摘　　要：[Objective] This study aimed to investigate the effectiveness of different rates of 10% cyhalofop-butyl EW for control of Poaceae weeds in transplanted rice in China. [Method] The experimental and eco-friendly herbicide, 10% cyhalofop-butyl EW, was applied in field trials in 2013 to investigate its efficacy in five representa-tive rice producing areas, one in each of the provinces Anhui, Hunan, Zhejiang, Jiangsu and Liaoning. [Result] The results showed that 10% cyhalofop-butyl EW could effectively control Poaceae weeds in transplanted rice without negative effects on the rice crop. The optimal application rate of 10% cyhalofop-butyl EW was found to be 750-1 500 ml/hm2. [Conclusion] The study confirmed that 10% cyhalofop-butyl EW has clear potential for wide-spread adoption in rice production systems.[目的]探讨不同剂量10%氰氟草酯水乳剂对我国水稻移栽田主产区田间杂草的防除效果。[方法]以新型环境友好型的10%氰氟草酯水乳剂为供试药剂，在我国具有代表性的安徽、湖南、浙江、江苏、辽宁5个水稻主产区进行水稻田除草药效试验。[结果]10%氰氟草酯水乳剂对水稻田禾本科杂草具有良好的防除效果且对水稻生长安全，推荐使用制剂用药量750~1500 ml/hm2。[结论]10%氰氟草酯水乳剂具有较好的推广应用前景。
