The Naval Civil Engineering Laboratory is exposing wood panels impregnated with various materials to determine the resistance of these panels to attack by marine borers. The report lists the results of harbor tests of treated panels removed from exposure between 15 February 1967 and 15 November 1968. It also lists all treated panels which are being exposed and which have shown no attack or insufficient attack to warrant removal. When impregnated into wood test panels, creosote and 70-30 creosote-coal tar solution are about equally effective against martesia and teredinid attack, but the addition of certain organic and organometallic compounds to creosote or creosote-coal tar solution produces a preservative which is superior to creosote or creosote-coal tar solution alone. Certain creosote-free treatments which contain a combination of one material specifically toxic to limnoria and another material specifically toxic to teredines are superior to creosote or creosote-coal tar solutions in preventing marine borer attack.
