Leaf extracts of two plants such as Murraya koenigii L. Spreng and Vitex negundo L. were used as bare-root dip treatment for the management of phytonematode, Rotylenchulus reniformis infecting Okra (Abelmoschus esculentus (L.) Moench ) cv. “Pusa Sawani” and Cowpea (Vigna unguiculata (L.) Walp). cv.‘Pusa Komal’ Plants. Significant reduction was observed in the nematodes multiplication of R. reniformis on the experimental plants. Leaf extracts of Murraya caused relatively higher inhibition in nematode multiplication than Vitex. Improvement in plant growth was noted. The efficacy of root-dip treatment with respect to improvement in plant weight and reduction in disease incidence increased with the increase in concentration of leaf extracts and root dip duration.
Key words: Bare-root dip treatment, cowpea, Murraya koenigii, leaf extracts, phytonematode, Vitex negundo.
