Biopotency of Oilcakes against Meloidogyne incognita Affecting Vigna mungo

Abstract

Root-knot nematode (Meloidogyne incognita) is a catastrophicphytonematodeparasite causing enormous losses to wild as well as cultivated crops worldwide. Despitethe fact that synthetic nematicides have most significant effect, limiting these phytonematodes but theinherent 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 conditions to evaluate the efficacy of different doses of plant oil cakes against root knot nematode infecting 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 @ 100g/pot was found most effective in limiting root gall index and enhancing plant growth parameters followed by Mustard cake @ 100g. Neem cake @ 50g/pot, Castor cake @ 100g/pot and Linseed cake @ 100g/pot were statistically at par. Above studies as surean effective and commercially cheap source of controlling root knot nematode in favour sustainable agriculture and food security.
