摘要 采用菌落直径法,分别测定了7大类8种常用杀菌剂对黄瓜枯萎病菌的室内毒力。结果表明,8种供试杀菌剂对黄瓜枯萎病菌的作用效果均较好,其中三唑类丙环唑的毒力最高,EC50值为0.023mg/L。咪鲜胺、苯醚甲环唑、咯菌腈、百菌清和嘧菌酯的毒力也较高,EC50均低于1.0mg/L;多菌灵和异菌脲对黄瓜枯萎病的毒力分别为1.105和1.181mg/L,仍有较好的作用效果。 The toxicities of 8 fungicides belonging to 7 categories to cucumber Fusarium wilt were measured using colony diameter method. The results showed that all 8 fungicides presented preferable control efficiency, and of which propiconazole presented the highest toxicity, with EC50 value 0.023mg/L. Prochloraz, difenoconazole, fludioxonil, chlorothalonil, and azoxystrobin had the EC50 values lower than 1.0mg/L. The EC50 values of carbendazim and iprodione were1.105 and 1.181mg/L respectively, and had a good effect for cucumber fusarium wilt control.
