Bio-agents for management of wilt complex in Tomato by Meloidogyne incognita and Fusarium oxysporum f. sp. lycopersici

Wilt disease caused by Fusarium oxysporum f. sp. lycopersici is limiting factor in tomato production also develops synergistic relationship with Meloidogyne spp. leading to root-knot wilt disease complex which is highly destructive to tomato plants and is characterized by enhanced wilt symptoms. Efficacy of different bio-control agents were evaluated against wilt disease complex developed by M. incognita and F. oxysporum f. sp. lycopersici. To manage the disease complex, bio control agent were used as seed treatment @ 4 g/kg seed as well as added to soil @ 4 g/kg soil. Among bio-control agent, Trichoderma viride was found significantly superior in reduction of nematode population and % disease incidence along with increased in plant growth parameters followed by Paecilomyces lilacinum.
