Four locally available organic materials viz., farm yard manure, rice bran, saw dust and wheat bran were evaluated for their suitability as a carrier for a talc based formulation of Trichoderma viride . Mixtures of T. viride and these carriers were applied in soil to control ischolar_main diseases of sunflower. The results revealed that saw dust + T .viride mixture significantly reduced plant mortality caused by ischolar_main pathogens with commensurate increase of achene yield in sunflower.
