为探讨75％苯磺隆水分散粒剂对春小麦田一年生阔叶杂草的防除效果和对春小麦的安全性，该研究进行了田间小区试验。结果表明：75％苯磺隆水分散粒剂在春小麦使用的适宜的施药时期为小麦苗后4～5叶期，一年生阔叶杂草株高不超过5 cm ；推荐有效成分用量为18．0～22．5 g·hm-2，在推荐剂量范围内对供试的春小麦安全。施药后30 d ，对一年生阔叶杂草的合计株防效为95．9％～99．2％，鲜重防效为97．6％～99．7％。
為探討75％苯磺隆水分散粒劑對春小麥田一年生闊葉雜草的防除效果和對春小麥的安全性，該研究進行瞭田間小區試驗。結果錶明：75％苯磺隆水分散粒劑在春小麥使用的適宜的施藥時期為小麥苗後4～5葉期，一年生闊葉雜草株高不超過5 cm ；推薦有效成分用量為18．0～22．5 g·hm-2，在推薦劑量範圍內對供試的春小麥安全。施藥後30 d ，對一年生闊葉雜草的閤計株防效為95．9％～99．2％，鮮重防效為97．6％～99．7％。
