EFFECT OF A PLANT BASED PRODUCT-'NIMIN' AND SOME PLANT OILS ON NEMATODES

Abstract

Nimin, an industrial product containing neem triterpenes, and oil from castor (Ricinus communis), mustard (Brassica juncea), neem (Azadirachta indica) and rocket-salad (Eruca sativa) significantly suppressed populations of some ecto-parasitic nematodes and reduced the incidence of Meloidogyne incognita on chilli (Capsicum annuum) when applied as bare-root dips. Nimin gave the best results in terms of reduced root-knot incidence and improved plant growth, followed by oils of neem, castor, rocket-salad and mustard. The effect of treatments was related to their concentrations.
