摘　　要：为了筛选出适合江苏省句容地区防除小麦田阔叶杂草的除草剂品种,采用茎叶喷雾法,在田间比较了10种常用除草剂对小麦田阔叶杂草的防效。施药后18 d调查结果表明,2%吡草醚EC对黏毛卷耳、10%唑草酮WP和4%啶磺草胺OD对猪殃殃防效均在90%以上;供试10种除草剂对大野豌豆的防效均在70%以下;而对总杂草的防效仅2%吡草醚EC为72.67%,其他品种的防效均在60%以下。施药后34 d调查结果表明4%啶磺草胺OD、56%2甲4氯钠SP、80%唑嘧磺草胺WG、20%氯氟吡氧乙酸EC和2%吡草醚EC对黏毛卷耳株防效均在90%以上;50 g/L双氟磺草胺SC、10%唑草酮WP、35%氯吡嘧磺隆WG、20%氯氟吡氧乙酸EC、2%吡草醚EC对猪殃殃的株防效均在90%以上;3%甲基二磺隆OD、50 g/L双氟磺草胺SC、56%2甲4氯钠SP对大野豌豆的株防效均在90%以上;2%吡草醚EC、20%氯氟吡氧乙酸EC、4%啶磺草胺OD、50 g/L双氟磺草胺SC、80%唑嘧磺草胺WG、35%氯吡嘧磺隆WG对小麦田总阔叶杂草的株防效在80%以上,对其鲜重防效在95%以上,在供试除草剂中防效较高。In order to screen out the suitable herbicides to control of broadleaf weeds,foliage spraying was to compare the control effect of 10 commonly used herbicides in the wheat field.At 18 days after application,pyraflufen-ethyl 2%EC provide above 90%control of Cerastium vis-cosum L,and the same as carfentrazone-ethyl 10%WP and pyroxsulam 4%OD to Galium aparine;The 10 herbicides all provide below 70%control of Vicia gigantea;And pyraflufen-ethyl 2%EC just provide 72.67%control of total weeds,but other herbicides provide less than 60%control of total weeds.At 34 days after application,the control efficacy of pyroxsulam 4%OD,MCPA-Na 56%SP,flumetsulam 80%WG,fluroxypyr 20%EC and pyraflufen-ethyl 2%EC based on plant of C.viscosum was over 90%.The control efficacy of florasulam 50 g/L SC,carfen-trazone-ethyl 10%WP,halosulfuron-methyl 35%WG,fluroxypyr 20%EC and pyraflufen-ethyl 2%EC based on plant of G.spurium was more than 90%.The control efficacy of mesosulfuron-methyl 3%OD,florasulam 50 g/L SC and MCPA-Na 56%SP based on plant V.gigantea was more than 90%.The control efficacy of pyraflufen-ethyl 2%EC,fluroxypyr 20%EC,pyroxsu-lam 4%OD,florasulam 50 g/L SC,35%halosulfuron-methyl WG and flumetsulam 80%WG based on the total number of broadleaf weeds in wheat field was more than 80%,and more than 95%based on fresh weight,which were the highest among the herbicides tested.
