| 摘 要： | 选用7种杀菌剂,研究了拌种和喷雾2种方法对玉米褐斑病的防治效果。结果表明:利用7种供试药剂进行种子包衣,对玉米出苗率和生长发育影响不大,但对褐斑病防治效果较佳;而在玉米5~6叶期2次喷雾,对玉米褐斑病具有较好的防治效果,并且防治效果可持续到乳熟后期。世高和粉锈宁药剂对褐斑病的防治效果较好,平均防效分别达96.79%和93.1%。 |

| Abstract: | The control effects of seven fungicides on maize brown spot were compared by seed dressing and spraying.The results showed that seed dressing had no influence on emergence rate and growth and development of maize,while the control effect on brown spot was bad.Spraying fungicides at 5-6 leaf stage two times could control effectively brown spot,and the effects could be continued to the late of milk stage.The control effects of difenoconazole and triadimefon were better,which were 96.79% and 93.1%. |
