Problems solved by technology

[0007] 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 pesticides, and relates to a mixed herbicide composition containing bispyribac-sodium and quinclorac. The herbicide composition adopts the bispyribac-sodium and the quinclorac as main active components, the weight ratio of the bispyribac-sodium and the quinclorac is 1 to 99:1 to 99, and different surfactants, thickening agents, solvents, solid fillers or the like can be added to the herbicide composition to become a variety of agents, such as emulsifiable concentrate, suspending agents, water-dispersible granules, wettable powder and the like. The herbicide composition can prevent and get rid of annual gramineous weeds, broadleaf weeds and cyperaceous weeds in paddy fields, and compared with single agents, the herbicide composition delays the resistance of weeds under the premise that the pesticide effect is enhanced, has a broad weeding spectrum and long persistence, is safe for rice and next-stubble crops, and therefore 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 quinclorac. 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] Quinclorac, also known as quick killing barnyard, killing barnyard net, gram barnyard star. Chemical name: 3,7-dichloro-8-quinolinecarboxylic acid, structural formula: [0005] [0006] The herbicid...
