Monosulfuron-clodinafop-propargyl ester weeding composition

Abstract

The invention discloses a monosulfuron-clodinafop-propargyl ester weeding composition. The monosulfuron-clodinafop-propargyl ester weeding composition comprises monosulfuron and clodinafop-propargyl ester as active components and the balance a pesticide assistant. A mass part ratio of monosulfuron to clodinafop-propargyl ester is in a range of 1: 5 to 5: 1, and the total mass of monosulfuron and clodinafop-propargyl ester is 5-60% that of the monosulfuron-clodinafop-propargyl ester weeding composition. According to application demands, the monosulfuron-clodinafop-propargyl ester weeding composition can be processed to form a dispersible oil suspending agent, a suspending agent, wettable powder or water dispersible granules, can be used for preventing and removing gramineous weeds and broadleaved weeds in the wheat field, has weed prevention and removal effects obviously superior to those of various single-component agents, reduces a herbicide use amount and delays herbicide resistance of weeds.

Description

technical field [0001] The invention belongs to the herbicidal composition of pesticides, in particular to a herbicidal composition containing monosulfuron-methyl and clodinafop-propargyl, which are used as active ingredients to prevent and control gramineous grasses and broadleaf in wheat fields weeds. 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, and saving time and labor. [0003] Monosulfuron-methyl is a new type of sulfonylur...
