The incidence of treated wood in a recycling stream was assessed at a recycling center in western Oregon. Chromated copper arsenate (CCA) was the predominant treatment present in the material, ranging from 0 to 2 percent of the material present at any given time. Treated wood was present at 38...
Mold and stain fungi can be easily controlled by kiln-drying, but even this material can be rewetted during shipping and storage, allowing fungi to colonize the wood. The potential for using surface spray treatments with commercial formulations containing combinations of propiconazole, didecyldimethyl ammonium chloride, or 3-iodo-2-propynyl butylcarbamate to protect kiln-dried...
The potential for moisture sorption by boron and fluoride rods following application of rods to wood to affect subsequent chemical diffusion was investigated in small Douglas-fir blocks conditioned to 30, 60, or 90 percent target moisture content (MC). MCs tended to decline over the 180-day test period, but there was...
The potential of 17 hydroxylamine derivatives as wood preservatives was assessed on ponderosa pine sapwood blocks exposed to one of two decay fungi: Gloeophyllum trabeum or Trametes versicolor. Weight losses on untreated controls were generally lower with the white-rot fungus (T. versicolor) averaging 30.4 percent, while those for the brown-rot...
