Embodiment 1

[0083] 40% active compound (35.0% 2-mercaptobenzothiazole zinc and 5.0% pyraclostrobin composition), fatty alcohol polyoxyethylene ether 2.0%, maleic acid-acrylic acid homopolymer sodium salt 3.0%, yellow Raw gum 0.05%, magnesium aluminum silicate 0.6%, sodium starch octenyl succinate 1.0%, glycerol 2.0%, phenyl salicylate 0.4%, silicone defoamer 0.1%, deionized water to 100 %, put it into a high-shear homogeneous emulsifier and shear it at high speed for 20 minutes, then transfer it to a sand mill, and circulate sand mill for 1-3 times to obtain a 40% content active compound suspending agent.

Embodiment 2

[0085] 30% active compound (20.0% 2-mercaptobenzothiazole zinc and 10.0% azoxystrobin combination), fatty alcohol polyoxyethylene ether sulfate 1.0%, phenolsulfonic acid condensate sodium salt 1.0%, polymer polycarboxylate Salt 2.0%, sodium starch octenyl succinate 2.0%, glycerol 2.0%, silicone defoamer 0.1%, Cathone 0.2%, deionized water to 100%, put into high-shear homogeneous emulsification High-speed shearing in the machine for 25 minutes, then pumped into a sand mill for 90 minutes of sand grinding, and filtered to obtain a 35% active compound suspension.

[0086] 2. Microcapsule suspension

Embodiment 3

[0088] 25% active compound (10.0% 2-mercaptobenzothiazole zinc and 15.0% trifloxystrobin composition) microcapsule suspension preparation method: 10.0% 2-mercaptobenzothiazole zinc, 15.0% trifloxystrobin, alkylnaphthalene Sulfonate 1.0%, acyl glutamate 2.0%, silicone defoamer 0.1%, polyphenyl polymethylene polyisocyanate PAPI 3% and diphenylmethane diisocyanate MDI 2%, gum arabic (5% 10% aqueous solution and 40.46% deionized water are fully mixed, and then put into a sand mill for sand grinding until the D90 particle size is 3-5 microns. Start stirring (maintain 700 rpm), then raise the temperature of the sand-milled suspension to 60°C, and slowly add 0.04% triethanolamine at the same time to maintain a stable solidification temperature of the capsule wall material for 8 hours, then add fatty alcohol polyoxyethylene ether Sulfate 1.0%, sodium methylnaphthalenesulfonate formaldehyde condensate 1.0%, urea 2.0%, glycerol 2.0%, aluminum magnesium silicate (2%) aqueous solution 10%...

Abstract

The present invention relates to a composition of bactericidal active compounds, and in particular to a composition comprising zinc 2-mercaptobenzothiazole and a mitochondrial cytochrome enzyme inhibitor (QoIs) bactericide and its formulation and use. A bactericidal composition comprising a bactericidal active compound I and a bactericidal active compound II. The bactericidal active compound I is zinc 2-mercaptobenzothiazole, and the bactericidal active compound II is at least one selected from mitochondrial cytochrome bactericides. Azoxystrobin, tristrostrobin, trifloxystrobin, pyraclostrobin, tristrostrobin, pyraclostrobin, tristrostrobin and cyanostrobin. The fungicidal active compound composition of the present invention can effectively slow down the development of drug resistance of diseases and greatly reduce the risk of resistance caused by the separate use of QoIs fungicide and 2-mercaptobenzothiazole zinc; the invention can also give full play to the QoIs fungicide and 2-mercaptobenzothiazole zinc Benzothiazole zinc has a preventive and therapeutic effect on fungal, bacterial and other diseases, as well as its good protective properties.

Description

Technical field [0001] The invention belongs to the field of agriculture and relates to a bactericidal active compound composition, and in particular to a composition containing zinc 2-mercaptobenzothiazole and a mitochondrial cytochrome enzyme inhibitor bactericide, as well as its preparation and application. Background technique [0002] 2-Mercaptobenzothiazole salt is mainly used as a rubber vulcanization accelerator. The US patent (US004012332) discloses a rubber vulcanization agent containing copper 2-mercaptobenzothiazole. The Chinese patent (CN101463018A) discloses a rubber vulcanization agent based on 2-mercapto group. A method for preparing rubber vulcanization accelerator dibenzothiazole disulfide using sodium benzothiazole as raw material. In addition to being widely used in the field of rubber vulcanization, 2-mercaptobenzothiazole salts can also be used as agricultural fungicides. Chinese patent (CN101514210B) discloses a copper-2-mercaptobenzothiazole with a sp...
