Problems solved by technology

[0005] At present, herbicides in paddy fields are limited by the safety of crops, and the herbicidal spectrum is also limited. Using a single herbicide alone cannot completely and effectively control the occurrence of weeds in paddy fields. Uniformity is also likely to cause residual toxicity to current crops or subsequent crops

Abstract

The invention belongs to the field of the pesticide, relating to a hybrid weeding composite containing Bispyribac-sodium and oxaziclomefone. The hybrid weeding composite takes the Bispyribac-sodium and the oxaziclomefone as main effective ingredients with the mass ratio of (1-99):(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. The weeding composite can be used for preventing and removing paddy field grass family weeds, broad leaf weeds and cyperaceae weeds. On the premise of improving pesticide effect, the weeding composite can delay weed resistance, has the advantages of wide weeding spectrum and long effect lasting period if being compared with a single agent, 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 field of pesticides, in particular to the field of herbicides, and relates to a mixed herbicidal composition containing bispyribac and oxaziculone. The herbicidal composition can be used for post-emergence weeding in paddy fields. 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] Oxazimidone, also known as debainan, chemical name: 3-[1-(3,5-dichlorophenyl)-1-methylethyl]-2,3-dihydro-6-methyl- 5-Phenyl-4H-1,3-oxazin-4-one. This herbicide is a new type of oxazinone herbicide. It...
