Abstract
Studies on the effect of nanocomposite on penetration and development of Meloidogyne incognita on okra revealed that the penetration of nematode started within 24 hours of inoculation in all the treatments and inoculated control (Nematode only). The seeds treated with AgNP @ 50 ppm + ZnONP @ 50 ppm and treatment with carbofuran @ 1.5 g/pot were found to be most effective in reducing J2 penetration, number of galls per root system, eggmasses per root system, final nematode population in soil and delayed the development of Meloidogyne incognita as compared to the treatments with ZnONP @ 100 ppm, AgNP @ 100 ppm and inoculated control (Nematode only).
