摘　　要：8种杀菌剂对雪莲果褐斑病的室内毒力测定结果表明:供试药剂毒力由高到低依次为325g/L苯甲·嘧菌酯悬浮剂、10%苯醚甲环锉水分散粒剂、206.7g/L噁酮·氟硅唑乳油、125g/L氟环唑悬浮剂、250g/L吡唑嘧菌酯乳油、60%唑醚·代森联水分散粒剂、50%醚菌酯水分散粒剂和46%氢氧化铜水分散粒剂。以325g/L苯甲·嘧菌酯悬浮剂的抑制作用最好,其EC50为0.28mg/L。Fungal toxicity testing indicated that the inhibition of eight kinds of fungicides against brown spot of yacon were very different and their toxicity from high to low were followed by 325g/L benzoic,azoxystrobin,10%difenoconazole file,206.7g/Ldioxanone flusilazole,125g/L epoxiconazole,250g/L pyrazole azoxystrobin,60% ether metiram,50% water kresoxim and 46% cupric hydroxide respectively,and 325g/L Benzene armour was the best inhibition.Its EC50 was only 0.28mg/L.
