Abstract :

In the present investigation the biocontrol effect of Trichoderma viride against Fusarium oxysporum on Tomato vegetable crop under nursery experiments. The collected soil sample used to isolate fungal pathogens and antagonistic fungi. Isolated colonies were identified cultural and morphological characters. In this study many type of fungal colonies were identified among the isolate the dominant fungal pathogen and antagonistic fungi were selected. The separated colonies were confirmed as Fusarium sp and Trichoderma viride. To analyse the antagonistic activity of Trichoderma viride against Fusarium sp. using various methods. In this study Trichoderma viride produced good antagonistic activity against Fusarium sp. The biocontrol agent resulted in increase in soil fertility, control of minor pathogens and increase in general health of plants, ultimately leading to an increase in plant metabolism. If enhanced the growth producing stimulating factors.
