Evaluation of neemark and nimbecidine for management of root-knot nematode, Meloidogyne incognita in Okra

Seed soaking of okra (cv pusa sawani) in neemark and nimbecidine @ 1,5 and 10% alone and also combined treatment of neemark and nimbecidine 1 and 5% with hostathion 1% for 2,6 and 24 h period were investigated against root-knot nematode Meloidogyne incognita infecting okra. Significant reduction in number of galls was observed in neemark and nimbecidine 5% with 6 and 24 h soaking. Plant growth improved with rise in concentration of neemark and nimbecidine in 6 h soaking. At 24 h soaking in nimbecidine, 10% negative plant growth was recorded. Hostathion 1% alone was effective for 2,6 and 24 h soaking in reducing the number of galls. Hostathion 1% in combination with neemark, did not exhibit any complementary effect in mitigating the nematode population or plant growth while with nimbecidine some complimentary effect was indicated.
