Investigations were carried out on the management of reniform nematode, Rotylenchulus reniformisinfecting okra (Abelmoschus esculentus) by integrating ecofriendly components such as oil cakes viz., neem(Azadirachta indica), castor (Ricinus communis), black mustard (Brassica nigra), sunflower (Helianthus annus) and linseed (Linum usitatissimum) @ 15 g/kg soil and a biocontrol agent Paecilomyces lilacinus @ 1g mycelium + spores/kg soil. The treatments were evaluated individually and in integration against R. reniformis under glasshouse conditions. It was noted that all the treatments quite effectively suppressed the nematode population and kept the infection at significantly low level. Application of P. lilacinus showed better results in improving plant growth and reducing the nematode population build up as compared to oil cake treated plants whereas neem cake gave better results than other oil cakes. However, integration of neem cake with P. lilacinus gave best result causing increased plant growth and reduced population build up of reniform nematode.
