Fusarium spp. isolated from rhizosphere soils of tomato from Karnataka, Tamil Nadu and Gujarat states of India were tested for their pathogenicity. Among these isolates, six were found non-pathogenic to tomato, red gram, bengal gram, groundnut, red pepper, water melon, castor and banana. These non-pathogenic isolates protected tomato plants when co-inoculated with pathogen isolate under pot culture conditions. Treatment with non-pathogenic Fusarium isolates improved the plant growth parameters (length and weight of ischolar_main and shoot). These non-pathogenic Fusarium isolates can be exploited for the biocontrol of wilt disease.
