Abstract : Test takes of southern yellow pine sapwood 2 by 4 in. (nominal) by 18 in. in size were treated by pressure and nonpressure processes and in stalled by the Forest Products Laboratory and cooperators in decay and termite exposure sites at various times since 1938. Also included in the tests are smaller pine stakes and those of treated and untreated plywood, modified woods, laminated paper plastic, and pine infected with Trichoderma mold. Southern yellow pine untreated control stakes have had an average life of about 1 year in the Canal Zone, 2 to 3 years in Mississippi, Florida, and Louisiana, and about 6 years in Wisconsin. Superficial treatments by dipping and brushing with preservatives such as coal-tar creosote and petroleum oils containing copper naphthenate, zinc naphthenate, phenyl mercury oleate, and pentachlorophenol have added a few months to 4 years to the life of the untreated stakes.
