Xanthomonas blight on hellebore.Copper fungicides represent one of the oldest active ingredients developed to fight plant diseases. Some of the first fungicides developed contained copper and were used to combat diseases of vines (i.e., black rot) and fruit (i.e., apple scab).

In the 1800s copper sulfate pentahydrate was formulated with lime into Bordeaux mixture. Many other types of copper products followed with basic copper carbonate and copper ammonium carbonate first used in 1887, copper oxychloride in about 1900 and cuprous oxide in 1932.   Safer and more effective copper fungicides have been developed including copper linoleate (Camelot in 1964) and copper hydroxide in 1968. The copper products now used on ornamental plants are primarily Camelot, Junction, Kocide and Phyton 27. There are other copper products that are used in some portions of the ornamentals market.
