Abstract

Root-knot nematode (Meloidogyne incognita) is a catastrophic phytonematode parasite causing enormous losses to wild as well as cultivated crops worldwide. Despite the fact that synthetic nematicides have most significant effect, limiting these phytonematodes but the inherent toxic nature of these chemicals to the environment and human beings have compelled the researchers to think for safe, alternative and eco-friendly substitutes for these chemicals. A pot trial was conducted under the greenhouse condition to evaluate the efficacy of different doses of plant oil cakes against root knot nematode infesting Black gram, Vigna mungo. Root knot nematode, Meloidogyne incognita was found to reduce plant growth and pollen fertility and yield in pulse crop. Among various treatments the Neem cake at 100 g/pot was found most effective in limiting root gall index and enhancing plant growth parameters followed by Mustard cake at 100 g. Neem cake at 50 g/pot, Castor cake at 100 g/pot and Linseed cake at 100 g/pot were statistically at par. Above studies assure an effective and commercially cheap source of controlling root knot nematode in favour of pollution free environment.
