采用生长速率法测定9种杀菌剂对蘑菇疣孢霉属(Mycogone)3个类型菌株和双孢蘑菇(Agaricusbisporus)菌丝的室内毒力。结果表明:不同杀菌剂对不同类型疣孢霉菌株和双孢蘑菇菌丝生长均具有不同程度的抑制作用,Ⅰ、Ⅱ、Ⅲ类菌株的最佳杀菌剂分别为氟硅唑(EC50=0.0058μg/mL)、咪鲜胺(EC50=0.0067μg/mL)、戊菌唑(EC50=0.0287μg/mL),双孢蘑菇菌丝对咪鲜胺(EC50=2.2526μg/mL)敏感性最小,综合分析,氟硅唑、咪鲜胺均适用于疣孢霉Ⅰ、Ⅱ类菌的防治,百菌清(EC50=0.0631μg/mL)可用于Ⅲ类菌防治。
The indoor toxicity of 9 fungicides to three strains of Mycogone and Agaricus bisporus mycelia was determined by growth rate method. The results showed that different fungicides had different degrees of inhibition on the mycelial growth of different types of Mycoplasma sp. And Agaricus bisporus. The best fungicides of class I, II and III were flusilazole (EC50 = 0.0058μg (EC50 = 0.0067μg / mL) and penconazole (EC50 = 0.0287μg / mL). The mycelia of Agaricus bisporus had the least sensitivity to prochloraz (EC50 = 2.2526μg / mL) Analysis, flusilazole, prochloraz are suitable for the prevention and treatment of Mycosphaeroides class Ⅰ, Ⅱ bacteria, chlorothalonil (EC50 = 0.0631μg / mL) can be used for class Ⅲ bacteria prevention and treatment.
