When impregnated into wood test panels, creosote, coal tar, 70-30 creosote-coal tar solution, tributyltin coconut fatty acid salt, and tributyltin oxide, in general, give protection against Martesia and teredine Teredo attack but not against Limnoria. Inorganic copper and mercury compounds, phenylmercuric oleate, dibenzofuran, fluorene, and toxaphene protectAGAINST Limnoria attack only. Resistance to Limnoria attack, without adversely affecting resistance to Martesia and Teredo, is increased by the addition to creosote of aluminum, copper, or manganese oxinates, and dieldrin, phenylmercuric chloride, or phenylmercuric oleate by the addition to coal tar of copper naphthenate or phenyl-mercuric oleate and by the addition to a 70-30 solution of creosote-coal tar of copper naphthenate, dieldrin, endrin, phenylmercuric chloride, or phenylmercuric oleate. Combinations of copper compounds or complexes plus oxine or polyvinylmethyl ether-maleic anhydride, and dieldrin or endrin plus malachite green oxalate are resistant to Limnoria and teredine borers but not to Martesia.
