Arbuscular Mycorrhizal Fungi benefits plants by improving the uptake of phosphate and other nutrients from soil and also increases the disease tolerance to the host plant. The fungal pathogens cause huge loss to vegetable crops when infected. In order to overcome this problem, the influence of AMF in the control of fungal plant pathogens is studied. AMF, Glomus sp. was isolated from the rhizosphere soil of tomato plants. The wilt pathogen, Fusarium oxysporum f.sp. lycopersici was cultured from the infected roots of tomato plants. The interaction of AMF and soil borne pathogen was carried out in tomato by in vitro and pot culture experiment using Glomus sp. and wilt causing pathogen, Fusarium oxysporum f.sp. lycopersici. In vitro interaction of AMF root and fungal pathogen resulted in the formation of clearing zone around the root indicating the production of antimicrobial compounds from the mycorrhizal root that arrested the mycelial growth of the fungal pathogen. The pot culture experiment revealed that the pre AMF – post pathogen inoculation to tomato reduced the disease incidence, and increased the plant growth, dry weight, N, P, K content, chlorophyll content and yield of the plant.
