【摘要】 为有效防治水稻纹枯病,对市售药剂进行了田间药剂筛选试验。结果表明:在水稻分蘖期与孕穗期2次施药情况下,240 g/L噻呋酰胺SC防效最好,在95%左右。325 g/L苯甲·嘧菌酯SC、75%肟菌·戊唑醇WG能有效防治水稻纹枯病,药效在80%以上。18.7%丙环·嘧菌酯SC需提高剂量再进行试验。300 g/L苯甲·丙环唑EC防效较差。所有药剂处理对水稻均安全。更多还原

【Abstract】 In order to control rice sheath blight effectively,fungicides screening test was carried out.The results showed that thifluzamide 240 g/L SC had the best control effect.Difenoconazole + azoxystrobin 325 g/L SC,trifloxystrobin +tebuconazole 75% WG could control rice sheath blight,with the efficiencies over 80%.Difenoconazole + propiconazole300 g/L EC provided relatively poor control effect on rice sheath blight.更多还原
