Effect of Seed Soaking and Foliar Spray with Carbosulfan on Root-Knot Nematode, Meloidogyne incognita Infecting Round Melon

The root-knot nematode, Meloidogyne incognita is a serious pest of vegetables. An attempt was made the management of root-knot nematode by using varied applications (soil application, seed soaking and foliar spray) of chemicals i.e. carbofuran 3G and carbosulfan in round melon. The combination of seed soaking + foliar spray (@1000 ppm) with half recommended dose of carbofuran 3G (1.0 kg a.i./ha), gave highest crop yield (84.44 q/ha) and reduced the number of galls per plant (9.67) and final nematode population of soil (125.20), followed by carbofuran 3G @ 2.0 kg a.i./ha (treated check) with yield-71.67 q/ha, number of galls/plant (12.80) and final nematode population of soil (135.50). All the treatments showed higher crop yield, reduced number of galls per plant and final nematode population of soil as compared to untreated control.
