Problems solved by technology

[0004] The single use of a certain herbicide is often subject to strict pre-emergence or post-emergence selection, and the scope of use is limited. Moreover, long-term use of a certain herbicide will produce resistance, and the herbicide spectrum is narrow, which seriously affects the use effect.
Compounding different types of herbicides is a common method in this field. However, the type and proportion of the compounding seriously affect the herbicidal effect of the compound herbicide. At present, there is no compound herbicide including fentrazone and thifensulfuron-methyl report

Abstract

The invention belongs to the technical field of pesticides, and provides a mixed herbicide prepared from benzene carfentrazone-ethyl and thifensulfuron methyl and application of the mixed herbicide. The benzene carfentrazone-ethyl and the thifensulfuron methyl are taken as main effective components of the mixed herbicide; wherein the mass ratio of the benzene carfentrazone-ethyl to the thifensulfuron methyl is (1:900)-(900:1). The application of the mixed herbicide in weeding of a corn field, especially the application in prevention and weeding of various grass families, the sedge family and wide leaf weeds already unearthed or about to be unearthed, has a remarkable effect. Relative to a mono-agent, the herbicide delays the resistance of weeds, and is wide in weeding spectrum, long in lasting period and safe to corns under the premise of improving the pesticide effect.

Description

Technical field [0001] The invention belongs to the technical field of pesticides, and relates to a mixed herbicide comprising carfentrazone and thifensulfuron and its application. Background technique [0002] Topramezone, also known as: Topramezone, chemical name Chemical name: [3-(4,5-dihydro-1,2-oxazol-3-yl)-4-formyl 0 -Tolyl](5-hydroxy-1-methylpyrazol-4-yl)methanone. Carfentrazone is a new hydroxyphenylpyruvate dioxidase inhibitor (HPPD) herbicide, a broad-spectrum post-emergence herbicide, which can effectively control annual grass and broadleaf weeds and cyperaceae weeds in corn fields . . Carfentrazone has a certain activity on weeds that have not been unearthed or will be unearthed, but the activity is affected by its concentration and soil organic matter content. Its degradation speed in the environment varies with soil and water conditions, and high temperature and ultraviolet light will accelerate It degrades. . [0003] Thifensulfuon (methyl), chemical name: 3-(4...
