[目的]明确33%草甘膦·精喹禾灵·乙羧氟草醚可分散油悬浮剂对非耕地杂草的最佳使用剂量。[方法]采用田间药效试验研究33%草甘膦·精喹禾灵·乙羧氟草醚可分散油悬浮剂对非耕地杂草的防除效果。[结果]33%草甘膦·精喹禾灵·乙羧氟草醚可分散油悬浮剂200.0~400.0 g/hm2对非耕地杂草有明显的防除效果,茎叶喷雾处理15 d后对试验地杂草的株防效达87.53%~92.92%,35 d后平均鲜重防效达88.37%~93.89%。[结论]在单子叶杂草大部分6~8叶、阔叶杂草10~12叶时采用该制剂进行茎叶喷雾,用量为有效成分990.0~1 980.0 g/hm2(制剂量3 000.0~6 000.0 g/hm2)。
[Objective] The optimal dosages of 33% glyphosate and quizalofop-p-fluoxetine dispersible oil suspending agent for non-crop weeds were determined. [Method] The control effect of 33% glyphosate / quizalofop-p-fluoxetine dispersible oil SC on non-cultivated weeds was studied by field efficacy test. [Result] The control effect of 33% glyphosate and quizalofop-p-fluoxetine dispersible oil suspending agent 200.0-400.0 g / hm2 on non-cultivated land weeds was obvious. After spray treatment for 15 days, The weed control efficacy reached 87.53% ~ 92.92%. After 35 days, the average fresh weight control efficiency reached 88.37% ~ 93.89%. [Conclusion] Spraying stem leaves with most of 6-8 leaves of monocotyledonous weeds and 10-12 leaves of broad-leaved weeds was the best. The dosage was 990.0-1 980.0 g / hm2 000.0 g / hm2).
