| 摘 要： | 本文报道了12种杀菌剂防治水稻纹枯病的田间试验研究。结果表明:噻呋酰胺24%悬浮剂339g/hm2、嘧菌酯25%悬浮剂500g/hm2、丙环唑25%乳油750g/hm2在2次药后15d对水稻纹枯病的防治效果分别为91.5%、88.1%、86.6%,显著高于其他处理;肟菌·戊唑醇75%水分散粒剂防效为77.0%,稍次于丙环唑25%乳油;其他8种杀菌剂的防效在54.1%~68.7%之间,防效不太理想;井冈霉素20%可湿性粉剂的防效仅为56.6%,故笔者认为在水稻纹枯病大发生年份,尽量选用其他高效的杀菌剂进行预防和防治。

| Abstract: | This paper studied the efficacy of twelve fungicides against rice sheath blight.The results showed that： on 15 days after treatment, the control efficacy of thifluzamide 24% SC 339g/hm^2、 azoxystrobin 25% SC 500g/hm2、 propiconazole 25% EC 750g/hm^2were 91.5%、 88.1%、 86.6%, significantly higher than other treatments; The trifloxystrobin.tebuconazole 75% WDG were 77% lower than propiconazole 25% EC; the control effect of other 8 fungicides were not ideal, which between 54.1% and 68.7%; The validamycin 20% WP was 56.6%, so we could apply other effective fungicides to prevent and control when rice sheath blight outbreak. |
