摘　　要：应用2种除草剂对草原黄帚橐吾(Ligularia virgaurea)进行了防除试验。结果表明,迈士通用药量500.0mL/hm2对黄帚橐吾的防除效果达到80%以上,药效明显高于排草丹和迈士通的另外2个剂量;排草丹的防除效果欠佳,但对大部分禾本科和莎草科牧草安全。因此,迈士通用药量500.0 mL/hm2适宜作为防除黄帚橐吾的有效药剂推广使用。Two kinds of herbicide were used to control Ligularia virgaurea in grassland. The results showed that the control rate of Milestone at the dose of 500.0 mL/hm2 on L. virgaurea in grassland was more than 80%, which was significantly higher than that with other two doses of Milestone and Bentazone. The control effect of Bentazone was worse and it was safe to most Gramineae and Cyperaceae grass. Milestone at the dose of 500.0 mL/hm2 could be used and popularized as an effective medicament against L.virgaurea.
