野燕麦是马铃薯田的主要杂草之一，人工除草工作量大。本研究的目的是明确240 g/L收乐通EC在青海省马铃薯田防除野燕麦药效、适宜剂量及对作物的安全性。在田间使用了240 g/L收乐通EC制剂量300，450，600 mL/hm2，以108 g/L高效盖草能EC制剂量375 mL/hm2为对照药，设空白对照处理，于马铃薯3~5叶期，野燕麦为3~6叶期兑水300 L/hm2喷雾处理。结果表明，240 g/L收乐通EC是马铃薯田防除野燕麦的优良除草剂，适宜剂量为450 mL/hm2，对野燕麦40 d株防效和鲜重效均达85%以上，对马铃薯安全，增产率达10%以上。

Avena fatua is one of the main weeds in potato fields, and the workload of manual weeding is high. The purpose of this study was to understand the efficacy, suitable dosage and safety of 240 g/L Selectone EC for control of Avena fatua in potato fields. The treatment included 300, 450 and 600 mL/ha of 240 g/L Selectone EC, 375 mL/ha of 108 g/L Haloxyfop-R-methyl (herbicide control), and manual weeding (blank control). These herbicides were sprayed during 3-5 leaf stage of potato with 300 L/ha water (3-6 leaf stage of A. fatua ). The results showed that 240 g/L Selectone EC was a superior herbicide. Its suitable dosage was 450 mL/ha, and plant control and fresh weight control effects 40 days after spray was al above 85% in potato field. 240 g/L Selectone EC was safe to potato and the yield of potato increased over 10% when compared with blank control.
