Abstract

The invention belongs to the technical field of pesticide, and discloses a dithianon water-dispersible granule. The granule comprises the following components in percentage by mass: 20 to 80 percent of dithianon, 3 to 12 percent of wetting agent, 3 to 12 percent of dispersant, 2 to 10 percent of disintegrant, 0.1 to 5 percent of binder and 5 to 72 percent of filler. The components are mixed pro rata, stirred well and then ground so as to give mother powder; the mother powder is well mixed with the binder; and then the mixture is granulated, dried and sieved so as to prepare the dithianon water-dispersible granule. The granule has the advantages of overcoming the disadvantages of suspending agents and wettable powder and reducing pollution on environment, and is mainly used for controlling fruit-tree scab, leaf spot, alternaria leaf spot, vegetable anthracnose and downy mildew.

Description

Technical field: [0001] The invention belongs to the technical field of pesticides, and in particular relates to a water-dispersible granule of dicyanoanthraquinone used for preventing and treating fruit tree scab, leaf spot, spot defoliation, vegetable anthracnose and downy mildew. Background technique: [0002] Dicyanoanthraquinone (dithianon) is a fungicide developed by BASF Europe, and its pure product is a dark brown crystalline solid. Molecular formula is C 14 h 4 N 2 o 2 S 2 , the chemical name is: 2,3-dicyano-1,4-dithioanthraquinone, and the structural formula is: [0003] [0004] Dicyanoanthraquinone has multiple action mechanisms. It inhibits a series of fungi and molds by reacting with sulfur-containing groups and interfering with cell respiration, and finally leads to the death of diseases. It has good protective activity and certain therapeutic activity. For the control of all fruit tree diseases such as scab, mildew, leaf spot, rust, anthracnose, down...
