摘　　要：采用包衣处理的方法研究了11%精甲·咯·嘧菌悬浮种衣剂(FS)不同剂量对种子出苗率的影响及对水稻恶苗病、稻瘟病的防治效果。结果表明,11%精甲·咯·嘧菌FS按照药种质量比(m/m)1∶300、1∶400、1∶500处理后种子出苗率分别为82.67%、86.67%和77.33%,均高于空白对照组75.67%;对水稻恶苗病有很好防效,分别达90.70%、89.53%和88.37%;对水稻稻瘟病的防治效果在10%以下,防效较差。因此,防治稻瘟病不建议用此药,防治水稻恶苗病的药种比(m/m)采用1∶400更为经济有效。Efficacy of Metalaxyl-M·fludioxonil·azoxystrobin 11%(FS)on the emergence rate of seeds and the control efficacys of FS on bakanae and blast of rice were studied by the method of coating treatment.The results showed that the seed emergence rate of 11%FS was 82.67%,86.67%and 77.33%respectively,which was higher than that of the blank control group(75.67%).The control efficacy on bakanae disease was 90.70%,89.53%and 88.37%,respectively,and the control efficacy on rice blast was less than 10%.Therefore,it is not recommended to use this fungicide to control rice blast.The ratio of fungicide to bakanae disease of rice(m/m)was 1:400,which was more economic and effective.
