  • Tamil Nadu Agricultural University, Department of Plant Pathology, Coimbatore, 641003, India


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), root rot of soybean (Jharia and Khare, 1986), and root 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 root rot of urdbean.
