Abstract

The invention belongs to the technical field of the pesticide, in particular to the field of the herbicide. The invention discloses a hybrid weeding composite containing Bispyribac-sodium and fluroxypyr. The weeding composite takes Bispyribac-sodium and fluroxypyr as the main effective ingredients with the mass ratio of (0.1-99):(0.1-99). In the weeding composite disclosed by the invention, different surfactants, thickeners, solvents or solid fillers and the like can be added to be processed into various dosage forms, such as missible oil, a suspending agent, water dispersible granules, wettable powder and the like. On the premise of improving pesticide effect, the weeding composite can delay weed resistance and has the advantages of wide weeding spectrum and long effect lasting period if being compared with a single agent; paddy field grass family weeds and broad leaf weeds can be prevented and removed; and the hybrid weeding composite is safe to the paddy and next batch of crop and is an ideal paddy field herbicide.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to the field of herbicides, and relates to a mixed herbicidal composition containing bispyribac and fluroxypyr and its application. The herbicidal composition has a remarkable effect of weeding after the rice field is applied. Background technique [0002] Bispyribac, also known as Nongmeili, bispyrimidine salicylate, chemical name: 2,6-bis(4,6-dimethoxypyrimidinyl-2-oxyl)sodium benzoate. It is a phenoxycarboxylic acid herbicide, which mainly inhibits the synthesis of acetic acid through roots and leaves and hinders the biosynthesis of branched chain amino acids. It is a selective herbicide and is used in direct-seeding rice fields with a wide weeding spectrum. Its structural formula is as follows: [0003] [0004] Clofluroxy acetic acid, also known as making it long. Chemical name: 4-amino-3.5-dichloro-6-fluoro-pyridine-2-oxyacetic acid, structural formula: [0005] ...
