Abstract

The invention discloses a compound weeding composition containing glufosinate-ammonium. The compound weeding composition comprises, by weight, 5 to 80% of active components consisting of glufosinate-ammonium and clomeprop in a weight ratio of 1: 20 to 20: 1, with the balance being auxiliary agents. The dosage form of the compound weeding composition may be a wettable powder, a water dispersible granule, a suspension concentrate, an oil concentrate, etc. The compound weeding composition can compensate for the defect that single glufosinate-ammonium has poor effect on cyperaceous drug-resistant weeds like Cyperus rotundus and the defect that single clomeprop can only control broadleaf weeds and cyperaceous weeds and almost has no effect on gramineous weeds, and is capable of effectively preventing and eliminating weeds; and the two above active components in a certain ratio range present synergistic effect and exert better effect compared with single glufosinate-ammonium and single clomeprop, so the dosage of pesticides is reduced, adverse impact of pesticides on ecological environment is lowered, and good prevention effect is exerted on gramineous weeds like Cyperus rotundus which is hard to prevent and eliminate with glufosinate-ammonium.

Description

technical field [0001] The invention relates to a herbicidal composition, in particular to a compound herbicidal composition containing glufosinate-ammonium, belonging to the field of pesticide preparations, and the herbicidal composition is used for controlling weeds in non-arable land. Background technique [0002] The use of chemical control methods to weed control is one of the main means of controlling weeds in agriculture and forestry. Especially in forestry, orchards, non-farmland and no-tillage fields, the selection of herbicides can effectively control a variety of annual or perennial weeds and save labor costs. At present, the main herbicides used are glyphosate, paraquat, etc., but due to the single and large-scale use in recent years, the weed resistance is getting higher and higher, and the dosage is also increasing. The emergence of weeds, glyphosate and paraquat have certain limitations in the use process. [0003] Glufosinate-ammonium is a non-selective, br...
