Evaluation of neemark and nimbecidine for management of root-knot nematode, Meloidogyne incognita in Okra Sharma H.K., Singh R.V., Chawla Gautam Division of Nematology, Indian Agricultural Research Institute, New Delhi. Abstract 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. Top Key words Neemark, Nimbecidine,M. incognita, management, Hostathion, okra. Top | | |
