INVESTIGATION OF CHEMICAL PRESERVATIVES AND NATURALLY RESISTANT WOODS FOR LONG-TERM BORER PROTECTION

Six chemical wood preservatives were selected for evaluation over long periods of exposure in extremely borer-active marine environments in the Panama Canal Zone. Southern yellow pine and Douglas fir were full-cell pressure-treated with these chemicals and exposed in tropical seas and tropical brackish water for periods up to 90 months. One hundred and thirteen untreated tropical wood species were concurrently exposed in these same waters. The long-term results show that heavy treatments of whole creosote and chromated copper arsenate (CCA, type A) are very effective preservatives for southern pine exposed in seawater and that the CCA was the singularly most effective treatment against the brackish-water Psiloteredo.
