Heat treatments have been successfully used for eradication of dry rot. The effect of heat treatments at 40, 50 and 60°C for various time intervals on the inactivation of Penicillium brevicompactum was determined. The effect of heat on ungerminated spores and spores "pregerminated" for 24 hours was evaluated by plating on malt-extract agar. Although most ungerminated spores were inactivated after 5 h at 50°C, complete inactivation of ungerminated spores required 60°C for 30 h. Treatment at 60°C for 18 h inactivated the fungal mycelia on wood, as determined with ATP measurements.
