摘　　要：[目的]筛选防治水稻烂秧病的有效药剂。[方法]采用田间小区试验的方法,评价了7种药剂对水稻烂秧病的防治效果,同时测定了其对水稻出苗率及秧苗素质的影响。[结果]10%噻虫嗪·咯菌腈·精甲霜灵种子处理悬浮剂、5%精甲霜灵·咯菌腈·嘧菌酯种子处理悬浮剂、10%精甲霜灵·嘧菌酯·戊唑醇种子处理悬浮剂对水稻烂秧病的防治效果可达80%以上。供试药剂处理对稻种出芽率影响较小,差异不显著。各处理剂量秧苗素质与空白对照相比差异不显著。[结论]7种药剂对水稻烂秧病均具有一定的防治效果,可以为防治水稻烂秧病的后续研究提供参考。[Objective] The aim was to screen out fungicides for control of the rice seedling rot disease.[Method] The field trial was conducted to test the control effects of 7 fungicides against the rice seedling rot disease. [Result] The results showed that all the 7 fungicides had the control effects against the rice seedling rot disease. The clothianidin·metalaxyl-M·fludioxonil 10% ZX,metalaxyl-M·fludioxonil·azoxystrobin 5% ZX and metalaxyl-M·azoxystrobin·tebuconazole 10% ZX showed that the control effect were over 80%. The test treatment had little effect on the germination rate of rice seeds,and the difference was not significant. There was no significant difference in seedling quality between the treatments and the blank control. [Conclusion]All the 7 fungicides have certain control effects on rice seedling rot,which could provide reference for the follow-up research on the control of rice seedling rot.
