Abstract

The invention discloses a weeding composition containing pinoxaden and triclopyr and application of the weeding composition. The weeding composition comprises the following active components: pinoxaden and triclopyr in a mass ratio of 1: 60 to 60: 1, preferably 1: 30 to 30: 1. The dosage form of the weeding composition may be missible oil, a suspending agent, an emulsion in water, a dispersible oil suspending agent, wettable powder, water dispersible granules and a dry suspending agent. The weeding composition is mainly used for preventing and treating annual gramineous weeds and various broadleaf weeds in wheat fields, has a remarkable synergistic effect, shows a prevention effect obviously better than the prevention effect of a single agent, is high in wheat safety and meets the safety requirements of pesticide preparations.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a herbicidal composition compounded with pinoxaden and clopyroxyacetic acid, which is used for post-emergence stem and leaf treatment of wheat fields to prevent and control gramineous and broad-leaved weeds. Background technique [0002] Pinoxaden, chemical name: 2,2-dimethyl-propiolic acid 8-(2,6-diethyl-4-methyl-phenyl)-9-oxo-1,2, 4,5-4Hydro-9H-pyrazol[1,2-d][1,4,5]oxodiazepine-7-yl ester. It is a phenylpyrazoline herbicide discovered, developed and produced by Syngenta with a unique chemical structure. It inhibits the activity of acetyl-CoA carboxylase (ACCase), hinders the biosynthesis of fatty acids, interferes with the formation of cell membranes, and causes weeds to stop growing and eventually die. Pinoxaden is a selective, systemic herbicide for gramineous weeds, with high efficiency, broad spectrum, and rapid absorption through stems and leaves. 1 to 3 ...
