In India the potential of Trichoderma viride Pers: ex.Fr. in managing soil-borne pathogens has been well demonstrated in many crop diseases like seedling diseases of cotton (Ramakrishnan and Jeyarajan, 1986), ischolar_main rot of soybean (Jharia and Khare, 1986), and ischolar_main rot of cowpea (Alagarsamy and Sivaprakasam, 1988). Jeyarajan et al. (1994) developed a talc based powder formulation of T. viride which is being used as a carrier for seed treatment. This formulation contained 2.8 X 108 CFU/g of powder. The present study was undertaken to standardize the exact inoculum level required for the management of ischolar_main rot of urdbean.

Abstract


In India the potential of Trichoderma viride Pers: ex.Fr. in managing soil-borne pathogens has been well demonstrated in many crop diseases like seedling diseases of cotton (Ramakrishnan and Jeyarajan, 1986), ischolar_main rot of soybean (Jharia and Khare, 1986), and ischolar_main rot of cowpea (Alagarsamy and Sivaprakasam, 1988). Jeyarajan et al. (1994) developed a talc based powder formulation of T. viride which is being used as a carrier for seed treatment. This formulation contained 2.8 X 108 CFU/g of powder. The present study was undertaken to standardize the exact inoculum level required for the management of ischolar_main rot of urdbean.
