Abstract

The invention discloses a glufosinate-aryloxyphenoxypropionic acid herbicide weeding composition. The glufosinate-aryloxyphenoxypropionic acid herbicide weeding composition comprises glufosinate and an aryloxyphenoxypropionic acid herbicide as active ingredients, and the balance pesticide assistants. A weight ratio of glufosinate to the aryloxyphenoxypropionic acid herbicide in the glufosinate-aryloxyphenoxypropionic acid herbicide weeding composition is in a range of (50: 1) to (1: 1). The glufosinate-aryloxyphenoxypropionic acid herbicide weeding composition comprises 10 to 80wt% of glufosinate and the aryloxyphenoxypropionic acid herbicide. The glufosinate-aryloxyphenoxypropionic acid herbicide weeding composition can be used for preventing and removing weeds in bare places, orchards and field ridges, has effects superior to effects of a single aryloxyphenoxypropionic acid herbicide or glufosinate, reduces a use amount of a pesticide, reduces the adverse influence produced by a pesticide on the ecological environment, and effectively solves the problem of weed resistance to pesticides.

Description

technical field [0001] The invention relates to a herbicidal composition, which uses glufosinate-ammonium and aryloxyphenoxypropionic acid compounds as active ingredients and is used for preventing weeds in non-cultivated land, orchards and farmland. Background technique [0002] Chemical weeding is one of the main means of controlling weeds in agriculture. In recent years, due to the large-scale single use of glufosinate-ammonium, many weeds have developed resistance. At the same time, when weeds occur, the grass phase is complex, not only annual and perennial weeds are mixed, herbs, vines and shrubs are mixed, but also the emergence of weeds is uneven, and the seeds, young and old weeds are staggered, so the herbicide species alone When used, all will show some defects and limitations. [0003] Glufosinate-ammonium, chemical formula: [0004] [0005] Chemical name: (RS)-2-amino-4-(hydroxymethyloxyl)ammonium butyrate, English name: glufosinate-ammonium, other Chinese...
