摘要

引进稻艳等几种药剂进行稻瘟病防效试验，田间试验结果表明，75%稻艳可湿性粉25g/667m2对水稻稻瘟病具有较好的防治效果，药后7d防效达78.1%，药后14d防效达86.1%，明显优于其他对比的几种药剂，可以较好地防治稻瘟病，生产中可以建议使用。%The effect of several introduced medicaments such as Daoyan on rice blast control was carried out. Field test results showed that spraying 25 g/667m2 of 75% Daoyan wettable power had a better control effect on rice blast. Its control effect reached 78.1% and 86.1% at 7 d and 14 d after spraying respectively, which exhibited significantly better than the other pesticides.
