Trichoderma usual used as a biological control agent in soil
how about foliar spray Trichoderma to control disease on leaves ?
Hi Loc, There is many paper on this subject, please find these links:
Article Biological control of foliar pathogens by means of Trichoder...
trichoderma are used mainly as soil inoculants for the control of root diseases, but it can be used to control some of the foliar diseases like gray mold, powdery mildews.
Yes, Trichoderma can control many foliar diseases like gray mold, powdery mildews and postharvest decays on different crop species
Trichoderma can secrete many secondary metabolisms useful for inducing the plant defense
Y est, it's possible for certain species.
Il Havel tested thème on Phytophthora infectant and on Botrytis.
Yes of course but concerning some species and strains.
As, T. atroviride and T. asperellum.
Saida! You meet three different problems:
- The interaction between antagonist/pathogen might be highly specific, thus there can not be predicted with high sureness the appropriate control in local area.
- In general, the suspension of conidia of the mentioned species in liquefied starch or inulin - about 0,1-0,5 percen w/v - can be temporarily stabilized with Tween 20 (0,02 % w/v) without loss of vitality. Such watery suspension should be applied within 10 hours after preparation.
- The possible incompatibility with resident microbial consortium associated to host plant to be protected. It is highly advisable to check the presence of local Trichoderma complex in foliage.

True, according several factors. Thank you for your precision.
I Am interested by any project concerning this subject.
Trichoderma viride, T. harzianum and T. virens fungal antagonists commercially available at Microbial Type Culture Collection and Gene Bank (MTCC) chandigarh used for the management of soil borne pathogens by seed treatment and soil application also foliar diseases such as blights, Powdery mildew, Downy mildew are said to controlled when sprayed at cooler temperatures.
In my opinion it can be used as it triggers the expression of host defense genes and enhance the immune response of the host.
