摘　　要：对250g/L氟磺胺草醚水剂防除夏大豆田阔叶杂草进行了田间药效试验。结果表明:250g/L氟磺胺草醚水剂,施药量为225～412.5g/hm2对杂草的防治效果较好,药后20d、40d株防效分别达94.3%～98.6%、87.3%～95.5%,药后40d鲜重防效达87.7%～97.0%,增产15.22%～19.02%。Efficacy of fomesafen 250 g/L SL against weeds in the soybean field was investigated. Result showed that fomesafen 250 g/L SL had a good control efficacy against grasses at apphcation rate of 225-412.5 g/hm^2. The control efficacy based on weed plant number was 94.3%-98.6% 20 days after treatment and 87.3%-95.5% 40 days after treatment, respectively; and that the control efficacy based on weed plant fresh weight was 87.7%-97.0% 40 days after treatment.
