Abstract

The invention relates to a weeding composite containing carfentrazone-ethyl and pyraflufen-ethyl. The weeding composite is mainly characterized by containing the following active ingredients: 1-60 percent of carfentrazone-ethyl, 1-60 percent of pyraflufen-ethyl, auxiliaries and other excipients; and the weeding composite can be prepared into wettable powder, water dispersible granule, suspending agent, microemulsion, aqueous emulsion and the like. The weeding composite is used for preventing and controlling board-leaf weeds and nutgrass flatsedge in wheat field.

Description

Technical field [0001] The invention belongs to the technical field of pesticides, and specifically relates to a herbicidal composition containing carfentrazone and metazachlor, which is used for controlling broadleaf weeds and sedges in wheat fields. Background technique [0002] In 1955, it was reported that the herbicide potency increased the control effect of thatch grass on stone grass. Later, with the further development of herbicide production and application, the mixing of herbicides gradually developed. my country also pays more attention to the research of herbicide mixed use, 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-oxy-1H-1, 2,4-Triazol-1-yl]-4-fluorophenyl} ethyl propion...
