Abstract

The invention relates to a weeding composition containing carfentrazone-ethyl and diflufenican. The weeding composition is mainly characterized by comprising 1-60 percent of carfentrazone-ethyl and 1-80 percent of diflufenican serving as active ingredients, an aid and other excipients and being prepared into wettable powder, water-dispersible granules, a suspending agent, a micro-emulsion, an aqueous emulsion and the like. The weeding composition is used for preventing and controlling wheatfield broadleaf weeds, gramineae weeds and sedges.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a herbicidal composition containing mefentrazone and diflufenican, which is used for preventing and treating broad-leaved weeds, gramineous weeds and sedges 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] Carfentrazone-ethyl, molecular formula: C 15 h 14 Cl 2 f 3 N 3 o 3 , chemical name: ethyl-2-chloro-3-{2-chloro-5-[4-(difluoromethyl)-4,5-dihydro-3-methyl-5-oxo-1H-1, ...
