Copper is the most common ingredient in waterborne preservatives and provides excellent activity against most fungi and insects. However, issues associated with copper migration from treated wood have created increasing concerns about potential risks to non-target organisms in surrounding environments, especially those in sensitive aquatic environments. Various Best Management Practices...
Resistance to moisture uptake is an important attribute of some wood preservatives and can help reduce moisture cycling that leads to the development of deep checks. While the potential for preservative treatments to help improve wood/moisture interactions is acknowledged, there are no tests that specifically evaluate this performance parameter. Checking...
It is difficult to treat the heartwood of many wood species with liquid preservatives using conventional liquid processes. Supercritical fluids (SCF) used as carriers of preservatives to impregnate refractory wood species may be an attractive alternative to conventional liquid carriers. While SCF impregnation has many potential advantages, some wood species...
The potential of 9 bacterial and 6 fungal isolates to
protect wood against wood staining microorganisms was
studied using small sapwood samples of unseasoned Ponderosa
pine [Pinus ponderosa Laws] sapwood. Bacillus subtilis Cohn,
isolate 733 A , Gliocladium virens J.H. Miller, J.E. Giddens
& A.A. Foster isolate H 3 and...
