Abstract

The invention relates to a weeding composition containing beflubutamid and pyraflufen-ethyl. The weeding composition is mainly characterized by comprising 1-70 percent of active ingredient beflubutamid, 1-40 percent of pyraflufenethyl, an aid and other excipients, and is prepared into wettable powder, water dispersible granules, suspension agents, suspension emulsions, micro emulsions, aqueous emulsions and the like. The weeding composition is used for preventing and controlling weeds in cornfields.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a herbicidal composition containing fluorinated butyramid and metazafen, which is used for preventing and controlling weeds in wheat fields. Background technique [0002] In 1955, it was reported that Herbicide could increase the control effect of thatch quat on Limegrass. Later, with the further development of herbicide production and application, the mixed use of herbicides gradually developed. my country also pays more attention to the research on the mixed use of herbicides, which is widely regarded as one of the important measures for the rational use of herbicides. A series of herbicide mixtures have been developed and great progress has been made. [0003] Beflubufamid (beflubufamid), molecular formula: C 18 h 17 f 4 NO 2 , molecular weight: 355.33. Flubutyramide is a phenoxyamide herbicide developed by Japan Ube Industrial Co., Ltd. It is mainly used f...
