Troucho
: Trichoderma viridae
IDEAL AGENT FOR COMPOST SEED TREATMENT :
-
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.
