HARBOR SCREENING TESTS OF MARINE BORER INHIBITORS. VII.
Abstract
The Laboratory is exposing wood panels impregnated with various materials to determine their resistance to attack by marine borers. This report lists the results of harbor tests of treated panels removed from exposure between 15 August 1963 and 15 August 1964. It also lists all treated panels which have been exposed for 1 year or more 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 teredine attack, but neither is effective against Limnoria. The addition of certain organic or metal-organic compounds to creosote or creosote-coal tar solution produces a preservative which is superior to creosote or creosote-coal tar solution alone. Treatments containing a combination of one material specifically toxic to Limnoria and another material specifically toxic to teredine borers are also showing promise as preservative systems. Certain tropical woods have performed well at Port Hueneme but have failed at Pearl Harbor because of Martesia attack. (Author)
