Herbicidal composition containing pinoxaden and pyroxsulam

Abstract

The invention discloses a herbicidal composition containing pinoxaden and pyroxsulam. The herbicidal composition comprises the active components pinoxaden and pyroxsulam, and the balance pesticide adjuvants. The pinoxaden and the pyroxsulam are in a mass part ratio of 1:5-5:1, and the total mass of the pinoxaden and the pyroxsulam accounts for 5%-70% of the mass of the herbicidal compositionAccording to the needs of the application, the herbicidal composition provided by the invention can be prepared into one form of dispersible oil suspension agent, suspending agent, wettable powder, and water dispersible granule to prevent and kill off annual gramineae and part of broadleaf weeds in winter wheat field. The composition has significantly better effects of preventing and killing off annual gramineae and part of broadleaf weeds in winter wheat field, the drug dosage is reduced, and the weed resistance to drugs is delayed.

Description

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. The mec...
