摘要
[目的]比较4种除草剂30 g/L甲基二磺隆油悬浮剂、3.6%二磺.甲碘隆水分散粒剂、69 g/L精唑禾草灵水乳剂和15%炔草酸可湿性粉剂防除看麦娘效果和对小麦安全性。[方法]小麦返青后、拔节前一次性喷药后于不同时期调查杂草防效和对小麦影响。[结果]4种除草剂均能不同程度抑制看麦娘生长,除15%炔草酸可湿性粉剂外,其他除草剂高用量对小麦均有不良影响。[结论]在小麦返青后可使用15%炔草酸可湿性粉剂,使用其他药剂时要注意用量。
The herbicidal efficacy and security of four herbicides,mesosulfuron-methyl 30 g/L of,mesosulfuron-methyl·iodosulfuron-methyl-sodium 3.6% WG,fenoxaprop-P-ethyl 69 g/L EC and clodinafop-propargyl 15% WP was studied.[Methods] 4 herbicides were applied at wheat recovering date and then control effect and injure to wheat were investigated at different stages.[Results] All 4 herbicides can inhibit Alopecurus aequalis at different level.Except clodinafop-propargyl 15% WP,the other three herbicides can injure wheat at higher concentration.[Conclusions] After wheat turns green,clodinafop-propargyl 15% WP can be used to prevent A.aequalis,the other three herbicides should be payed attention to their concentration in this stage.
