Problems solved by technology

[0008] At present, herbicides in cotton 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 cotton fields. Too long effective period, excessive dosage or uneven application will easily cause residual toxicity to current crops or subsequent crops

Abstract

The invention discloses a herbicidal composition containing trifloxysulfuron and propaquizafop and application thereof. The herbicidal composition uses trifloxysulfuron and propaquizafop as effective ingredients having a mass ratio of 1-60:1-60. The herbicidal composition is useful in post-seedling weeding of cotton fields, particularly significant in preventing and removing grassy weeds and broad-leaved weeds in cotton fields. Compared with a single agent, the herbicidal composition is higher in efficiency, can delay resistance of weeds, has wide herbicidal spectrum and long acting period, and is safe to both cotton and afterculture crops.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to the field of herbicides, and specifically relates to a herbicidal composition containing trifluxysulfuron-methyl and axaclofen-methyl and an application thereof. Background technique [0002] Trifloxysulfuron, also known as Inventor. Chemical name: 1-(4,6-dimethoxypyrimidin-2-yl)-3-[3-(2,2,2-trifluoroethoxy)-2-pyridinesulfonyl]urea, the structural formula is : [0003] [0004] Trifluxysulfuron-methyl belongs to the sulfonylurea herbicides. After application, it can be absorbed by the roots, stems and leaves of weeds, and can be transmitted downward and upward in the plant. By inhibiting the activity of acetolactate synthase (ALS), Thus affecting the biosynthesis of branched-chain amino acids (such as: leucine, isoleucine, valine, etc.). After the plant is damaged, it manifests as growth point necrosis, leaf vein chlorosis, plant growth is severely inhibited, dwarfed, an...
