Abstract

The invention discloses a mixed herbicide containing pyrasulfotole and fluoroglycofen. The herbicide takes pyrasulfotole and fluoroglycofen as main active ingredients, wherein the mass ratio of pyrasulfotole to fluoroglycofen is (1-68) to (1-68). The mixed herbicide has the advantages of broad spectrum, quick action, high efficiency, low toxicity, safety, environment friendliness, and the like when being applied to post-emergence weed control in wheat fields.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to the field of herbicides, and relates to a binary compound of pyrazole sulfonate and acifluorfen. The herbicide composition can be used for post-emergence weeding in wheat fields. Background technique [0002] Pyrasulfotole, chemical name: (5-hydroxy-1,3-dimethylpyrazol-4-yl) (α,α,α-trifluoro-2-methanesulfonyl-p-toluene Base) ketone, structural formula is: Sulpyrazole is a new type of herbicide discovered by Bayer Crop Science in 1999. It belongs to the benzoylpyrazole compound and is an HPPD inhibitor. Inhibition of HPPD indirectly inhibits carotenoid biosynthesis, resulting in albinism of plant meristems and eventually death. This herbicide has broad-spectrum herbicidal activity and can be used both before and after emergence. Due to the long-term use of sulfonylurea herbicides in wheat fields to control broad-leaved weeds, many resistant broad-leaved weeds have appeared ...
