Heat disinfestation of mountain pine beetle-affected wood

"Exporters of lumber and logs are obligated by Canadian law to apply approved treatments for phytosanitary purposes. Heating to 56°C for at least 30 minutes in a kiln or heating chamber (56/30) is the most common treatment used for lumber and is also an internationally accepted method to treat wood packaging in order to eradicate pests of concern. This time/temperature combination was originally developed to eradicate pinewood nematodes and their insect vectors. Questions have arisen in the marketplace about the efficacy of such treatment against fungal pests, and recently for those associated with mountain pine beetle-affected lodgepole pine. This project looked into the effectiveness of several time/temperature combinations, in particular whether 56/30 kills a selection of mountain pine beetle associated fungi including bluestain fungi (nine isolates), Ambrosiella fungi (three isolates) and sap-rot fungi (six isolates) ... Additionally, this project determined to what extent air-drying and wood aging reduced the viability of embedded fungi and if slow drying rendered the fungi more heat tolerant."--Document.
