摘　　要：4%精甲霜灵·咯菌腈·嘧菌酯悬浮种衣剂是登记用于防治水稻苗期病害的杀菌剂新产品。采用室内与田间相结合的方法开展了该种衣剂的种子包衣对水稻出芽率、秧苗素质、防病效果以及作物安全性试验,以期为其推广应用提供技术支撑。试验结果表明4%精甲霜灵·咯菌腈·嘧菌酯悬浮种衣剂按1∶150、1∶100、1∶80的药种比包衣寒地水稻种子,对水稻苗期恶苗病、立枯病、青枯病及大田恶苗病具有较好的防控效果,包衣后的水稻种子发芽率提高、稻苗叶龄进程加快、根数增多、茎基加宽、充实度提高。说明该种衣剂可明显提高水稻苗素质,且对水稻安全。Metalaxyl-M·fludioxonil·axostrobin 4%FS is a new fungicide registered to control the rice seedling diseases.The germination rate,seedling quality,control efficacy on the seeding diseases and rice phytotoxicity were investigated after soaking rice seeds with metalaxyl-M·fludioxonil·axostrobin 4%FS based on laboratory and field experiments in order to provide the technical support for its application.Results showed that metalaxyl-M·fludioxonil·axostrobin 4%FS could effectively control rice rot,rice blight,banakae disease in the rice seedling stage and banakae disease in growing stage,especially in cold areas.Metalaxyl-M·fludioxonil·axostrobin 4%FS can imporve the seedling quality such as the quick growth of leaf age,the increasing number of roots,the widening stem base,and the fullness improved,and it had no phytotoxicity to rice seedlings at the recommended dosage.
