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.La présente invention appartient au domaine technique des fongicides agricoles. La présente invention concerne le complexe de manganèse et de zinc de 2-mercaptobenzothiazole, le procédé de préparation de celui-ci et lapplication de celui-ci. La structure chimique du complexe de manganèse et de zinc de 2-mercaptobenzothiazole est décrite sous la forme de la formule ci-dessus, dans laquelle m, n et n sont des nombres entiers positifs, m = 2(n+n), n ≥ n et n:n = 1:1-9:1. Les matériaux sont pesés en fonction du rapport stœchiométrique des produits cibles. Le 2-mercaptobenzothiazole est dissous dans une solution dhydroxyde de sodium. La solution aqueuse de sels de manganèse solubles dans leau et la solution de sels
