Embodiment 1

[0036] 20% active ingredient (A) with 5% active ingredient (B), 2% sodium lauryl sulfate as wetting agent, 4% NNO as dispersant, 6% lignin as dispersant Calcium sulfonate and other inert fillers are thoroughly mixed together and ultrafinely pulverized to obtain a wettable powder.

Embodiment 2

[0038] 50% active ingredient (A) with 10% active ingredient (B), 2% carboxylate as wetting agent, 4% NNO as dispersant, 6% lignosulfonic acid as dispersant Calcium and other inert fillers are thoroughly mixed together and ultrafinely pulverized, and then an appropriate amount of water and a binder is added to the mixture, and the water-dispersible granules can be obtained after fluidized bed granulation or extrusion granulation and drying.

[0039] Biological example:

[0040] Example 1:

[0041] The control effect of quinclorac and nicosulfuron on weeds in cornfield is shown in the table

[0042] Location: Xinyi, Jiangsu Province Investigation period: 20 days after taking the medicine Time: 2009

[0043]

[0044] Conclusion: The actual control effect of the combination of quinclorac and nicosulfuron is greater than the theoretical control effect, indicating that the combination of quinclorac and nicosulfuron has a synergistic effect.

Abstract

The invention discloses a novel quinclorac composition, a preparation method thereof and application thereof. The novel quinclorac composition may be a group of compounds (B) consisting of a compound A quinclorac and at least one selected from one of nicosulfuron, formamidosulfuron and rimsulfuron. The weeding composition of the invention can be processed into conventional pesticide preparations such as wettable powder and water dispersible granules, which are used for preventing and eliminating weeds such as cockspur grass, crab grass, green bristle grass, acalypha australis, piemarker, purslane and amaranthus retroflexus growing in corn fields, by mixing in a proper ratio and by modern pesticide preparation processing technology. The prevention effect is obvious better than the effect that the compound (A) or the compound (B) is used alone and the dosage of each active ingredient is greatly reduced. The novel quinclorac composition has an ecological significance and an important environment-protection significance.

Description

technical field [0001] The present invention relates to an improved herbicidal composition, in particular to a herbicidal composition containing quinclorac, nicosulfuron, rimsulfuron-methyl, rimsulfuron-methyl and its use. 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...
