The cadusafos (Rugby registered ) showed strong nematicidal property in lab experiment and greenhouse trail. Cadusafos 1%, 0.5% and 0.25% was tested in egg hatching, juveniles mortality and invasion and development of root knot nematodes Melodigyne incognita (Kofoid and White) Chitwood in tomato to (Solanum lycopersicum L.). Cadusafos 1% was found to be effective in egg inhibition of Meloidogyne incognita. Cadusafos (Rugby registered ) 1% showed 100% while 0.5% and 0.25% showed 72% and 57.3% mortality of juveniles, respectively. Mortality of juveniles increased with increased exposure time and concentration. Invasion, development and reproduction of root knot nematode were evaluated on tomato crop. Data was recorded after 7, 17 and 35 days to observe the penetration and development stages including vermiform, swollen, sausage stage, immature females, adult females and egg masses of M. incognita. Maximum reduction of M. incognita was observed when soil was treated with Cadusafos (Rugby registered ) 1%. Most effective concentration of cadusafos determined by above experiments was used to assess its effect as protective and curative. Root knot nematode population was reduced when cadusafos was applied as protective application.
