Management approaches for root-knot nematode in Onion

An assessment of management tactics on the root-knot nematode, Meloidogyne incognita infesting onion seedlings indicated that integrated treatments with solarization, marigold intercrop, neem leaf mulch, neem cake amendment, azadirachtin and/or minimal amount of carbofuran, were effective in reducing nematode population, egg density in host roots, fecundity of nematode, root-knot frequency and infection in plants. Solo treatment with azadirachtin was effective in suppressing nematode population and recorded crop yields at par with carbofuran.
