Herbicidal composition containing pinoxaden and pyroxsulam

technical field [0001] The invention relates to a composition containing pinoxaden and pyrisulfame, which uses pinoxaden and pyrisulfame as active ingredients, and is used for preventing and controlling annual grasses and some broad-leaved weeds in winter wheat fields. Background technique [0002] Chemical weeding is one of the main means of controlling weeds in agriculture. In recent years, due to the large-scale single use of some herbicide varieties, many weeds have developed resistance. At the same time, when weeds occur, the grass phase is complex, grass weeds, broad-leaved weeds, and sedges are mixed, and the use of a single herbicide cannot solve farmland weeds, and all will show some defects and limitation. Mixing different types of herbicides has the advantages of broad herbicidal spectrum, improving the actual effect, delaying weed resistance, saving time and labor, etc. [0003] Pinoxaden is a new phenylpyrazoline herbicide with systemic conductivity.
