Abstract

The invention relates to a weeding composition containing carfentrazone-ethyl and clopyralid. The composition is mainly characterized by comprising 1-60 percent of carfentrazone-ethyl and 1-80 percent of clopyralid 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 specifically relates to a herbicidal composition containing pyropend and clopyralid, which is used to control broadleaf weeds, grass weeds and sedges in wheat fields. Background technique [0002] In 1955, it was reported that fenfossil could increase the control effect of fentanyl on dandelion. Later, with the further development of herbicide production and application, the mixed use of herbicides gradually developed. Our country also attaches great importance to the research on the mixed use of herbicides, which is widely recognized 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-oxygen-1H-1, 2,4-Triazol-1-yl]-4-fl...
