This study has demonstrated that biological management of wilt, root-knot and disease complex can be successfully achieved with the application of the three developed biopesticides viz., Biowilt-X, Bionem-X and Biocomp-X and gives special focus on their deployment on a commercial scale. The used strians of biocontrol agents were found highly tolerant to the fungicides such as carbendazim (bavistin 50 WP), mancozeb (dithane M-45 75 WP), metalaxyl (apron 35 SD), captan (captaf 50 WP) and thiram (TMTD 75 WP) commonly used by farmers in India. Hence pesticidal contamination in soil...
