MANAGEMENT OF ROOT-KNOT NEMATODE, MELOIDOGYNE INCOGNITA ON GREEN GRAM THROUGH BIOAGENTS

Kshetrimayum Sumita, Deban

Abstract

Investigation carried out to study on efficacy of different bio-agents (Trichoderma viride, T. harzianum, Biofor- pf and neem cake) against root-knot nematode, Meloidogyne incognita in green gram (Vigna radiata) revealed that soil application of neem cake @ 2 tones/ ha significantly increased the shoot length, fresh and dry weight of shoot of green gram, followed by soil application of T. viride @ 2.5 kg/ha as compared to untreated control. Among the different bio-agents, Biofor-pf @ 100 kg/ ha exhibited the best result in reducing the galls, egg masses and final soil nematode population followed by neem cake @ 2 tones/ ha. However, application of Carbofuran @ 1 kg a.i./ha was very effective in reducing the galls, egg masses as well as soil nematode population.
