Problems solved by technology

The types of weeds on ridges are qualitatively different from weeds in wheat fields and rice fields, and the growth environment is completely different from weeds in wheat fields and rice fields. At present, glyphosate and paraquat are often used as the main herbicides, but these herbicides are easy to damage seedlings. loss to farmers

Abstract

The invention relates to a herbicide, wherein the weight ratio of bensulfuron methyl to isoproturon is (0-15):(45-100). The herbicide can be prepared to wettable powder, suspending agent, water dispersing granule and so on. When the herbicide is applied to control weed in the crop land ridge, the herbicide does not cause crop hurting or killing phenomenon which always happens when the frequently used herbicides glyphosate and paraquat are sprayed, and at the same time, the herbicide reduces the hurt to lungs after a user sprays paraquat herbicides.

Description

technical field [0001] The invention relates to a herbicide and its application, belonging to the technical field of pesticides. Background technique [0002] Isoproturon (isoproturon), trade name isoproturon, chemical name is N-4 isopropyl-N', N'-dimethylurea. This product was previously developed by the German company Hested, and domestically produced by Jiangsu Changlong Chemical Factory. The grass spectrum is narrow. [0003] Bensulfuron-methyl (Pyrqzosulfuron), trade name bensulfuron-methyl, chemical name 2-(((4,6-dimethoxypyrimidin-2-yl)aminocarbonylamino)sulfonylmethyl)benzoic acid methyl ester. This product is domestically produced by Changlong Chemical Co., Ltd., and belongs to the sulfonylurea herbicides, which are often used to control weeds in paddy fields. [0004] CN101971845A discloses a compound herbicide of isoproturon-methyl and bensulfuron-methyl, the herbicide is a wettable powder, wherein the weight ratio of the active ingredients bensulfuron-methyl ...
