Study on Isolation, Effectiveness and Formulation of Native Trichoderma spp. from Jhum, Virgin and Cultivated Land of Nagaland

Ten Trichoderma isolates named as isolate1 to isolate 10, were isolated from different soil samples collected virgin, Jhum, cultivated, and fallow land of Medziphema block Nagaland state by serial dilution agar plate method on selective medium (TSM). All the tested against Fusarium solani Sclerotium rolfsii dual culture method. highly effective both pathogens with 83-93 percent 72-89 per cent growth inhibition rolfsii, respectively. Among isolates, was observed most effective; therefore, it mass multiplied in Potato Dextrose Broth formulated talc powder. The colony forming units counted thrice determine number viable conidia product; first counting done same day formulation, second one month, last six months after formulation. It that decreased 13 × 106 c.f.u. 5.66 storage initial formulation which indicates even storage, 1 using powder still contained good conidia. Thus, overall results obtained present work, can be concluded spp. a ubiquitous fungus an biological control agent paramount components integrated disease management.
