Abstract

The invention provides a herbicide composition which takes glufosinate and oxadiazon as active components, wherein the weight ratio of the glufosinate to the oxadiazon is 1 to 99:99 to 1. The invention also provides an application of the herbicide composition in the aspects of preventing and removing annual and perennial broadleaf weed and grassy weed. Compared with a single agent, the weeding effect of the herbicide composition is obviously enhanced, and the herbicide composition puts up a very good synergistic action, lowers the use quantity of a medicament, reduces the application cost of a farmer and also lowers the influence to the environment; and meanwhile, the weed control spectrum is expanded, and the generation and the development of the resistibility of the single agent can be effectively delayed.

Description

technical field [0001] The invention relates to the field of agricultural herbicides, in particular to a herbicide composition with glufosinate-ammonium and oxadiazon as active ingredients and an application thereof. Background technique [0002] Glufosinate-ammonium is an organophosphorus non-conductive herbicide targeting glutamine synthetase (GS). It has broad-spectrum herbicidal activity and is widely used for weed control of rapeseed, corn, cotton, soybean and rice. [0003] The chemical name of glufosinate-ammonium is 4-[hydroxy(methyl)phosphono]-DL-homoalanine or 2-amino-4-[hydroxy(methyl)phosphono]ammonium butyrate, and its molecular formula is C 5 h 15 N 2 o 4 P, the molecular weight is 198.2, and the structural formula is: [0004] [0005] The molecular structure of glufosinate-ammonium has two optical structures, L-type and D-type, of which the L-type is the biologically active structure; the D-type has no biological activity, and the glufosinate-ammonium ...
