Problems solved by technology

[0007] At present, herbicides in cornfields are limited by the safety of crops, and their herbicidal spectrum is also limited. Using a single herbicide alone cannot completely and effectively control the occurrence of weeds in cornfields. Too long effective period, excessive dosage or uneven application will easily cause residual toxicity to current crops or subsequent crops
The inventor found through research that the synergistic compounding of herbicides is an effective measure to expand the weed control spectrum and improve the control effect, and no herbicidal composition related to the compounding of glufosinate-ammonium and chlorpyrazosulfuron-methyl has been found so far.

Abstract

The invention discloses weeding composition containing glufosinate and halosulfuron-methyl and an application of the weeding composition. The weeding composition is prepared from main effective ingredients including glufosinate and halosulfuron-methyl in the mass ratio being (1:60)-(60:1). The weeding composition can be used for post-emergence weeding in a corn field and particularly has a remarkable effect when used for controlling gramineous and broadleaf weeds in the corn field. Compared with a single agent, the weeding composition delays weeding of weeds, has a broad weed control spectrum and has a long lasting period on the premise that the efficacy is improved and is safe to corn and succession crops.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to the field of herbicides, and specifically relates to a binary compound herbicidal composition containing glufosinate-ammonium and chlorpyrazosulfuron-methyl, which can be applied to post-emergence weeding in corn fields. Background technique [0002] Glufosinate-ammonium. Chemical name: 4-[hydroxy(methyl)phosphono]-DL-homoalanine. [0003] Glufosinate-ammonium, also known as glufosinate, is a non-selective foliar sprayed organophosphate herbicide, which was first synthesized and developed by the Federal German Hoechst Chemical Company in 1979. The herbicidal action mechanism of glufosinate-ammonium is that after absorption by the leaves, it has a partial systemic effect, and can be transferred from the base of the leaves to the ends, less transferred to other parts of the plant, and is harmless to unearthed young shoots and seeds. The ammonium metabolism in the plant is in d...
