macrophomina phaseoli and black surf caused by Rhizoctonia solani can be controlled by dipping potato tubers in 0.5 % solution of Troucho. i.e. 50 grams of Troucho per 100 litres of water.
6) Ginger and turmeric: Soft rot caused by
Pythium aphanidermatum and thread blight caused by Pellicularia filamentosa is dramatically reduced by dipping sets in 0.5 % Troucho supension.
7) Peas, matki, mung and urid : Seedling blight caused by
Pythium, dry rot caused by Macrophomina phaseoli can be controlled by treating the seeds with 4 grams of Troucho per kg of seeds.
9) Tomato : Damping off, foot rot caused by Pythium sp.
Phytophthora sp and Pellicularia filamentosa in nursery can be reduced by soil drenching with 0.5 % solution of Troucho in seed bed.
9) Bhindi, onion and other vegetables: Damping off caused by
Pythium and Phytophthora sp. can be reduced by drenching the seed beds with 0.5 % solution of Troucho.
10) Grapes: Botrytis can be reduced by spray of Troucho during late sprays alongwith chemicals for synergistic action.
11) Vegitables : Damping off, root rot , collar rot , wilt Fytopthera , fusarium wilt caused by Pythium sp.
Phytophthora sp and Pellicularia filamentosa in vegitable seeds can be reduced by treating the seed with traucho.  

Compatibility : Troucho Can be applied to seeds treated with metalaxyl or thiram but not mercurials. It can be mixed with chemical fungicides as tank mix.

Packing: 100 grams pouches and 500 kg cartons and can even to supplied in bulk containers.
