摘　　要：利用生长速率法测定5种杀菌剂对黄瓜靶斑病菌[Corynespora cassiicola(Berk curt)Wei]的室内药效。结果表明:35%苯甲·咪鲜胺、25%咪鲜胺、70%甲基硫菌灵对黄瓜靶斑病菌的抑制作用较为显著,EC50分别为:0.35μg/mL,0.39μg/mL,0.37μg/mL,而10%苯醚甲环唑和嘧菌酯对黄瓜靶斑病菌的EC50明显高于前3种处理,其中10%苯醚甲环唑的EC50最高为4.55μg/mL,抑菌作用最差。By means of the mycelium growth rate methods, effectiveness of five fungicides on cucumber Corynespora cassiicola （Berk curt） Wei was evaluated in door. The results showed that when using 35% difenoconazole-prochloraz, 25% prochloraz and 70% thiophanate-methyl, the suppressive effects on cucumber Corynespora cassiicola （Berk curt） Wei were significant, the value of EC50 were 0.35 μg/ml, 0.39μg/ml and 0.37 μg/ml. But the value of EC50 of 10% difenoconazole and azoxystrobin were obviously higher than that of 35% difenoconazole -prochloraz, 25% prochloraz and 70%Thiophanate-methyl. The highest value of EC50（4.55 μg/ml） was 10% difenoconazole, which had the worst suppressive effect.
