摘　　要：为明确75%磺酰磺隆WG对春小麦田杂草的防除效果及对当季春小麦和后茬作物的安全性影响,采用茎叶喷雾处理进行了田间药效试验。结果表明：施药后45 d,75%磺酰磺隆WG 10～40 g/hm^2对北方春小麦田稗草、狗尾草、藜和卷茎蓼株防效和鲜重防效均在84.8%以上,且对春小麦安全。75%磺酰磺隆WG对当季后茬敏感作物白菜、油菜、生菜的根长、株鲜重有不同程度的抑制作用。75%磺酰磺隆WG在春小麦田喷雾使用可以有效防除禾本科杂草和阔叶杂草,但当季后茬不能种植敏感作物白菜、油菜、生菜。In order to determine the control effect of sulfosulfuron 75%WG on weeds in spring wheat field, the safety to spring wheat and following crops, field efficacy trials were carried out by foliar spraying. The results showed that the control effects of sulfosulfuron 75%WG on Echinochloa crusgalli （L.） Beauv., Setaria viridis L., Chenopodium album L. and Polygonum convolvlus L. were more than 84.8%, and sulfosulfuron was safe to spring wheat on the 45th days after spraying. Sulfosulfuron 75%WG had inhibition roles on the root length and fresh weight of sensitive crops. Sulfosulfuron 75%WG had good control effects on gramineous weeds and broadleaf weeds in spring wheat field in north China, but the sensitive crops should not be planted in the same growing season.
