Embodiment 1

[0023] Embodiment 1 is a dosage form preparation example, and embodiment 2 is a biological embodiment,

[0024] Example 1:

[0025] a wettable powder: 50 parts by weight of active ingredient composition and 2 parts by weight of sodium dodecylbenzenesulfonate as wetting agent, 5 parts by weight of granular white carbon black as adsorbent, 10 parts by weight Sodium lignosulfonate used as a dispersant and 33 parts by weight of kaolin were ultrafinely pulverized in a jet mill to obtain a wettable powder.

[0026] B water dispersible granules: 40 parts of weight of active ingredient (A), 30 parts of weight of active ingredient (B), 10 parts of weight of carboxylate used as wetting and dispersing, 10 parts of weight of carboxylate used as dispersant Sodium lignosulfonate and 10 parts by weight of kaolin are superfinely pulverized in an airflow mill, then added with appropriate amount of water for stirring and granulation, or granulated by a fluidized bed and then dried to obtain a ...

Embodiment 2

[0029] Embodiment 2, the control effect of quinclorac and grass-cutting mixed with weeds in rapeseed field

[0030] Location: Jiangsu, Xinyi

[0031] Application period: 2-3 leaf stage of weeds Survey: 30 days after application Time: 2008

[0032]

[0033] Conclusion: The actual control effect of quinclorac and quinclorac is higher than the expected theoretical control effect of its mixed use, and it can expand the spectrum of weed control. .

Abstract

The invention provides to a herbicidal composition containing quinclorac and benazolin and a preparation method and application. The composition is the mixture of the compound (A) quinclorac and the compound (B) benazolin. The composition is characterized in that the weight ratio of quinclorac to benazolin is 1-50:1-50; and after quinclorac and benazolin are mixed according to appropriate proportion, the mixture of quinclorac and benazolin can be processed into wettable powder, water-dispersible granules, suspending agents and other conventional formulations of pesticide through the modern pesticide preparation processing technology. The herbicidal composition can effectively prevent and kill off such annual grass weeds as crabgrass, millets, bluegrass, bristlegrass and the like and such broadleaf weeds as amaranth, chamomile, matricary, knotweeds, mustard, eggplants, chickweeds, catchweeds, cocklebur, amaranth ragweeds, smartweeds, Malachium aquaticum(L.) Fries, speedwell and the like in the rape fields. The control effect of the composition is obviously better than that of the single compound (A) or compound (B), thus substantially reducing the application dosage of various active substances.

Description

Technical field: [0001] The present invention relates to a herbicidal composition with improved properties, in particular to a herbicidal composition containing quinclorac and quinclorac. 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 th...
