摘要
为了更好地防除春油菜田野燕麦,对10.8%精喹禾灵乳油防除春油菜田野燕麦的效果及其对春油菜的安全性进行了田间小区试验。结果表明,10.8%精喹禾灵乳油在一定剂量范围内于野燕麦3～4叶期(春油菜3～4叶期)兑水300 L/hm2茎叶喷雾,对野燕麦的防除效果达到66.24%～95.75%,各处理区油菜生长正常。10.8%精喹禾灵乳油安全性好、防效高、持效期长。
In order to better control wild oats （Avena fatua L. ） weeds in spring rape field, field plot experiments concerning effect of 10.8% quizalofop - p - ethyl EC on weeds control and its safety to spring rape were carried out. The results showed that, within a reasonable dosage extent, using of 10.8% quizalofop - p - ethyl EC added with 300L/hm2 water to spray the stems and leaves of wild oats. At the stage of 3 -4 leaves（i, g. 3 -4 leaves stage spring rape）, wild oats con- troUling effects could reach to 66.24%^-95.75%, and the spring rape, growed nomally in all testing plots. 10.8% quizalofop - p - ethyl EC has been proved to have high safety, good high controlling effects, and a long period of validity.
