Retreatment of Spent Creosote-Treated Wood with Copper Hydroxide and Sodium Tetraborate

Bessie Woodward, William Abbott, Michael West

Abstract

Southern pine sapwood blocks, treated with creosote at sub-threshold level, were retreated with either copper hydroxide or sodium tetraborate and evaluated by laboratory soil-block tests to determine efficacy of retreating creosote-treated wood with short chain amino copper compounds and borates. The unexpected copper synergism with creosote confirms that amine copper complexes from copper hydroxide are highly synergistic with creosote for controlling Neolentinus lepideus, the creosote-tolerant fungus. The compatibility of copper hydroxide and sodium tetraborate decahydrate with creosote suggests that these chemicals can be used effectively for retreatment of creosote poles.
