摘　　要：试验采用菌丝生长抑制法测定了25%凯润EC、25%阿米西达SC、10%世高WG、70%甲基托布津WP、80%大生M-45 WP、50%速克灵WP 6种杀菌剂对枣(Ziziphus jujuba Mill)黑斑病菌(Alternaria alternate)的室内活性。结果表明,6种杀菌剂对枣黑斑病菌均有抑制效果,但抑制效果存在显著差异。其中25%凯润EC、25%阿米西达SC、10%世高WG、70%甲基托布津WP对枣黑斑病菌都有较好的抑制作用,抑制中浓度(EC50)分别为0.032 5、13.403 6、39.872 2、54.254 0μg/m L;80%大生M-45 WP、50%速克灵WP对枣黑斑病菌的抑制效果较差,EC50分别为325.890 7μg/m L和629.806 3μg/m L。The mycelial growth rate methed was used to test the indoor toxicity of six fungicides 25% pyrazole ether ester EC,25% Amistar SC,10% difenoconazole WG,70% mildothane WP,80% mancozeb WP, 50% procymidone WP aginst jujube black spot（Alternaria alternate）.The results showed that 6 fungicides had inhibition effects to jujube black spot（Alternaria alternate）,which had significant different inhibitory effect. 25% pyrazole ether ester EC,25% Amistar SC,10% difenoconazole WG and 70% mildothane WpHad good inhibition,median inhibition concentration（EC50） were 0.032 5,13.403 6,39.8722,54.254 0 μg / mL respectively; While 80% mancozeb WP,50% procymidone WpHad poorer inhibition effect to jujube black spot,EC50 were 325.890 7 μg / mL and 629.806 3 μg / mL respectively.
