Problems solved by technology

[0012] The application of quinclorac in paddy fields is relatively popular, but for the application in rapeseed fields, especially the mixed use of domestic and foreign patents with metazachlor in rapeseed fields has not been mentioned; therefore the combination of quinclorac and metazachlor The mixing effect is unpredictable

Embodiment 1

[0024] Embodiment 1 is a dosage form preparation example, and embodiment 2 is a biological embodiment,

[0025] Example 1:

[0026] a Wettable powder: 60 parts by weight of active ingredient composition and 2 parts by weight of sodium dodecylbenzenesulfonate used as wetting agent, 2 parts by weight of JFC used as wetting agent, 10 parts by weight of Granular white carbon black is used as an adsorbent, 10 parts by weight of sodium lignosulfonate used as a dispersant and 16 parts by weight of kaolin are ultrafinely pulverized in a jet mill to obtain a wettable powder.

[0027] B water dispersible granules: 45 parts of weight of active ingredient (A), 35 parts of weight of active ingredient (B), 10 parts of weight of carboxylate used as wetting and dispersing, 5 parts of weight of carboxylate used as dispersant Sodium lignosulfonate and 5 parts by weight of kaolin are superfinely pulverized in an airflow mill, and then an appropriate amount of water is added for stirring and gra...

Embodiment 2

[0030] Example 2, the control effect of quinclorac and metazachlor mixed with weeds in rapeseed field

[0031] Location: Jiangsu, Xinyi

[0032] Application period: 2-3 leaf stage of weeds Survey: 30 days after application Time: 2008

[0033]

[0034] Conclusion: The actual control effect of the mixed use of quinclorac and metazachlor is higher than the expected theoretical control effect of the mixed use.

[0035] It can expand the herbicidal spectrum, which proves that the combination of quinclorac and metazachlor has synergistic effect and can expand the herbicidal spectrum.

Abstract

The invention provides to a herbicidal composition containing quinclorac and metazachlor and a preparation method and application. The composition is the mixture of the compound (A) quinclorac and the compound (B) metazachlor. The composition is characterized in that the weight ratio of quinclorac to metazachlor is 1-50:1-50; and after quinclorac and metazachlor are mixed according to appropriate proportion, the mixture of quinclorac and metazachlor 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 the annual grass weeds and such broadleaf weeds in the rape fields as amaranth, chamomile, matricary, knotweeds, mustard, eggplants, chickweeds, catchweeds, cocklebur, amaranth ragweeds, smartweeds, Malachium aquaticum(L.) Fries, speedwell and the like. 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 performance, in particular to a herbicidal composition containing quinclorac and metazachlor. 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 ...
