Abstract

A kasugamycin and copper chloride wettable powder consists of the following ingredients in percentage by weight: 45% of copper chloride, 2% of kasugamycin, 2% of dispersing agent NNO, 4% of K12 and the balance of white carbon black. The preparation process comprises the steps of: (1) uniformly mixing copper chloride, the kasugamycin, the dispersing agent NNO, the K12 and the white carbon black in a ratio; (2) carrying out ultrafine grinding on the mixture by using a jet mill so as to obtain the original powder; (3) uniformly mixing the original powder which is obtained after ultrafine grinding with a binding agent according to the formula; (4) granulating the mixture through a granulator; (5) drying granules; and (6) screening dried granules so as to obtain the kasugamycin and copper chloride wettable powder.

Description

technical field [0001] The invention relates to an agricultural fungicide, in particular to a kasugamycin king copper wettable powder which has dual functions of prevention and treatment for crops, and also relates to a preparation method of the agricultural fungicide. Background technique [0002] At present, there are many agricultural fungicides, and King Copper is one of them. After being sprayed on the crops, King Copper can adhere to the surface of the plants, forming a protective film, which is not easy to be washed away by rain. Under certain humidity conditions, it releases soluble basic copper chloride ions to play a bactericidal effect. It is mainly used to prevent and treat citrus canker, and can also be used to prevent and control other fungal diseases and some bacterial diseases. The technical characteristics of this product are wide bactericidal spectrum, high curative effect, no resistance, no pollution to the environment, and obvious passivation and control...
