为明确75%肟菌酯·戊唑醇水分散粒剂对玉米大斑病控制效果,进行了75%肟菌酯·戊唑醇水分散粒剂与当地常规药剂的大区对比试验。结果表明,在玉米大斑病发生初期,用75%肟菌酯·戊唑醇水分散粒剂225~300 g/hm2,间隔10 d,连喷2次,能有效控制玉米大斑病,持效性较好,增产显著,试验期间未发现对作物有药害现象,可在生产中大面积推广应用。
In order to clarify the control effect of 75% trifloxystril and tebuconazole water dispersible granule on corn leaf spot disease, a large area comparative test was conducted between 75% trifloxystrobin and tebuconazole water dispersible granule and the local routine medicament. The results showed that in the early stage of maize leaf spot, 75% trifloxystrobin and tebuconazole water dispersible granules 225 ~ 300 g / hm2, spraying for 10 days, could effectively control leaf spot of maize blight Effectiveness is good, yield significant, during the experiment found no crop injury, can be widely applied in production.
