摘　　要：为筛选出适宜的茎叶处理除草剂,通过大田小区试验,采用茎叶喷雾处理,对比分析15种茎叶处理除草剂对小麦安全性和杂草防除效果。结果表明,10%唑草酮可湿性粉剂(WP)出现药害,但对小麦新叶没有影响。田间药效结果显示,3.6%二磺·甲碘隆水分散粒剂(WG)、50%异丙隆WP、10%唑草酮WP、25%绿麦隆WP、41%氟噻草胺悬浮剂(SC)、20%啶磺·氟氯酯WG、50%吡氟酰草胺WG、25%噻吩磺隆WP和42%二甲·氯氟吡乳油(EC)对禾本科杂草防效较好,且持效期较长,株防效和鲜重防效均在80%以上;50%吡氟酰草胺WG、10%唑草酮WP、53%二甲四氯二甲胺盐水剂(AS)、25%绿麦隆WP、15%炔草酯水乳剂(EW)和42%二甲·氯氟吡EC对阔叶杂草防效较好,且持效期较长,株防效和鲜重防效也均在80%以上;50%吡氟酰草胺WG、10%唑草酮WP、25%绿麦隆WP和42%二甲·氯氟吡EC对禾本科和阔叶杂草均有较好的防效,药后45 d株防效和鲜重防效均超过90%,可作为茎叶处理除草剂用于麦田杂草防除。In order to select suitable herbicides for stem and leaf treatment,the safety of wheat and weed control effects of 15 kinds of stem and leaf treatment herbicides were compared and analyzed by using stem and leaf spray treatment in field plot experiment.The re⁃sults showed that 10%carfentrazone-ethyl wettable powder(WP)was harmful to wheat,but had no effect on new leaves of wheat.Field efficacy results showed that 3.6%mesosulfuron-methyl·iodosulfuron-methyl-sodium water dispersible granule(WG),50%iso⁃proturon WP,10%carfentrazone-ethyl WP,25%chlorotoluron WP,41%flufenacet suspension(SC),20%pyroxsulam·halauxifenmethyl WG,50%diflufenican WG,25%thifensulfuron methyl WP and 42%MCPA-isooctyl·fluroxypyr emulsifiable concentrate(EC)had better control effects on gramineous weeds,and the persistence was longer.The plant control effect and fresh weight control effect were both above 80%.50%diflufenican WG,10%carfentrazone-ethyl WP,53%2-methyl-4-chlorophenoxyacetic acid-dimethyl⁃amine salt aqueous solutions(AS),25%chlorotoluron WP,15%clodinafop-propargyl emulsion in water(EW)and 42%MCPA-iso⁃octyl·fluroxypyr EC had better control effect on broadleaved weeds,and the persistence was longer.The plant control effect and fresh weight control effect on weeds were more than 80%.50%diflufenican WG,10%carfentrazone-ethyl WP,25%chlorotoluron WP and 42%MCPA-isooctyl·fluroxypyr EC had good control effects on gramineous and broadleaved weeds,and the plant control effects of 45 days after treatment and fresh weight control effects were more than 90%,which could be used as stem and leaf treatment herbicides for weed control in wheat fields.
