50%吡氟酰草胺可湿性粉剂(骄马)及其他常用除草剂对稻茬麦田杂草的防效

为了探索50%吡氟酰草胺可湿性粉剂(骄马)对稻茬麦田杂草的防效,我们将其与其他几种麦田常用除草剂处理分别进行了田间试验,得出以下结论:骄马15g/667m2、20g/667m2、30g/667m2处理对阔叶杂草猪殃殃、牛繁缕防效较佳,但对播娘蒿以及硬草的防效较差且三种剂量对杂草的防效差异并不显著,因此推荐骄马15g/667m2用来防除稻茬麦田猪殃殃、牛繁缕等阔叶杂草。

In order to explore the control effect of 50%diflufenican,wettable powder,on weeds in wheat field after rice stubble,we carried out field experiments with several other common herbicides in wheat field.The following conclusions were drawn:the treatment of 15g/667m2,20g/667m2,30g/667m2 has better control effect on broad-leaved weeds,such as calamity of pigs and cattle.However,the control effect on Artemisia annua and hard grass is poor,and there is no significant difference in the control effect of the three doses on weeds,so 15g/667m2 is recommended to control broad-leaved weeds in rice stubble wheat field,such as Galium spurium L.,Myosoton aquaticum(L.)Moench,and so on.
