Abstract:

Southern pine untreated control stakes have had an average life of about 1 year in the Canal Zone 1.8 to 3.6 years in Mississippi, Florida, and Louisiana and about 6 years in Wisconsin. Superficial treatments by 3-minute 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. Some waterborne preservatives have provided less protection to the stakes than the standard preservative oils, such as coal-tar creosote and pentachlorophenol solutions, when preservative retentions have corresponded to those in commercial use. Other waterborne preservatives have shown excellent results in the exposure tests. Modified author abstract
