摘　　要：为了更好地防治春油菜田野燕麦杂草，在青海省农牧交错区对120g/L烯草酮EC防除春油菜田野燕麦的效果及其对作物的安全性进行田间小区试验。试验结果表明：120g/L烯草酮EC不同制剂量于野燕麦4～7叶期（春油菜4—6叶期）兑水300L／hm2茎叶喷雾，对野燕麦的防除效果达到74．66％-87．93％，各处理区油菜生长正常。120g/L烯草酮EC安全性好、防效高、持效期长，可在青海高原农牧交错区进一步示范推广。The research aimed to control wild oats better in spring planting rape field. The field plot experiment with 120 g/L clethodim EC was carried in Qinghai farming-pastoral areas to study the control effect and safety of that herbicide. When the different dose of 120 g/L clethodim EC was sprayed during 4-7 leaves in wild oats （i.e.4-6 leaves in spring planting rape）, the control effect reached 74.66%-87.93% and was equivalent to that of clethodim 5% EC, After herbicide application, spring planting rape got the normal growth in each treatment area. With the advantages of safety, good control effect and long action cycle, 120 g/L clethodim EC could be generalized in spring planting rape field of Qinghai farming-pastoral areas.
