Abstract

The invention discloses mesophilous bacterial chlorin water dispersion granule agent in disinfectant, and belongs to the disinfectant technology in the plant protection field. The invention comprises the components that the raw material medicine mesophilous bacterial chlorin occupies 100 to 600 shares, auxiliary agent occupies 180 to 360 shares, carrier packing material occupies 250 to 600 shares, and binding agent occupies 10 to 150 shares. The ingredients are mixed proportionally, after being evenly mixed, the mixture is crushed to obtain the target powder, the target powder and the binding agent are evenly mixed, and the mesophilous bacterial chlorin water dispersion granule can be obtained through granulation, drying and screening. The invention overcomes the disadvantage of the wettable powder of the mesophilous bacterial chlorin, both the us-cost of the farmer and the environment pollution are reduced. The invention has the advantages that the content is high, the disintegration is quick, the dispersivity is good, the invention is advantageous for storage and transportation and the stability is good, the activeness is high, the efficiency is good, and the invention is secure.

Description

technical field [0001] The invention relates to an agricultural fungicide, in particular to a Zhongshengmycin water-dispersible granule which has dual functions of protecting and treating crops, and also relates to a preparation method of the agricultural fungicide. Background technique [0002] At present, there are many agricultural fungicides, and Zhongshengmycin is one of them. It belongs to N-glycoside antibiotics. It has a wide antibacterial spectrum and can resist Gram-positive and negative bacteria, mycobacteria, yeast and filamentous fungi. . In particular, it has obvious antibacterial activity against pathogenic bacteria of crops such as rice bacterial blight, apple ring spot, citrus canker, and watermelon wilt. Zhongshengmycin not only has a therapeutic effect but also a protective effect. It is mainly used to prevent and control bacterial diseases of crops. It has good safety, wide bactericidal spectrum and outstanding effect. The current situation that ketone ...
