Abstract

Four Triehodenna isolates were tested for in vitro their antagonistic potential against safflower wilt causing pathogens Fusarium oxysporllnl f. sp. earthami and Macrophomina phaseolilla. Trichoderma viride (PDBC TV 32) and T. harzianum (POne TH 10) were effective against both the pathogens. Trichoderma viride, isolated from the Fllsarium wilt sick plot in Tandur was effective only against M. phaseolin a, while F. oxysporllm f. sp. earlhami had inhihitory effect on sporulation of T. viride.
