Abstract

The invention discloses a weeding composition containing Quinclorac, a preparation method and an application thereof. The composition comprises a compound (A) and a compound (B), wherein the compound (A) is the Quinclorac and the compound (B) is atrazine. The weeding composition can be prepared into general formulations of pesticide such as suspending agents, wettable powder, water dispersible granula and the like after being mixed according to a suitable proportion by modern pesticide preparation process technology, and is used for preventing and extirpating weeds such as cockspur grass, hairy finger, green bristlegrass, acalypha australis, piemarker, purslane, Amaranthus retroflexus and the like. The preventing effect is obviously better than the preventing effect when the compound (A) or the compound (B) is used respectively; and the invention greatly reduces the using dosage of each of the active material, and not only has ecological significance but also has important environmental protection significance.

Description

technical field [0001] The invention relates to an improved herbicidal composition, in particular to a herbicidal composition containing quinclorac and atrazine and its application. Background technique [0002] The general name of compound (A) is quinclorac, and its chemical name 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 first researched and developed by Shenyang Research Institute of Chemical Industry in China. [0006] Quinclorac is a quinoline carboxylic herbicide similar to hormones. The agent can be quickly absorbed by germinated seeds, roots, stems and leaves, and quickly conduct to the stems...
