Abstract

The invention relates to a sterilization composition which contains the following effective ingredients in percentage by weight: 10-80% of dithianon and 70-1% of tebuconazole. Dispersing agent, wetting agent, disintegrating agent, cementing agent, thickening agent, anti-freeze agent, anti-foaming agent, and filling or deionized water are added to the composition to prepare water dispersible granules, wetting powder and suspending agent. The invention not only enlarges the anti-fungal spectrum of each effective ingredient, but also improves the biological activity of the effective ingredients. Experiments prove that the sterilization composition has better preventing and curing effects on diseases of various fruit trees and vegetables. The sterilization composition is especially suitable for preventing and curing alternaria leaf spot, leafspot, cladosporium cucumerinum and downy mildew, has no chemical injury to crops and has small pollution to environment.

Description

Technical field: [0001] The invention belongs to the technical field of pesticides, and relates to the application of a fungicide compounded with dicyanoanthraquinone and tebuconazole to diseases of fruit trees and vegetables. technical background: [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. Used to control all fruit tree diseases such as scab, mildew, leaf spot, rust, anthracnose, downy mildew, brown rot, etc. [0005] Tebuconazole (tebuconazo...
