Zusammenfassung

Over 400 million  m3 of standing lodgepole pine timber in the forests of British Columbia, Canada, is affected by the mountain pine beetle and associated ophiostomatoid fungi that stain the sapwood of infected pine trees a blue-grey color (Lee et al. 2005). Such staining is undesirable in appearance grade wood products and some grades of structural timber, and a simple method of removing the stain or reducing its severity is required. This study screened a range of bleaching agents to determine which ones were most effective at removing the blue stain and then optimised treatment parameters for the most efficient bleaching agent (sodium hypochlorite).
