Pathogenic level of Meloidogyne incognita was calculated to be 2 J₂/g soil as indicated by the reproduction of the nematode. On the basis of wilt index on pea, 1 g of mycelium mat could produce significantly high index value. The presence of root knot nematode irrespective of the presence of other organism showed reduction in shoot length to a significant manner. However, maximum reduction in shoot length was observed in nematode inoculated one week prior to fungus. Both the organisms suppressed the plant growth characters in general and shoot length in particular. Maximum reduction in nematode population was found to be in nematode alone and nematode followed by fungus inoculation. The wilt index on pea after 50 days was recorded to be 3.5, 4.0 and 4.2 in F + N, F→N and N→F, respectively.
