Abstract
Phytosanitary heat treatments of
Ceratocystis lukuohia and
Ceratocystis huliohia-colonized
Metrosideros polymorpha wood were evaluated using kilns. Wood poles subjected to a 22- to 34-day dehumidification kiln schedule with a heat treatment to 60°C to the poles' core. In vacuum kiln trials, logs were heated to 56°C at 70 percent log radius depth and the temperature maintained for 30 minutes. Neither
Ceratocystis species was isolated from heat-treated wood using carrot baiting, whereas both fungi were isolated from control logs held at ambient temperature. Results of this study offer kilnheating as a way to eradicate
Ceratocystis fungi from
M. polymorpha wood.
