Abstract

The invention relates to a weeding composition and application thereof. The weeding composition is a composition containing flumioxazin and quinclorac, and is preferably wettable powder containing quinclorac and flumioxazin. The weeding composition is used for pre-emergence sealing treatment of cotton fields to prevent and remove graminaceous weeds and broadleaf weeds, and is remarkable in synergistic and yield-increasing effect.

Description

technical field [0001] The invention belongs to the field of agricultural herbicides, and relates to a wettable powder containing quinclorac and flufluramid. Background technique [0002] Flumioxazin, chemical name N-(7-fluoro-3,4-dihydro-3-oxo-4-propyn-2-yl-2H-1,4-benzoxazine -6-yl) cyclohexen-1-yl-1,2-dicarboxamide, the CAS number is 103361-09-7, and the structural formula is as follows: [0003] [0004] Flurafen propargyl is an N-phenylphthalimide herbicide created and developed by Sumitomo Chemical Industry Co., Ltd., Japan. It can inhibit protoporphyrinogen oxidase, leading to photosensitization and peroxidation of cell membrane lipids, causing irreversible damage to the co-tender structure of cell membranes. In the field, the stems and leaves of sensitive weeds are necrotic after stems and leaves are treated, and they die after sunlight exposure , sensitive weed shoots were necrotic after soil treatment, and died after brief exposure to sunlight. [0005] Quincl...
