Trichoderma is one of the common fungal biocontrol agents being used worldwide for efficient management of various foliar and soil borne plant pathogens. Unlike chemicals, the establishment of these biocontrol agents in the targeted niche requires support even after their application. Two Trichoderma species (Isolate 2 and Isolate 5) were isolated from paddy and groundnut rhizospheres respectively. These two isolates were the two most vigorous ones among all the seven Trichoderma isolates obtained from different crop rhizospheres on the basis of their growth in different media and their inhibitory effects on two potential soil borne pathogens namely Rhizoctonia solani and Sclerotium rolfsii as observed in dual culture experiment.
