Problems solved by technology

[0009] At present, herbicides in non-cultivated land, orchards and paddy fields are limited by crop safety, and the herbicidal spectrum is also limited. Using a single herbicide alone cannot completely 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 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 tetrazolium has been found so far.

Abstract

The invention discloses a weeding composition containing glufosinate-ammonium and fentrazamide and application thereof. The weeding composition uses glufosinate-ammonium and fentrazamide as main active components, and a mass ratio of glufosinate-ammonium to fentrazamide is 1: 60 to 60: 1. The weeding composition is applicable to weeding in uncultivated areas, orchards and paddy fields and especially has substantial prevention and treatment effect on graminaceous and broad-leaf weeds in uncultivated areas, orchards and paddy fields. Compared with a separate usage of glufosinate-ammonium and fentrazamide, the weeding composition of the invention has the advantage of capacity of delaying weed resistance, wide weeding spectrum, long action duration and safety to fruit trees, rice and later crops on the premise of improvement of weeding effect.

Description

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