Screening of?Trichoderma?Species against Major Soil Borne Fungal Pathogens

摘要

The antagonistic potential of forty four isolates of Trichoderma were evaluated in vitro against the most widely occurring soil borne plant pathogens viz.,?Macrophomina phaseolina, Rhizoctonia solani, Rhizoctonia bataticola?and?Sclerotium rolfsii?to identify the most potential Trichoderma isolate. Maximum growth inhibition of?M. phaseolina?(81.11 %),?R. solani?(82.59 %) and?S. rolfsii?(76.67 %) was recorded by?T. hamatum?where as?T. virens?was most aggressive against?R. bataticola?(68.15 %) in dual culture technique.
