The present study was carried out to evaluate the effect of rocket-salad leaf extracts on the development of root knot nematode (Meloidogyne incognita) in lentil (Lens culinaris L.). The treatment used were seed treatment with leal extract,and as soil treatment with leaf exteact in combination with oil cakes, leaves of neem and castor. The study revealed that seed treatment with different concentration of rocket-salad extract for different duration caused significant reduction in root-knot development alongwith improvement in root nodulation, plant growth and chlorophyll content of lentil cv. K-75. However, maximum inhibition in the root-knot development was observed in plants from seeds soaked in ‘S’ concentration of rocket-salad leaf extract for 24h duration followed by plants raised from seeds soaked in S/10 concentration of rocket-salad leaf extract. Combined application of leaf extact as seed treatment along with soil amendment with oil cakes and leaves of neem in clay soils under pot culture conditions also resulted in significant reduction in the root-knot development floowed by improvement in root-nodulation, plant growth and chlorophyll contents in cv. K-75. However, maximum inhibition in root-knot development and improvement in root nodulation, plant growth and chlorophyll content was observed in neem cake treated plants grown from seeds soaked in ‘S’ concentration of rocket-salad extract followed by castor cake, neem leaf and castor leaf treated plants respectively.
