Problems solved by technology

[0009] At present, herbicides in soybean fields are limited by crop safety and herbicidal spectrum is also limited. Using a single herbicide alone cannot completely and effectively control the occurrence of weeds in soybean fields In addition, some herbicides are likely to cause residual toxicity to current crops or subsequent crops due to their high water solubility or long field duration, excessive dosage or uneven application.
The inventors have found through research that the synergistic compounding of herbicides is an effective measure to expand the weed control spectrum and improve the control effect. So far, no herbicidal composition related to the compounding of glufosinate-ammonium and chlorester-sulam has been found.

Abstract

The invention discloses weeding composition containing glufosinate-ammonium and cloransulam-methyl and an application of the weeding composition. The weeding composition contains glufosinate-ammoniumand cloransulam-methyl as main effective components, and the mass ratio of glufosinate-ammonium to cloransulam-methyl is 1:60-60:1. The weeding composition can be used for post-emergence weeding of asoybean field and particularly has remarkable effect on controlling and eliminating gramineous and broadleaf weed in the soybean field. The weeding composition has the advantages that on the premise that the efficacy is improved as compared with single herbicide, weed resistance is delayed, the weed control spectrum is wide, the lasting period is long, and the weeding composition is safe to soybeans and succeeding 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 cloxazone-sulam, which can be applied to post-emergence weeding in soybean fields. Background technique [0002] Glufosinate-ammonium. Chemical name: 4-[hydroxy(methyl)phosphono]-DL-homoalanine, structural formula: [0003] [0004] 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 metabol...
