Problems solved by technology

[0007] At present, herbicides in non-cultivated land, orchards and paddy fields are limited by the safety of crops, and the herbicidal spectrum is also limited. Using a single herbicide alone cannot completely and effectively control the occurrence of weeds in wheat fields. Moreover, some herbicides are water-soluble High resistance or long duration in the field, excessive dosage or uneven application will easily cause residual toxicity to current crops or subsequent crops
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 bisacenil has been found.

Abstract

The invention discloses herbicidal composition containing glufosinate-ammonium and pyraclonil and an application of the herbicidal composition. The herbicidal composition takes glufosinate-ammonium and pyraclonil as main effective ingredients, wherein the mass ratio of glufosinate-ammonium to pyraclonil is (1:60)-(60:1). The herbicidal composition can be used for weeding of the uncultivated area,the orchard and the paddy field and particularly has a remarkable effect on control of grassy weed broadleaf weed in the uncultivated area, the orchard and the paddy field. Compared with single agents, the herbicidal composition delays the weed resistance, has wide weeding spectrum and long lasting period and is safe to rice, fruit trees and afterreap crops on the premise that the efficacy is improved.

Description

technical field [0001] The invention belongs to the technical field of pesticides, especially the field of herbicides, and specifically relates to a binary compound herbicidal composition containing glufosinate-ammonium and dipacenil, which can be applied to weeding in non-cultivated land, orchards and paddy 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 ...
