Fixed Copper is a term that refers to several relatively insoluble forms of copper that are safer for fruit crops than basic copper sulfate and more convenient to use than Bordeaux mixture. The fixed copper compounds are sold under many trade names but fall into 4 basic types: copper oxychloride and copper sulfate (e.g., C-O-C-S WDG); copper hydroxide (e.g., Kocide 2000, Champ Formula 2); complexed forms of basic copper sulfate (e.g., Cuprofix Disperss), and copper salts of fatty and rosin acids (e.g., Tenn-Cop). Dust preparations (e.g., C-O-C-S Copodust) are also available. All copper fungicides work by releasing free copper ions, so activity (and potential phytotoxicity) is usually related to the amount of actual metallic copper that is applied to the crop.
