为验证20%双氟·氟氯酯水分散粒剂(锐超麦)对冬小麦田阔叶杂草的防除效果以及对小麦的安全性,采用常规茎叶喷雾法测定了20%双氟·氟氯酯水分散粒剂对小麦田阔叶杂草的田间药效,结果表明,用20%双氟·氟氯酯水分散粒剂75.0 g/hm~2+专用助剂0.1%(v/v)、97.5 g/hm~2+专用助剂0.1%(v/v)对总体杂草的株防效在78%以上,鲜重防效在93%以上,同时对小麦安全,小麦增产率达14%以上。
In order to verify the control effect of 20% difluoro-chlorofluorocarbon ester water dispersible granules (Rui Chao Mai) on broad-leaved weeds in winter wheat field and its safety to wheat, 20% difluoro-fluoro The results showed that with 20% difluoro-chlorofluorochloridic water dispersible granules 75.0 g / hm ~ 2 + 0.1% (v / v) ), 97.5 g / hm ~ 2 + 0.1% (v / v) of special auxiliaries were more than 78% for the control effect on weeds and over 93% for fresh weight. At the same time, More than 14%.
