2-Mercaptobenzothiazole manganese zinc, preparation method therefor and application thereof
The present invention belongs to the technical field of agricultural fungicides and discloses a 2-mercaptobenzothiazole manganese zinc, preparation method therefor and application thereof. The chemical structure of the 2-mercaptobenzothiazole manganese zinc is shown as the above formula. Wherein m, n and n′ are positive integers, m=2(n+n′), n≧n′, n:n′=1:1˜9:1. Materials are prepared according to the stoichiometric ratio of the 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, followed by stirring for mixing well, then the solution being allowed to stand, filtered and washed with water to obtain filter cake, and then dried in vacuum to obtain 2-mercaptobenzothiazole manganese zinc. The present 2-mercaptobenzothiazole manganese zinc may be used as an agricultural fungicide. The present invention coordinates the surface of solid particles of 2-mercaptobenzothiazole manganese with zinc to form a stable clathrate of 2-mercaptobenzothiazole manganese and zinc. Tests show that the clathrate has excellent effect for controlling a plurality of diseases including apple alternaria leaf spot, pear scab, apple ring rot, apple anthracnose and the like.
