Experiments were conducted in vitro to assess the nematotoxic effect of some opportunistic fungi on Meloidogyne incognita. Mycoflora isolated from the eggmasses and rhizosphere soil were subjected to ovicidal and larvicidal tests. Among the fungi treated, Paecilomyces lilacinus (PlT1) recorded 72.76% eggmass parasitization followed by P. lilacinus (PlT2) 71.0%. The fungi which were found effective against eggmasses were further evaluated on J2. In case of juveniles, P. lilacinus isolate (PlT1) caused 93% and V. chlamydosporium 84% mortality in cent per cent concentration of fungal filtrate after 72 h exposure period.
