摘　　要：[目的]研究10%精甲霜灵·戊唑醇·嘧菌酯悬浮种衣剂对水稻恶苗病的防效。[方法]在水稻浸种前进行包衣处理,比较了4种药剂对水稻恶苗病的苗期及田间防效,以期筛选出对水稻恶苗病防效好的药剂及其适宜用量。[结果]10%精甲霜灵·戊唑醇·嘧菌酯种衣剂对水稻恶苗病有较好防效,3 ml/kg种子田间防效最高,为91.65%,与对照药剂差异达到极显著水平。[结论]10%精甲霜灵·戊唑醇·嘧菌酯悬浮种衣剂可用于水稻恶苗病的防治,推荐使用制剂量为2~3 ml/kg种子。[Aims]This paper aims to study the efficacy of talaxyl-M·tebuconazole·azoxystrobin 10%FSC on the controlling of rice bakanae disease.[Methods]The control effects of 4 chemicals on rice seedling stage and field were compared before seed soaking in order to screen out the effective chemicals and their suitable dosage.[Results]The results showed that metalaxyl-M·tebuconazole·azoxystrobin 10%FSC has best efficacy for controlling rice bakanae disease,and the highest efficacy 91.65%in 3 ml/kg,which was significantly different from the control.[Conclusion]The metalaxyl-M·fludioxonil·azoxystrobin 10%FSC was effective in control of the rice bakanae disease.The recommended concentration is 2-3 ml/kg.
