摘　　要：分别在冬前与早春开展麦田禾本科杂草防除试验及安全性观察,结果显示,高剂量冬前使用5%唑啉草酯EC及早春使用3.6%二磺·甲碘隆WG均对小麦略有影响;冬前禾本科杂草防除选择6.9%精唑禾草灵EW、5%唑啉草酯EC、7.5%啶磺草胺WG等单剂与50%苯磺异丙WP复配使用,可取得较好的防除效果。在早春,几种除草剂与50%苯磺异丙WP复配使用对麦田禾本科杂草防除的优势不明显,而5%唑啉草酯EC和6.9%精唑禾草灵EW单剂对菵草均具有较好的防除效果,可推广用于早春菵草田块的杂草防除。Efficacy and wheat selectivity tests for several herbicides on gramineous weeds were conducted before winter and in early spring,respectively.Both pinoxaden 5%EC used before winter and mesosulfuron-methyl·iodosulfuron-methyl soudium 3.6%WG used in early spring were slightly toxic to wheat.Fenoxaprop-P-ethyl 6.9%EW and pinoxaden 5%EC compounded with tribenuron·isoproturon 50%WP,respectively,were more effective than using only one herbicide before winter,but not in early spring.Pinoxaden5%EC and fenoxaprop-P-ethyl 6.9%EW provided better control of Beckmannia syzigachne(Steud.)Fernald than other herbicides in early spring.
