Abstract

Trichoderma viride Pers. Ex. Fries and Pseudomonas fluorescens Migula effectively inhibited the growth of Pythium aphanidermatum. Seed treatment with talc based formulation of T. viride (4g/kg) + P. fluorescens (5g/kg) recorded the maximum germination (92.3%), shoot length (4.45cm), ischolar_main length (13.50cm), dry matter production (6.77 mg) and vigour index (1655.67) compared to the minimum in control.

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.
