摘　　要：为明确108 g/L高效氟吡甲禾灵乳油对春油菜田野燕麦的防除效果及其使用的安全性,在田间设108 g/L高效氟吡甲禾灵乳油每公顷277.78、347.22、416.67、694.35 g 4个处理,以108 g/L高效盖草能375.00 g/hm2为对照药剂,以人工锄草和清水喷雾为对照,于春油菜3叶至5叶1心期、野燕麦2叶1心至4叶1心期对水300 L喷雾处理,药后观察油菜和杂草生长情况、调查防效。结果表明,108 g/L高效氟吡甲禾灵乳油对春油菜田野燕麦具有良好防效,适宜用量为416.67 g/hm2,对野燕麦鲜重防效达到86.10%,对作物安全,油菜增产9.80%。108 g/L高效氟吡甲禾灵乳油是防除春油菜田野燕麦的优良除草剂,可以在生产上推广使用。The study of the control efficacy of 108 g/L haloxyfop-R-methyl EC against Avena fatua L. was revealed, as well as its safety in spring rape fields. The treatment included 277.78, 347.22, 416.67 and 694.35 g/hm2 of 108 g/L haloxyfop- R-methyl EC. The 375.00 g/hm2 of 108 g/L haloxyfop-R-methyl EC was used as herbicide control, and manual weeding and water were regarded as negative control. These herbicides were sprayed during 3-5 leaf stage of rape with 300 L water （2-4 leaf stage of A. fatua L.）.The incidence of weeds was investigated on the 20th and 40th days after spraying for calculating the control effect. The results showed that haloxyfop-R-methyl EC preformed well in controlling A. fatua L., and the suitable dosag was 416.67 g/hm2. It was safe in spring fields, and the control effect on A. fatua L. reached 86.10%, yield increased by 9.80%. Haloxyfop-R-methyl EC effectively controlled A. fatua L. and could be used widely in spring rape fields.
