preparation Embodiment 1

[0064] Dosage Form Preparation Example 1 The dosage form preparation embodiment of zinc thiazole and organocopper fungicide copper quinolate

[0065] Example 1-1: 40% zinc thiazole·copper quinolate (35.0%+5.0%) suspension concentrate

[0066] 35g thiazole zinc, 5g quinoline copper, 2.5g fatty alcohol polyoxyethylene ether, 2.5g alkylnaphthalene sulfonate, 1.01g methylnaphthalenesulfonate sodium formaldehyde condensate, 0.1g gum arabic, 0.7g aluminum silicate Magnesium, 2.54g glycerol, 0.6g sodium benzoate, 0.1g organic silicon defoamer, deionized water to make up to 100g, put it into a high-shear homogeneous emulsifier and shear at high speed for 20 minutes, and then transport it to a sand mill , circulate sanding 3 times to obtain the suspending agent.

Embodiment 1-2

[0067] Embodiment 1-2: 50% zinc thiazole·copper quinolate (10.0%+40.0%) suspension concentrate

[0068] 10g thiazole zinc, 40g quinoline copper, 1.5g tallow ethoxyamine salt, 2.0g acyl glutamic acid salt, 3.0g dioctyl sulfosuccinic acid sodium salt, 3.0g urea, 0.1g polyether defoaming Agent, deionized water to make up to 100g, put into a high-shear homogeneous emulsifier and shear at high speed for 20 minutes, and then use a high-pressure homogenizer to homogenize to obtain a 50% suspending agent.

Embodiment 1-3

[0069] Embodiment 1-3: 25% zinc thiazole·copper quinolate (10.0%+15.0%) microcapsule suspension

[0070] 10g thiazole zinc, 15g quinoline copper, 2.0g EO / PO block polyether, 1.0g phenolsulfonic acid condensate sodium salt, 0.16g silicone defoamer, 3.4g polyphenyl polymethylene polyisocyanate PAPI , 2.0g diphenylmethane diisocyanate MDI, 10.0g gum arabic aqueous solution (the mass fraction of gum arabic is 5%) and 39.0g deionized water are fully mixed, and then put into a sand mill for sand grinding until D90 grains 4 microns in diameter. Then start stirring (maintain at 700 rpm), and raise the temperature of the sand-milled suspension to 60°C. At the same time, slowly add 0.04g of triethanolamine to maintain a stable solidification temperature of the capsule wall material for 8 hours, and then add 2.0g of fatty alcohol polysaccharide Oxyethylene ether sulfate, 1.1g polymer polycarboxylate, 2.2g urea, 2.2g glycerin, 9.5g sodium carboxymethyl cellulose aqueous solution (its mas...

Abstract

The invention discloses an application and preparation of a composition containing zinc thiazole and an organic copper fungicide. The composition is consist of the zinc thiazole and the organic copperfungicide, wherein the weight ratio of the zinc thiazole to the organic copper fungicide is 1:0.01-100). When the active ingredients of the zinc thiazole and the organic copper fungicide in the composition exist in a specific weight ratio, the bactericidal activity is greater than the total bactericidal activity of the zinc thiazole and the organic copper fungicide, and significant synergistic effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to a composition containing thiazole zinc and organic copper bactericides and its preparation and application, more specifically, to a composition containing thiazole zinc and copper quinoline, copper ammonia, copper nonylium, mixed amino acids Compositions of one or more of copper and copper acetate, formulations and uses thereof. Background technique [0002] Zinc thiazole is a thiadiazole organozinc fungicide, which is a compound (ZL00132119.6) successfully developed by the applicant in 1999. Its single agent has entered the market in large quantities to serve agriculture. Zinc thiazole has an outstanding control effect on plant bacterial diseases, and also has a good control effect on some fungal diseases. At the same time, when the concentration is appropriate, it can promote the growth of plant roots and stems and leaves, and improve stress resistance and disease resistance...
