Abstract

The invention discloses a weeding composition containing glufosinate-ammonium and sulfonylurea herbicides. The weeding composition comprises glufosinate-ammonium an active ingredient A and an active ingredient B. A weight ratio of the ingredient A to the ingredient B is 200: 1 to 1: 1. The active ingredient B comprises a sulfonylurea compound with a structural formula (I). The weeding composition comprises 5-80wt% of the active ingredients and the balance auxiliary agents. The weeding composition can be processed to form wettable powder, water dispersible granules, a water suspending agent and an oil suspending agent, can be used for preventing and removing weeds, has effects better than that of single glufosinate-ammonium or active ingredient B, reduces a pesticide usage dosage, reduces pesticide-caused unfavorable influence on the ecological environment, has good preventing effects on cyperaceous weeds such as Cyperus rotundus difficultly removed by glufosinate-ammonium and can effectively treat weed resistance to herbicides.

Description

technical field [0001] The invention relates to a herbicidal composition, in particular to a herbicidal composition containing glufosinate-ammonium and a sulfonylurea herbicide, 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...
