摘　　要：[目的]通过田间药效试验明确48%双氟磺草胺·氯氟吡氧乙酸·2甲4氯异辛酯悬浮剂在冬小麦田的应用前景。[方法]于2013、2014年连续2年采用田间小区试验的方法,研究了其对小麦田主要阔叶杂草的防除效果及对小麦的安全性。[结果]48%双氟磺草胺·氯氟吡氧乙酸·2甲4氯异辛酯悬浮剂的田间推荐用量为360.00-450.00 ga.i./hm2,药后40 d鲜质量防效可达90%以上。[结论]48%双氟磺草胺·氯氟吡氧乙酸·2甲4氯异辛酯悬浮剂对小麦田主要阔叶杂草猪殃殃、荠菜、播娘蒿均有很好的防除效果,且对小麦安全,增产作用显著。[Aims] Based on the field trials, this paper aims to clarify the application prospect of florasulam, starane- MCPA-isooctyl （FSM） 48% SC in winter wheat fields. [Methods] A field trial was carried out to study and evaluate the safety on the control ofbroadleafweeds in winter wheat fields in 2013 and 2014. [Results] The recommended dose of FSM 48% SC was 360.00-450.00 g a.i./ha, the inhibition rate of fresh weight was more than 90% on the 40th day after application. [Conclusions] The control effects of FSM 48% SC on Descurainia sophia, Copsella bursa-pastoris and Galium aparine were excellent, and the yield increased.
