试验结果表明,3.2%恶·甲水剂4 000～4 800g a.i./hm2在水稻播种前进行苗床土壤处理,对水稻立枯病具有较好的防治效果,药后30d防效仍达86.06%～88.29%,明显优于常用单剂甲霜灵、恶霉灵,且对水稻出苗、生长安全。大面积推广应用时,建议3.2%恶·甲水剂使用量为4 000g a.i./hm2,对常年发病较重的田块建议使用量为4 800g a.i./hm2。 The results showed that 3.2% of the evil · A water agent 4 000 ~ 4 800 g ai / hm2 before sowing rice seedbed soil treatment, the control of rice blight has a better control effect 30 d after the drug control effect still reached 86.06% 88.29%, significantly better than the commonly used single agent metalaxyl, hymexazol, and the emergence of rice, growth and safety. For large-scale popularization and application, it is suggested that the use amount of 3.2% of the evil and water-based agent is 4 000 g a.i./hm2, and the suggested dosage for the perennial severe disease is 4 800 g a.i./hm2.
