| Abstract: | The biological control effect of Trichoderma kningii on Pyricularia oryzae was stu-died.The culture medium of Trichoderma kningii and the culturing condition was optimized.The results showed that the formula of optimum fermentation culture medium was:500 mL water containing bran 10.0g,corn cob powder 15.0g,(NH4)2SO4 1.0g,KH2PO4 1.0g,CaC12 0.15g,MgSO4 0.25g.The optimal culturing condition was:initial pH value 5.5,volume proportion 60mL/250mL,culture temperature 29℃,culture time 8 days.The highest inhibition rate against Pyricularia oryzae could reach to 75.5%. |
