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.
