The invention relates to an application technology of quinclorac in corn fields, by which the quinclorac is processed into conventional pesticide formulations, i.e. suspending agents, wettable powder, soluble powder, water-dispersible granules, and the like through a modern pesticide formulation processing technology and is used for preventing and killing common barnyard grass, crab grass, green bristlegrass, and the like in the corn fields. The invention prevents and kills objects of the barnyard grass, the crab grass, the green bristlegrass, and the like in the corn fields and has the effective component usage amount of 300-900 gai / hm<2> according to grass ages and weeds density, and the quinclorac is blended with 30-40 kilograms of water per mu for uniform mist spraying during a corn 1-leaf period and a weed 1-5 leaf period.
Description
technical field [0001] The invention belongs to the application technology of herbicides, and in particular relates to the use and application technology of quinclorac in corn fields. Background technique [0002] The chemical name of the compound quinclorac is 3-7-dichloro-8-quinolinecarboxylic acid. [0003] Its structural formula is: [0004] [0005] Quinclorac, English common name quinclorac. It is developed by BASF Corporation of Germany and has obtained patent EP 60429 (1983); US 4497651 (1985); 4632696 (1987); DE 3108873 (19820; 32027736 (1983). Spain and South Korea introduced quinclorac from BASF Corporation in 1989 The production technology of quinclorac was carried out by Shenyang Research Institute of Chemical Industry for the first time in China. At present, many domestic manufacturers are producing quinclorac. [0006] Quinclorac is a quinoline carboxylic herbicide similar to hormones. The agent can be quickly absorbed by germinated seeds, roots, stems a...
