摘　　要：[目的]探索新型、高效除草剂的有效、安全使用技术。[方法]进行了多种除草剂对沿江圩区稻田杂草防除的药效试验。[结果]32％苯噻酰苄乙WP是苯噻酰草胺、苄磺隆、乙草胺的复配剂，比乙草胺安全，比53％苯噻酰苄价格低，具有杀草谱广、作用时间长、施用方便、对水稻安全的特点。[结论]在水稻移栽（活棵）后，用32％苯噻酰苄乙WP750～900g/hm^2拌毒土或尿素撒施，对稻田主要杂草稗草、千金子、多花水苋、碎米莎草的防除效果可稳定在85％以上，对水稻安全。[Objective] The study aimed to explore the effective and safe using techniques for new high efficient herbicides. [Method] The effect experiment of many kinds of herbicides on controlling weed in rice field along the Yangtze River region was conducted. [ Result ] 32 % mefenacet· Bensulfuroumthyl acetochlor WP was the complex agent of mefenacet, bensulfuron-methyl and acetochlor. It was safer than acetochlor, cheaper than 53% mefenacef bensulfuron methyl and was a broad spectrum herbicide with long effect time, convenient application and safe to rice. [ Conclusion] After the rice transplanting, the control effects of broadcasting 32% mefenacet·Bensulfurou-mthyl acetochlor WP 750 - 900 g/hm^2 mixed with toxic soil or urea on the main weeds of Barnyard grass, Leptochloa chinensis, Ammamiamultiflora and Rice galingale were steady over 85 %, with safety to rice
