摘　　要：[目的]为明确39%辛酰溴苯腈·烟嘧磺隆·莠去津油悬浮剂对玉米田杂草的防除效果及对玉米发育的影响和安全性。[方法]采用茎叶喷雾,定期调查的方法进行田间药效试验。[结果]39%辛酰溴苯腈·烟嘧磺隆·莠去津油悬浮剂的推荐用量为526.5～585 g a.i./hm^2,药后35 d对杂草的总体防效可达到99.46%。[结论]39%辛酰溴苯腈·烟嘧磺隆·莠去津油悬浮剂能够有效防除玉米田杂草,并对玉米有较好的安全性。[Aims] The study is to confirm the control effect and security of 39% OF of bromoxynil octanoate,nicosulfuron, and atrazine against weeds in summer corn field. [Methods] Field trais were carried out by using methods of stem-leaves spraying and regular survey. [Results] The result showed that the herbicide could effectively control the weeds in corn field. The recommended dosage is 526.5-585 g a.i./ha, and the integrated control effect reached 99.46% on weeds after 35 d. [Conclusions] Bromoxynil octanoate·nicosulfuron·atrazine 39% OF shows good control to weeds in summer corn field and is safe on corn growth.
