Abstract : Biological and chemical evaluation of effectiveness against marine borers, particularly Limnoria tripunctata, of creosote and creosote preceded by waterborne copper compounds in wood coupons is made. Assays of outer 1/8 in. of exposed surfaces performed at six month intervals to determine if threshold of preservative at which attack occurs can be ascertained. Efficacy of creosote preceded by waterborne copper compounds as effective barrier for Teredo and Limnoria discussed. (Author)
