Interaction studies between vesicular-arbuscular mycorrhizal fungus Glomus mosseae and Macrophomina phaseolina in mungbean revealed that mycorrhizal inoculation significantly restricted the spread of the pathogen in host root tissues. Disease incidence was reduced from 77.9 per cent in pathogen-inoculated to 13.3 per cent in mycorrhiza + pathogen inoculated plants. Dual inoculation with mycorrhizal endophyte and the pathogen also resulted in increased total dry matter .production, nitrogen, phosphorus and potassium contents of such plants as compared to pathogen-inoculated plants.
