Effect on Hatching and Mortality of Root-knot Nematode (Meloidogyne javanica) by Bio-agents

Investigations were carried out in vitro condition to evaluate the antagonistic effect of fungal and bacterial bio-agents. For effective management of root-knot nematode experiment was conducted in laboratory condition using the culture filtrate (5, 10 and 20 percent concentrate) of bio-agents (viz., Trichoderma viride, Trichoderma harzianum, Purpureocillium lilacinum, Pochonia chlamydosporia and Pseudomonas fluorescens). Experimental results showed that all the tested bio-agents significantly reduced the percent hatched juveniles and increased the percent mortality of juveniles. Among the tested bio-agents T. viride was found most effective treatment with minimum percent hatched juveniles and maximum percent mortality on eggs and juveniles of Meloidogyne javanica

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

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
