Capsicum seedlings are highly susceptible to a number of viral, bacterial, fungal and pest diseases during nursery stage and after transplanting into field. Keeping in view the above information, the aim of the present investigation was to select the efficient AM fungi for their use in nurseries as biocontrol agent against the fusarium wilt of Capsicum annuum. After 50 days, it was observed that all the treated plant showed less disease incidence as compared to control. The quadruple inoculation i.e. G. mosseae + A. laevis + T. harzianum + F. oxysporum showed the maximum shoot height, root length fresh and dry shoot biomass and fresh root biomass as compared to all treated and control plants. Percent mycorrhizal root colonization and spore number was found to be maximum in double inoculated plants of A. laevis + F. oxysporum. But all the leaves of the control plants was showed the yellowing and wilt but in treated plant leaves was yellowish green.
