Data for: Evidence to support phytosanitary policies - The minimum effective heat treatment parameters for pathogens associated with forest products

Research on reducing the movement of pests on wood products has led to several options for safer trade including heat treatment of wood to mitigate pests. In this study, pathogenic organisms commonly regulated in the trade of forest products were tested to determine the minimum heat dose (temperature and time) required to cause mortality. The mycelial stage of tree pathogens, Heterobasidion occidentale, Grosmannia clavigera, Bretziella fagacearum, Phytophthora cinnamomi, P. lateralis, P. ramorum and P. xmultiformis, which may be found in wood products, were tested in vitro using the Humble water bath with parameters simulating the rate of heat applied to wood in a commercial kiln. The lethal temperature for the pathogens ranged from 44 to 50°C for a 30-minute treatment duration. A molecular diagnostic method to confirm pathogen mortality was available for five of the species heat treated. RNA detection using reverse transcription real-time PCR was used to validate pathogen mortality fol..., The data are observations on post-treatment survival of Heterobasidion occidentale, Grosmannia clavigera, Bretziella fagacearum, Phytophthora cinnamomi, P. lateralis, P. ramorum and P. xmultiformis exposed to heat in a water bath. The experiments were used to determine the optimal heating conditions for treatment of wood infested with forest pathogens. The mycelial stage of pathogens growing on grain were exposed to temperatures from 40 up to 52 degrees celsius for 30 minutes. Heat-treated and unexposed control grains with mycelium were plated on 20% V8 agar for Phytophthora species or 2% malt extract agar with yeast extract for fungi and observed for growth to determine if they survived treatment at each of the exposure temperatures., , # Data for: Evidence to support phytosanitary policies -The minimum effective heat treatment parameters for pathogens associated with forest products
