[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./hm2。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。 [Objective] The research aimed to clarify the control effect of 37% bensulfuron-methylpyclononadione and WP against winter weeds in winter wheat field and its safety to wheat. [Method] After returning to green, wheat was sprayed with stems and leaves before spraying. The weed control effect and the impact on wheat were investigated regularly. [Result] The recommended dosage of WP was 37.7 ~ 99.9 g a.i./hm2 for 37% bensulfuron-methyl. After 28 days of application, the overall control effect on the number of weeds reached 90.30% -99.02%, and the overall control effect of fresh quality reached 93.06% -99.42%. [Conclusion] The 37% bensulfuron-methylpymenebuprofen WP could effectively control annual weeds in winter wheat field and had good safety to wheat.
