Abrégé

The present invention belongs to the technical field of agricultural fungicides. Disclosed are 2-mercaptobenzothiazole manganese zinc, preparation method therefor and application thereof. The chemical structure of 2-mercaptobenzothiazole manganese zinc is showed as the above formula, wherein m, n and n' are a positive whole number, m = 2(n+n'), n≥n', and n: n' = 1:1-9:1. Weighed are materials according to the stoichiometric ratio of target products. 2-mercaptobenzothiazole is dissolved in sodium hydroxide solution. The aqueous solution of water-soluble manganese salts and water-soluble zinc salts solution are successively added to 2-mercaptobenzothiazole sodium solution under stirring, standing, filtering and washing with water to obtain cake, and then vacuum drying it to obtain 2-mercaptobenzothiazole manganese zinc. The present 2-mercaptobenzothiazole manganese zinc may be used as an agricultural fungicide. On the surface of solid particles presents 2-mercaptobenzothiazole manganese complex with zinc to form a stable complex of 2-mercaptobenzothiazole manganese zinc. Tests show that the complex has excellent effect for controlling a plurality of diseases including an apple alternaria leaf spot, a pear scab, an apple ring rot and an apple anthracnose and the like.
