Evaluation of Different Organic Materials as Carrier for Formulated Product of Trichoderma

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.
