Role of Oil Cakes and Pochonia chlamydosporia for the Management of Meloidogyne javanica Attacking Solanum melongena L.

A pot experiment was conducted to evaluate the efficacy of Pochonia chlamydosporia, oil cakes of neem, mustard and cotton and nematicide (carbofuran) in the management of root knot nematode, Meloidogyne javanica infecting brinjal under glasshouse conditions.All the treatments were effectively suppressed the nematode population and kept the infection at significantly low levels.Among oilcakes individual treatment of neem was more effective than other oil cakes in controlling M. javanica, whereas among combined treatment, neem cake+P.chlamydosporia was more effective in the management of M. javanica followed by mustard cake+P.chlamydosporia and cotton cake+P.chlamydosporia.However, the efficacy of P. chlamydosporia increased in the presence of oilcakes.Oilcakes when combined with nematicide (carbofuran) showed best results in terms of plant growth parameters, reduce root knot diseases and nematode multiplication after combining with P. chlamydosporia.These organic amendments are capable of producing secondary metabolites, which have an allelopathic effect and develop resistance in plants.This approach is non hazardous, cheaper and easily available to the farmers.
