Root knot disease caused by M.incognita is a matter of great concern because this species affects several economically important crop plants. Okra is a very important crop by nutrition and health wise. In the present study the application of various parts of neem (seeds, leaves) altered the physiology of host plant and developed the strong defensive mechanism of the root against nematodes.so the use of neem products stimulated and change the physiology of plant cells and tissue to repel the nematode parasite. Extracts of fresh greens leaves, showed max. Reduction in egg hatching and cause great mortality of juveniles and followed by fresh green seed and dry seed extracts. In pot conditions the powder of fresh seed showed highest plant growth and reduction in root knot formation and followed by fresh leaves and dry seed powder.
