摘　　要：为筛选出对麦田恶性杂草猪殃殃防效较好的药剂,对17种除草剂开展了温室盆栽试验和田间小区试验。温室盆栽试验中,200g·L^(-1)氯氟吡氧乙酸乳油和25%灭草松水剂对猪殃殃有较好的抑制作用,试验剂量下鲜重抑制率均达100.00%。田间小区试验中,对猪殃殃防效最好的是80%唑嘧磺草胺水分散粒剂,用药25.00g(a.i)·hm^(-2)后30d对猪殃殃的株数防效为85.08%,药后60d的株数防效和鲜重防效则达100.00%;其次为50g·L^(-1)双氟磺草胺悬浮剂、200g·L^(-1)氯氟吡氧乙酸乳油。To evaluate herbicide efficacy against Galium aparina L.,whole-plant dose response experiment and field plot experiment were conducted with 17 herbicides selected.It was shown that 200g·L^（-1） fluroxypyr EC and 25% bentazone AS gave very good control of Galium aparina L.with100.00%fresh weight inhibition at setting doses.80% flumetsulam WG was the best in controlling Galium aparina L.in field plot experiment with 85.08% plant reduction after 30 days and 100.00%reduction after 60 days at 25.00g（a.i）·hm-2.50g·L^（-1） florasulam SC and 200g·L^（-1） fluroxypyr EC showed lower reduction than flumetsulam.
