研究氟磺胺草醚·烯草酮21%油悬浮剂对绿豆田杂草的防除效果。用药后30d,对禾本科杂草的株防除效果为80.35%～99.62%,阔叶杂草的株防除效果为80.57%～99.71%,鲜重防除效果为80.52%～99.66%,对绿豆产量增产幅度为9.8%～20.4%。在推荐剂量下,对绿豆生长安全。经试验表明,该油悬浮剂能有效防除绿豆田禾本科杂草和阔叶杂草。

To study the control effect of fomesafen and clethrene 21% oil suspension on weeds in mung bean field. The control effect on the weeds was 80.35% ~ 99.62% 30 d after treatment, the control effect of broadleaf weeds was 80.57% ~ 99.71%, and the control effect of fresh weight was 80.52% ~ 99.66% The magnitude is 9.8% ~ 20.4%. At the recommended dose, the growth of mung beans is safe. The experiments show that the oil suspension agent can effectively control mung bean weeds and broad-leaved weeds.
