Sesamum indicum is well known oil seed crop and rich in protein .The product and byproducts have the tremendous value. Fungal diseases causing infection to the root, foliage and seed decreases the quality and yield. To tackle this problem biological agent is effective and it is ecofriendly does not harmful. so that, for recent investigation Trichoderma viridae as bioagent was selected. Trichoderma viridae act as a potent bio control agent having lytic activity and antagonistic properties against the wide range of the plant pathogenic fungi. Work were initiated with the isolation and identification of antagonistic fungi as well as phytopathogenic fungi by microscopic examination using standard key(Barnet and Hunter).In present study Trichoderma viridae was screened for antifungal activity by dual plate culture method against Alternaria sesamae, Colletotrichum sp,Fusarium oxysporum isolated from oil seed crop Sesamum indicum L. Antagonist i.e. Trichoderma viridae maximally retarded growth of Alternaria sesame, followed by Colletotrichum sp, minimum growth of inhibition shown in Fusarium oxysporum.
