Abstract
3 strains of antagonistic fungus and 2 pathogens of seedling damping-off were antagonistic cultured by PDA medium,the suppressed rate and the relative antagonistic effect were counted.The results showed that Trichoderma viride,Trichoderma citrinoviridevs and Chaetomium globosum had antagonistic effect on Fusarium oxysporum and Fusarium solani.Trichoderma citrinoviridevs had the best antagonistic effect on Fusarium oxysporum.Trichoderma viride had the best antagonistic effect on Fusarium solani.
