摘　　要：为筛选适宜的杀菌剂防控德国鸢尾茎腐病,测试亮盾、噁霉灵、瑞至等10种杀菌剂对德国鸢尾茎腐病菌木贼镰刀菌和尖孢镰刀菌的防控效果。结果表明,10种药剂对德国鸢尾茎基腐病病原菌菌丝的生长均有不同程度的抑制作用。其中,抑制效果最好的是解淀粉芽孢杆菌;较好的4种药剂分别为精甲·咯菌腈、噁霉灵、唑醚·甲菌灵、双炔酰菌胺·百菌清,它们对木贼镰刀菌的EC_(50)分别为1.809、61.210、55.570、17.408mg/L,对尖孢镰刀菌的EC_(50)分别为141.9、13.572、39.186、71.251mg/L。The aim of this study was to screen suitable fungicides for control of Iris germanica stem rot.The control effect of 10 fungicides,such as Liangdun,Oxaline and Ruizi,on pathogens of iris stem rot,Fusarium equiseti and F.oxysporum,were tested.The laboratory test showed that 10 kinds of fungicides had different degrees of inhibition on the growth of the mycelium of the pathogen of I.germanica stem rot.Bacillus amylolyticus had the best inhibition effect.The four kinds of fungicides had good inhibitory effect,which were fludioxonil-metalaxyl-M,hymexazol,pyraclostrobin-thiophanate-methyl,mandipropamid-chlorothalonil,and their EC_(50)against F.equisepis were 1.809,61.210,55.570,17.408 mg/L respectively.The EC_(50)against F.oxysporum were 141.9,13.572,39.186,71.251 mg/L respectively.
