The intention for this experiment is to investigate on standard module for the management of root knot nematode, Meloidogyne incognita infected with tomato. The highest reduction in soil and root population (241.26 and 212.38) of root knot nematode, M. incognita was observed in P. lilacinus (root dip) +T. viride (2 kg/ha) + Marigold intercrop treated plot at time of harvest. The control plot which was found to be maximum population of nematodes in soil and root respectively 1252.54 and 1224.88. Significant reduction in root knot index was observed in the treatment with P. lilacinus (root dip) + T. viride (2 kg/ha)+ Marigold intercropped plot was recorded 1.2 per cent. The roots in untreated control recorded the highest lesion index of 5.00.
