Antagonistic Effect of Trichoderma viride against Pathogenic Fungi Fusarium oxysporum f sp lycopersici (FOL) and on Alternaria alternata

The study was conducted to know the Antagonistic effect of T. viride on F. oxysporum f sp lycopersici (FOL) and Alternaria alternata. A 7 days old culture of T. viride and pathogenic fungi placed aseptically at periphery of the Petri plate containing the PDA medium. And control was also maintained, after 5 and 6 days of incubation period the experimental results showed 90.4 % inhibition in the growth of FOL and 93 % inhibition in the growth of A. alternata in comparison with the control.
