"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.

"This research focuses on studying the heat tolerance of sap-rot and heart-rot fungi found in beetle-killed wood. Specifically, the authors evaluate the 56/30 schedule and other temperature/time combinations. They also investigate whether slow air-drying increased the heat tolerance of the fungi. The generated data are expected to fill an important science gap on the fungi found in beetle-affected trees."--Document.

International trade in forest products constitutes an important component of the world's economy. Forest products may have pests associated with them that pose phytosanitary risks and could have the potential to be introduced and become established into importing countries. These risks may result in the implementation of phytosanitary requirements that could affect trade. This report presents current knowledge of the phytosanitary threats and potential risk-reducing measures associated with the global trade in forest commodities. Commodities discussed include: round wood, sawn wood, wood chips (treated and untreated), and plant parts and live propagative materials. As wood undergoes processing, its phytosanitary risks are generally reduced. For instance, greater phytosanitary risks are associated with international movement of round wood with bark. As bark is removed, and sawn wood is produced, the risks decrease significantly through this production process. Untreated and live forest products can present high phytosanitary risks. This review of commodity-based phytosanitary risks associated with the global movement of forest products provides the global phytosanitary community with scientific information regarding major pests associated with forest products and recommends effective approaches to mitigate associated risks.
