In vitro Antagonism of Trichoderma viride against Fusarium oxysporum strains

Fusarium oxysporum is a soil borne fungal pathogen that attacks plants through roots at all stages of plant growth, causes major economic losses by inducing necrosis and wilting symptoms. Trichoderma viride tested against Fusarium oxyspoum strains under in vitro conditions. The results revealed that Trichoderma viride showed maximum inhibition 71.00% over Fusarium oxysporum strain (E) and minimum inhibition 62.50% over Fusarium oxysporum strain (D) in dual culture plate technique. Trichoderma viride showed maximum inhibition 45.27% over Fusarium oxysporum strain (E) and minimum inhibition 14.72% over Fusarium oxysporum strain (C) in sealing agar plate method. It is concluded that the T. viride has found to be a potential biocontrol agent against Fusarium oxysporum phytopathogenic strains. It may be therefore a promising ecofriendly bio controlling sources and cost effective for the safe agricultural practices as well as to farmers.
