Weeding composition containing topramezone and clodinafop propargyl

The invention relates to a weeding composition containing topramezone and clodinafop propargyl. The weeding composition contains the active components of topramezone and clodinafop propargyl in a weight ratio of (1 to 20)-(20 to 1). Furthermore, the weeding composition and a third component form a ternary weeding composition, the third component is selected from halauxifen-methyl, florasulam or fluroxypyr, and the weight ratio of halauxifen-methyl to florasulam to fluroxypyr is (1-4) to (1-4) to (1-2). Furthermore, the weeding composition is prepared into a weeding water suspending agent. The binary or ternary weeding composition has a synergistic effect; and by selecting a specific compound surfactant, the suspensibility and long-term storage stability of the weeding water suspending agent are greatly improved. 本发明涉及种包含苯唑草酮和炔草酯的除草组合物，所述除草组合物中的活性成分为重量比为1:20~20:1的苯唑草酮与炔草酯的组合物。进步地，所述除草组合物和第三组分起组成三元除草组合物，第三组分选自氟氯吡啶酯、双氟磺草胺或氯氟吡氧乙酸，三者的重量比为1-4:1-4:1-2。更进步，所述除草组合物配制成除草水悬浮剂。本发明的二元或三元除草组合物均具有增效作用；本发明的水悬浮剂通过选择特定的复合表面活性剂
