摘　　要：分析10%乙羧氟草醚EC对大豆田阔叶杂草的防除效果和最佳使用剂量,对其进行了田间药效试验。结果表明,10%乙羧氟草醚EC 300~1 200 m L/hm2处理,药后40 d对大豆田阔叶杂草的株防效达91.49%~99.87%,鲜重防效达95.65%~99.94%,可较好地控制大豆田野苋菜、马齿苋的为害,在杂草3~5叶期使用,用量以600~900 m L/hm2为宜。A field experiment was conducted to determine the efficacy of fluoroglycofen-ethyl 10%EC against broadleaf weeds in the soybean field.The results showed that the control efficacy was 91.49%~99.87%at 40 days after post-emergence treatment with fluoroglycofen-ethyl 10%EC at the application rate of 300~1 200 mL/hm2 in the soybean field,and 95.65%~99.94%(based on weed plant fresh weight)at 40 days after treatment.Fluoroglycofen-ethyl 10%EC had relatively good effect to broadleaf weeds in soybean fields and when it was applied during 3~5 leaf stage,the chemical worked well in controlling the weeds of Amaranthus spinosus L.and Portulaca oleracea L.,the suitable dosage was 600~900 mL/hm2.
