Embodiment 1-1A

[0163] Example 1-1A Compound thiazole manganese zinc [C 4 H 4 N 6 S 4 (Mn) 0.5 (Zn) 0.5 ] Preparation

[0164] At room temperature, add 7.99g of 2-amino-5-mercapto-1,3,4-thiadiazole (0.06mol) to a 250ml flask, add 30ml of water, stir, and add a solution of 2.45g of sodium hydroxide dissolved in an appropriate amount of water , Stir to dissolve, and then add 2.535g of manganese sulfate monohydrate (0.015mol) and 4.314g of zinc sulfate heptahydrate (0.015mol) in a mixed solution of appropriate amount of water. A large amount of precipitation will precipitate. Stir at 30-40°C for half an hour. Take out and cool, filter with suction, wash the solid with a small amount of water until the filtrate has no sulfate ions, and filter with suction. The obtained solid is diluted and dried at about 100°C in vacuum for about 5 hours to obtain 7.1g of brown-gray solid; melting point is greater than 290°C; infrared spectrum (ν KBr max cm -1 ) 3372.4, 3272.1, 3174.6, 2938.3, 2848.2, 2722.8, 1612....

Embodiment 1-2A

[0165] Example 1-2A Compound mancozeb thiazole [C 4 H 4 N 6 S 4 (Mn) 0.5 (Zn) 0.5 ] Hydrate Preparation

[0166] At room temperature, add 7.99g of 2-amino-5-mercapto-1,3,4-thiadiazole (0.06mol) to a 250ml flask, add 30ml of water, stir, and add a solution of 2.45g of sodium hydroxide dissolved in an appropriate amount of water , Stir to dissolve, then add 2.535g of manganese sulfate monohydrate (0.015mol) and 4.314g of zinc sulfate heptahydrate (0.015mol) dissolved in a proper amount of water, stir at about 30℃ for half an hour, take it out and let it cool and filter with suction Wash the solid with a small amount of water until the filtrate is free of sulfate ions, and filter with suction. The obtained solid is diluted and dried at about 50℃ for about 4 hours to obtain 7.5g of brown-gray solid; the water content is 6.62% by the Karfel method; thermal analysis: weight loss is about 6.82% (See attached figure 1 ), has a corresponding endothermic peak (DTA) under weightlessness (se...

Abstract

The invention relates to a broad-spectrum bactericidal pollution-free growth-promoting thiazole manganese-zinc compound. According to the invention, compared to single preparations, the broad-spectrumbactericidal pollution-free growth-promoting thiazole manganese-zinc compound can simultaneously achieve effects of sterilization and manganese and zinc supplementation when being applied to crops; and compared to compounding, the broad-spectrum bactericidal pollution-free growth-promoting thiazole manganese-zinc compound has characteristics of accurate preparation content, cumbersome formulationprocess reducing, convenient application, easy preparation, low energy consumption, environmental protection, good storage stability or prevention and treatment effect and the like, and is suitable for preparing compositions containing the compound, pesticides for preventing and treating various bacterial and fungal diseases on crops and / or promoting crop health or growth and development, or medicaments in the fields of protecting industrial materials from being invaded by bacteria and the like.

Description

Technical field [0001] The invention relates to the technical field of pesticides, in particular to provide a new compound with better stability of broad-spectrum bactericidal manganese thiazole and its agricultural composition, and a preparation method and application thereof. Background technique [0002] Zinc thiazole, chemical name is bis(2-amino-5-mercapto-1,3,4-thiadiazole) zinc, CAS: 1202750-31-9, molecular formula, C 4 H 4 N 6 S 4 Zn, with a molecular weight of 329.77, can be used in the field of fine chemicals including photosensitivity or material science. It is also an organozinc broad-spectrum fungicide developed by Zhejiang Xinnong Chemical Co., Ltd. The drug has multiple effects such as systemic, conduction, prevention, protection, and treatment, and its therapeutic effect is greater than its protective effect. It is a new generation of high-efficiency, low-toxicity, and broad-spectrum fungicide for preventing and controlling bacterial diseases of crops. Both bacter...
