摘　　要：为研究不同杀菌剂对玉米叶斑病的防治效果,以清水为对照,设置75%肟菌·戊唑醇水分散粒剂、38%吡唑·氟环唑悬浮剂、325 g/L苯甲·嘧菌酯悬浮剂、17%唑醚·氟环唑悬浮剂、22.5%啶氧菌酯悬浮剂和41%甲硫·戊唑醇悬浮剂6个处理,探究不同处理对玉米小斑病、大斑病和弯孢菌叶斑病的防治效果,结果表明,6个处理均对玉米叶斑病有较好防效,综合防效均达60%以上,其中38%吡唑·氟环唑悬浮剂对玉米小斑病的防效达82.35%,17%唑醚·氟环唑悬浮剂对玉米大斑病和弯孢菌叶斑病防效分别达75.76%、88.43%。综合考虑认为,17%唑醚·氟环唑悬浮剂对于玉米病害防治效果最好,可用于实际生产。To study the control effects of different fungicides on maize leaf spot disease,water was used as a control,and six treatments were set up,including 75%oxime bacteria tebuconazole water dispersible granules,38%pyrazole fluconazole suspension,325 g/L benomyl fenpyrazine suspension,17%imidazole ether fluconazole suspension,22.5%imidacloprid ester suspension,and 41%methylthio tebuconazole suspension,to study the control effects on maize small spot disease,large spot disease,and curvularia leaf spot disease.The results showed that:all six pesticides have good control effects on maize leaf spot disease,with a comprehensive control effect of over 60%.38%pyrazole fluconazole SC has a control effect on maize small spot disease of 82.35%,and 17%imidazole fluconazole SC has a control effect on maize big spot disease and curvularia leaf spot disease of 75.76%and 88.43%,respectively.Through comparative analysis of experimental data,it can be concluded that 17%imidazole fluconazole SC has the best control effect on maize diseases and can be used for actual production.
