This paper reviews the wood preservative biocide active ingredient copper and delvers into new and previously unpublished data regarding the new micronized formulations which are now in vogue and widespread use in N. America in all residential treated lumber markets. Included in this review is the overall discussion of copper containing formulations used for pressure treated wood used over the last century, and the systems currently in use, worldwide today. Also included in this work, is a long needed thorough review of copper’s mode of action, environmental issues, discussion of copper tolerant fungi issues, leaching and permanence, and efficacy toward a wide array of both fungal and insect species.
