摘要
研究了在不同时期喷施不同剂量的异丙.苯磺可湿性粉剂(麦哥,简称为异丙隆)对麦田杂草的防治效果。结果表明:在杂草2叶1心～3叶1心时期,应用异丙隆防治杂草效果最好,可选用剂量为1 791 g/hm2的异丙隆防治硬草;在杂草4叶期～5叶期,可选用2 687 g/hm2的剂量进行防治;在春季小麦返青期,使用3 582 g/hm2的剂量,防效较差。
The control effects of different period and doses of isoproturon on weeds in wheat field were stuied.The results showed that the control effects of 1 791 g/hm2 isoproturon was the best at 2-3 leaves stage,the optimal dose of isoproturon was 2 687 g/hm2 at 4-5 leaves stage,and the control effect was bad at retuning green stage.
