Thermal treatment of southern pine timbers with borates
Green, partially seasoned (air-dried, steam conditioned), or kiln-dried southern pine timbers were treated thermally using 15 percent disodiumoctaborate tetrahydrate solution. After treatment, sections were stored under nondrying conditions to allow […]

Tolerance of Poria Species to Copper-Based Wood Preservatives
Cultures of 35 species of Poria were tested against copper chromate and copper-chrome-arsenate in soil block tests and against copper sulphate in nutrient agar. Wood blocks used were of Pinus […]

Tolerance of Some Canadian Strains of Wood-Rotting Fungi to Wood Preservatives
Eleven strains of wood-rotting fungi from six species, frequently isolated from wood in service in eastern Canada, were tested for tolerance to sodium arsenate (Na2HAs04), pentachlorophenol (PCP), sodium fluoride (NaF), […]

Toxicity of B, B’-Oxydipropionitrile Soluble and Insoluble Fractions of Creosote and Petroleum Oils to Wood-Destroying Fungi By the Soil-Block Method
The selective solvent (B,B’-oxydipropionitrile) can be used to separate petroleum and coal tar oils boiling in the creosote range into two fractions, one of which is much more toxic to […]

Toxicity of methyl bromide to four pathogenic fungi in larch heartwood
Toxicity of methyl bromide to representative pathogenic fungi was tested by exposing Armillari ostoyae, Heterobasidion annosum, Lachnellula willkommii, and Leptographium wageneri grown in 1-cm media-amended Dahurian larch (Larix dahurica) wood […]

Treatability of ezo spruce and dahurian larch from the Russian Far East with CCA-B
The testability of ezo spruce and dahurian larch heartwood with CCA-Type B, and the effects of incising upon their treatability were investigated. When unincised, both species did not meet the […]
