Abstract

The invention relates to a composite germicide, which simultaneously comprises three components, namely azoxystrobin, difenoconazole and cyproconazole. The germicide is prepared from the following active ingredients in percentage by weight: 1 to 40 percent of azoxystrobin, 1 to 30 percent of difenoconazole, 1 to 40 percent of cyproconazole, a wetting agent, a dispersant, an emulsifying agent, a thickening agent, a stabilizer, an antifreezing agent, an antifoaming agent and a solid carrier or a solvent. The composite germicide has effects and use which are obviously superior to those of germicides comprising one or two components.

Description

technical field [0001] The present invention relates to a mixed fungicide, especially a three-component compound of a methoxyacrylate fungicide: azoxystrobin and a class of triazole fungicides: cyproconazole and difenoconazole The bactericide belongs to the technical field of compound pesticides. Background technique [0002] Azoxystrobin (common English name azoxystrobin) is named Amixida and Amida, with 25%, 80% water dispersible granules, 22.9% suspending agent, etc. It is used for cereal crops, rice, peanuts, grapes, Fruit trees control powdery mildew, rust, downy mildew, rice blast, etc. [0003] The trade names of difenoconazole (English common name difenoconazole) are difenoconazole, difenoconazole, and Shigao. Preparation products include 3% suspension seed coating and 10% water dispersible granules. It is mainly used to control pear scab, apple leaf spot, tomato early blight, western claw blight and so on. [0004] The main preparations of cyproconazole (English...
