Abstract:
Tomato (Solanum esculentum Mill) is related to the family Solanaceae, it is an major vegetable crop and grown globally. It is suitable host for root-knot nematode (Meloidogyne javanica). Examination the efficacy of bio-agents (viz., Trichoderma asperellum, T. harzianum, Verticillium lecanii, Metarhizium anisopliae and Bacillus subtilis) against M. javanica in @ 3 gm/ kg soil in field condition. Experimental results revealed that the bio-agents are increased the plant growth parameter and reduced the nematode reproduction as compared to control. Among the tested bio-agents T. harzianum @ 3 gm/ kg soil was found most effective treatment followed by Bacillus subtilis and Metarhizium anisopliae. All bio-agents enhance plant growth parameter with in reducing nematode population in field condition.
