Tomato (Solanumlycopersicum L.) is one of the most important vegetable cropin the world. Various obstacles are existingwith this cropcultivation, among them root knot nematode,Meloidogyne incognitarecognized as a major path-ogen of tomato. The complete elimination of M. incognitafromthe soil is very difficult because of its polyphagous nature. Although,different methods are employed to manage this nematode, however, biological control has become a good alternative to the chemical nematicides. Antagonistic microorganisms are appropriate for controlling nematodes still require progressive investigation. Hence,present study on the biologicalactivity of the different concentrations of mixer of crude secondary metabolitesof the various fungal bioagents againston egg hatching, M. incognita(J2) mortal-ity in vitro as well asin planta were evaluated. Plant growth promoting activities were also recorded. Among the tested fungal bioagentsV. lecanii, F. chlamydosporum andA. niger were found promising in vitroas well asin planta studies while M. anisopliaeand A. nigerwas found promising to inhibit the egg hatchingunder in vitro study. It is concluded thatV. lecanii, F. chlamydosporum andA. nigerhave high antagonistic/nematicidalas well as good plant growth pro-motion activities. These promising fungal biocontrol agents can be considering for evaluation on a larger scale in field.
