ABSTRACT
Ten Trichoderma spp. isolates were screened for their antagonistic potential against Sclerotim rolfsii (S.r-9) causing stem rot disease in groundnut isolated from soil. In dual culture technique the isolate GRT-1 was found more effective among the all isolates due to its complete over growth on S. rolfsii. Screened was done by the two intervals i.e fourth day and eighth day after inoculation. In dual culture, among ten Trichoderma spp. isolates tested, by eighth day, Trichoderma isolate GRT-1 showed over growth of 42.00 mm with sporulation on S. rolfsii (S.r-9) was found more effective among the entire test isolates due to its complete over growth on S. rolfsii (S.r-9)
Key words: Trichoderma spp., Sclerotim rolfsii, Dual culture
