摘　　要：为了验证和评价3%甲酰氨基嘧磺隆可分散油悬浮剂(OD)对夏玉米田杂草的防除效果及对作物的安全性,采用田间小区试验的方法,调查了杂草的株防效和鲜质量防效,测定了当茬玉米产量。结果表明,使用3%甲酰氨基嘧磺隆可分散油悬浮剂有效成分用量为40.05～99.90 g/hm^2防除夏玉米杂草,药后35 d杂草株防效和鲜质量防效均达到97%以上,对作物安全且有一定的增产效果。从经济高效角度出发,推荐3%甲酰氨基嘧磺隆可分散油悬浮剂有效成分使用量为40.05～49.95 g/hm^2。To validate and evaluate the weed control effect and crop safety of 3% Foramsulfuron OD on weeds in summer corn field,the plant control effect and fresh quality control effect of weeds were investigated by field plot experiment, and the yield of current corn was determined. The results showed that the effective components of 3% Foramsulfuron OD were 40.05-99.90 g/hm^2 to control summer corn weeds, and the control effect of weed plant and fresh quality were above 97% after 35 days of treatment, which was safe to crops and had a certain yield-increasing effect. From the perspective of economic and efficiency, the recommended effective constituent dose of 3% Foramsulfuron OD was 40.05-49.95 g/hm^2.
