摘要
为筛选防治水稻纹枯病的理想长效药剂,本站选择了10种药剂进行了田间药效试验,各期调查,均以每667m2用嘧菌酯·噻呋酰胺20%水分散粒剂70g、嘧菌酯·戊唑醇75%水分散粒剂10g、噻呋酰胺·已唑醇27.8%悬浮剂20m L、噻呋酰胺24%悬浮剂20m L、肟菌·戊唑醇75%水分散粒剂15g、嘧菌脂25%悬浮剂30m L等6种药剂处理对水稻纹枯病具有很好的防控效果,用药1次,可有效控制20d以上,对水稻生长安全,是防治水稻纹枯病的理想长效药剂。
10 fungicides were chosen to test the control effect against Rice Sheath Blight. The result showed that the following six treatments, Azoxystrobin-Thifluzamide 20% WG 70 g, Azoxystrobin-Tebuconazole 75% WG 10 g, Thifluzamide-Hexaconazole 27.8% SC 20 m L, Thifluzamide24% SC 20 m L, Oxime-Tebuconazole 75% WG 15 g and Azoxystrobin 25% SC 30 m L per 667m2,could control the disease effectively, and were safe for rice growth.
