Abstract

The invention discloses a weeding composition containing amidosulfuron and pyroxsulam. The weeding composition comprises effective ingredients and a pesticide adjuvant, wherein the effective ingredients are the amidosulfuron and the pyroxsulam; the mass portion ratio of the amidosulfuron and the pyroxsulam is (1:5)-(5:1), and the mass percent of the sum of mass of the amidosulfuron and the pyroxsulam in the weeding composition is 3-94 percent. According to application requirements, the weeding composition can be prepared into one of a scattered oil suspending agent, a suspending agent, wettable powder and water dispersible granules. The weeding composition is used for preventing and killing annual weeds in winner wheat fields.

Description

technical field [0001] The invention relates to a herbicidal composition containing sulfuron-methyl and acesulfame, which is used for controlling annual 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] Acetylsulfuron-methyl belongs to the sulfonylurea herbicides and is an inhibitor of acetolactate synthase. After the weed leaves absorb the pesticide, they stop growing,...
