Ternary weeding composition containing topramezone

The invention belongs to the technical field of pesticide compounding, and particularly relates to a ternary weeding composition containing topramezone, the composition comprises effective weeding dose of active components A, B and C. The active component A is topramezone, the active component B is halauxifen-methyl, the active component C is florasulam, and the weight ratio of A to B to C is (1-10): (0.1-3): (0.1-2). The weeding composition can be prepared into a plurality of agriculturally allowable dosage forms, has a certain synergistic effect on broadleaf weeds in wheat fields, can effectively reduce the dosage of medicaments, reduces the cost, protects the environment, and can delay the generation of drug resistance of weeds. 本发明属于农药复配技术领域，具体涉及一种包含苯唑草酮的三元除草组合物，所述组合物包括除草有效量的活性成分A、B和C，其中，活性成分A为苯唑草酮，活性成分B为氟氯吡啶酯，活性成分C为双氟磺草胺，A、B和C的重量比为（1-10）：（0.1-3）：（0.1-2）。该除草组合物能制成农业上允许的多种剂型，对小麦田阔叶杂草具有一定的增效作用，可以有效降低药剂使用量，减少成本，保护环境，并且能够延缓杂草抗药性的产生。
