Problems solved by technology

[0009] At present, herbicides in 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 paddy fields. Too long effective period, 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 spectrum of weed control and improve the control effect. So far, no herbicidal composition related to the compounding of glufosinate-ammonium and mefenamide has been found.

Abstract

The invention discloses weeding composition containing glufosinate-ammonium and mefenacet and an application of the weeding composition. The weeding composition contains glufosinate-ammonium and mefenacet as main effective components, and the mass ratio of glufosinate-ammonium to mefenacet is 1:60-60:1. The weeding composition can be used for post-emergence weeding of a paddy field and particularly has remarkable effect on controlling and eliminating gramineous and broadleaf weed in the paddy field. The weeding composition has the advantages that on the premise that the efficacy is improved ascompared 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 rice 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 mefenacet. The herbicidal composition can be used for post-emergence weeding in 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 ammon...
