摘　　要：[目的]为明确37%苄嘧磺隆·唑草酮·炔草酯WP对冬小麦田一年生杂草的防治效果和对小麦的安全性。[方法]小麦返青后、拔节前,采用茎叶喷雾施药,定期调查杂草防效和对小麦影响。[结果]37%苄嘧磺隆·唑草酮·炔草酯WP的田间推荐用量为77.7～99.9 g a.i./hm^2。施药28 d后对杂草株数总体防效达90.30%～99.02%,鲜质量总体防效达93.06%～99.42%。[结论]37%苄嘧磺隆·唑草酮·炔草酯WP能有效防除冬小麦田一年生杂草并对小麦具有较好的安全性。[Aims] The study aims to clarify the control efficacy and security of bensulfuron, carfentrazone and clodinafop 37% WP against weeds in winter wheat field. [Methods] Leaf spray was carried out after the wheat turning green and before jointing, and then the control efficacy and impact on wheat were investigated regularly. [Results] The recommended dose of bensulfuron, carfentrazone and clodinafop 37% WP was 77.7-99.9 g a.i./ha. The integrated control efficacy of weeds number and fresh weight were 90.30-99.02% and 93.06-99.42% in 28 days after spraying.[Conclusions] Bensulfuron, carfentrazone and clodinafop 37% WP showed a good control efficacy to weeds in winter wheat field and is safe to the growth of wheat.
