Root-knot nematodes (RKN) have more than 3000 species of potential host range. The majority of the damage to crop plants is caused by Meloidogyne incognita. This experiment investigates the development of standard module for the management of root knot nematode tomato grown under precision farming system; Application of bio nematicides suppressed the pathogenic effect of root knot nematode and significantly reduced gall index and population density of M. incognita in roots and soil. Highest reduction in soil (71.26) and root population (22.38) of root knot nematode, M. incognita was observed in Purpureocillium lilacinum (root dip) + Trichoderma asperellum (2 kg/ha)+ Marigold intercrop treated plot at time of harvest. The control plot recorded maximum population of nematodes in soil and root respectively 1252.54 and 1224.88.The roots in untreated control recorded the highest gall index of 5.00. Significant increase in tomato yield was observed in all the plants treated with biocides. However, highest tomato yield (3.1 Kg/plot) was observed in the treatment with P. lilacinus (root dip) + T. asperellum (2 kg/ha) + Marigold intercrop. It also recorded the highest cost benefit ratio of 1:2.2. While the untreated control plants recorded the lowest yield of 2.1 Kg/plot.
