Sustainable Management of Root- Knot Nematode (Meloidogyne javanica) on Brinjal

Abstract

Brinjal (Solanum melongena) is an important Solanaceae family vegetable, which is grown all around the world. It is affected by various fungal, bacterial, viral, nematode diseases but it is a major host for root-knot nematode, Meloidogyne javanica. Hence, for effective management of root-knot nematode experiment was conducted in field condition using the culture filtrate (3gm/kg soil) of bio-agents (viz., Trichoderma viride, Trichoderma harzianum, Purpureocillium lilacinum, Pochonia chlamydosporia and Pseudomonas fluorescens). The findings of the experiments revealed that, when compared to the control, all of the tested bio-agents considerably improved plant development characteristics and decreased nematode populations. Among the tested bio-agents T. viride was found most effective treatment with improve plant growth characters as well as in reducing nematode population over other treatment in field condition.
