Efficacy of seed dressing with extracts of neem and Persian lilac against Meloidogyne incognita and Rotylenchus reniformis

Abstract

Root-knot and reniform nematodes are among the major nematode pests of vegetables in Northern India. They have been controlled by the soil application of various organic amendments including oil-seed cakes of neem (margosa) (Azadirachta indica A. Juss.). Singh et al. (1980) have claimed significant reduction of root-knot development on tomato by seed dressing with neem cake. In the present study we have tested the feasibility of the use of crude extracts of different parts of neem and an allied species, Persian lilac (bakain) (Melia azedarach L.) as seed dressings against Meloidogyne incognita (Kofoid et White) Chitw. and Rotylenchulus reniformis Linford et Oliveira.
