Problems solved by technology

[0004] At present, herbicides in wheat fields are limited by the safety of crops, and their herbicidal spectrum is also limited. Using a single herbicide alone cannot completely and effectively control the occurrence of weeds in wheat fields. If the effective period is too short, the dosage is too large or the application is uneven, it will easily cause residual toxicity to the crops of the current season or the subsequent crops.

Abstract

The invention discloses mixed herbicide containing pyrasulfotole and pinoxaden, the mixed herbicide takes the pyrasulfotole and the pinoxaden as main effective components, and the mass ratio of the pyrasulfotole to the pinoxaden is (1 to 68):(1 to 68). The mixed herbicide disclosed by the invention has the advantages of broad spectrum, quick result, high efficiency, low toxicity, safety and environmental protection, and the like when being applied to post-seedling weeding of a wheat field.

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 sulfoxaden and pinoxaden. 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 a...
