Noncorrosive cuprammonia fungicide and method for using same

摘要

A substantially noncorrosive solution of cuprammonia low carboxylate complex of copper carboxylate and ammonium carboxylate is described wherein said complex is fungicidally and bactericidally effective when diluted with water in an amount of 3 to 200 parts of water per part of complex solution. The dilution effects the hydrolysis of the complex to precipitate in finely divided flocculent form fungicidally and bactericidally active copper values. When the flocculent precipitate is applied to the locus of bacteria or vegetation on which fungus is to be controlled, the flocculent precipitate forms a gelatinous coating of copper values which adhere tenaciously to the locus of application or vegetation where applied. Once dried, the coating adheres as a coating which is not readily removed by moisture or rainfall.
