摘　　要：文章为验证30%嘧菌酯·戊唑醇悬浮液对马铃薯早疫病的防治效果,开展了大田生产试验研究:设计了600mL/hm^2、450mL/hm^2、300mL/hm^2三个浓度进行验证。结果表明:30%嘧菌酯·戊唑醇悬浮液防治马铃薯早疫病有很好的效果,在早疫病发病初期开始喷施600mL/hm^2,连续喷施3次,防效达85.8%。可作为防治马铃薯早疫病药剂使用。This study aims to clarify the control effects of 30%azoxystrobin·tebuconazole suspension against potato early blight,and provide the basis for security application in yield.3 different concentration treatments of 600 m L/hm^2,450 m L/hm^2 and 300 m L/hm^2 were used to study control effect on potato early blight.The result showed that 30%azoxystrobin·tebuconazole suspension had better control effect.The control effect of leaf surface spraying 30%azoxystrobin·tebuconazole suspension 600 ml/hm^2 every 7-10 days and three times continuously at the early occurrence of early blight was 85.8%.30%azoxystrobin·tebuconazole suspension could be used for prevention and control potato early blight.
