摘　　要： 为了解12%井冈霉素·戊唑醇悬浮剂对水稻稻瘟病(叶瘟和穗颈瘟)的防治效果、使用技术及其对水稻的安全性,每667 m2施用85、100、115 mL等3个不同浓度(制剂量)处理进行水稻稻瘟病防治效果比较试验,两年的试验结果表明:12%井冈霉素.戊唑醇悬浮剂对水稻生长安全,有较好的增产效果,防治水稻稻瘟病效果优良,其中每667 m2施用115 mL药剂处理对水稻叶瘟的防治效果分别为77.90%和75.84%,对水稻穗颈瘟的防治效果分别为77.27%和76.40%,值得在生产上试验示范和推广应用。 In order to evaluate the control effect of 12% Validamycin ＆ Tebuconazole SC against the rice blast （leaf blast and panicle blast）, its application technology and safety to rice, three different treatments, 85 mL/667m^, 100 mL/667m^ and 115 mL/667m^ were used for rice blast control effect test. The results showed that 12% Validamycin ＆ Tebuconazole SC had good effects on rice growth, productivity and controlling the rice blast in both 2010 and 2011. In these two years, the control effect of 115 mL/667m^ were respectively at 77.90% and 75.84% for the leaf blast, 77.27% and 76.40% for the panicle blast. It is worth to promote the application in production.
