Weeding composition containing pinoxaden

The invention relates to the technical field of agriculture, in particular to a weeding composition containing pinoxaden. The weeding composition comprises (A) pinoxaden and (B) at least one stabilizer, and the at least one stabilizer comprises a tri-[C2-C6 alkyl] of phosphoric acid and/or a carbon chain isomer thereof. According to the invention, a proper stabilizer, a proper solubilizer and a proper emulsifier are screened out, so that the decomposition rate of the weeding composition can be obviously reduced; the stabilizer screened by the invention has a synergistic effect, and the biological activity of the weeding composition can be improved; and the stabilizer, the solubilizer, the emulsifier and other components contained in the weeding composition are low in toxicity or non-toxic,and the safety is good. 本发明涉及农用技术领域，具体涉及一种含有唑啉草酯的除草组合物。该除草组合物，其包括：(A)唑啉草酯；(B)至少一种稳定剂，该稳定剂包括磷酸的一种三-[C-C烷基]和/或其碳链异构体。本发明通过筛选出合适的稳定剂、增溶剂、乳化剂，可明显降低除草组合物的分解率；本发明筛选出的稳定剂兼具增效作用，能提高除草组合物的生物活性；本发明除草组合物中包含的稳定剂、增溶剂、乳化剂等成分的毒性都属于低毒或无毒，安全
