Problems solved by technology

[0006] At present, herbicides in wheat fields 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 wheat fields. 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 spectrum of weed control and improve the control effect. So far, no herbicidal composition related to the compounding of glufosinate-ammonium and monosulfuron-methyl has been found.

Abstract

The invention discloses a weeding composition containing glufosinate and monosulfuron and application thereof. The weeding composition takes glufosinate and monosulfuron as main active ingredients, and the mass ratio of glufosinate to monosulfuron is 1:60-60:1. The weeding composition can be used for weeding for seedlings in wheat fields and have remarkable effects when particularly used for removing grass family and broad-leaved weeds in the wheat fields. Compared with a single dosage, on the premise of improving medicine effects, the weeding composition delays weed resistance, is wide in weeding spectrum and long in lasting period and has safety for wheat 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 monosulfuron-methyl, which can be applied to post-emergence weeding in wheat 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 disorde...
