Abstract

The invention relates to an ethylenediamine copper bactericide composition and a preparation method. The ethylenediamine copper chelate compound is composed of ethylenediamine and copper ions which have a bactericidal function and is used as the main body of the bactericide. , inorganic fungicide compound, and other additives, plant growth regulators to form a high-efficiency fungicide. The bactericidal compound has a very low concentration of free copper ions and a wide antibacterial spectrum, and has good effects in preventing and controlling crop blight, powdery mildew, early blight and the like (endogenous and soil-borne plant diseases). The production process is simple, the raw materials are easy to obtain, the production cost is low, and the production is easy to popularize.

Description

technical field [0001] The invention mainly relates to a copper fungicide, in particular to a copper fungicide with systemic action. Background technique [0002] Copper fungicides have been widely used in agriculture. Wherein the very common method of application is: adopt divalent copper and the compound method that has complexing and chelation to form copper complex, to reduce the concentration of free divalent copper ion, reduce the phytotoxicity of copper ion. Such compounds as copper ammonia, copper amino acid, copper succinate, copper glutarate, copper citrate, copper ethylenediaminetetraacetate, copper hydroxyethylethylenediaminetriacetate, copper ethylenediaminetetramethyl Copper phosphate, etc., have been used in agriculture to prevent and control a variety of pathogens in crops. From the perspective of copper ion complexation and chelation, these compounds have not reached the maximum level of chelation or complexation of copper ions, and the free Cu 2 The conc...
