Abstract

The invention relates to a copper ethylenediamine bactericide composition and a preparation method thereof. Ethylenediamine with bactericidal function self and copper ions are selected for forming copper ethylenediamine chelate, and the copper ethylenediamine chelate is taken as a main body of the bactericide, compounded with other cupreous organic and inorganic bactericides and combined with other auxiliaries and a plant growth regulator, so as to form an efficient bactericide. The copper ethylenediamine bactericide composition has the advantages that concentration of free copper ions is extremely low, the antibacterial spectrum is broad, and the effect of preventing and treating wilt, powdery mildew, early blight and the like (endogenous and soil borne plant diseases) of crops is good; the production technology is simple, raw materials are available, and the production cost is lower, so that the copper ethylenediamine bactericide composition 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...
