Abstract: Wood kilns, electrode systems for wood kilns, and methods of using the systems for the radiofrequency (RF) drying and phytosanitizing of wood are provided. The electrode systems are based on a three-electrode design in which a central plate electrode having winged edges is disposed between a pair of ground plate electrodes. The winged edges of the central electrode improve the uniformity of heating during the phytosanitizing process, relative to a five-electrode parallel plate system, or a three-electrode parallel plate system having a conventional planar central plate electrode.

Abstract: A method for treating wood packaging materials using Radio Frequency heating includes the steps of heating wood packaging materials using RF heating and applying a pressure before the heating or incrementally applying a pressure during the heating. The wood packaging materials are heated in a RF operating unit that has a sealed chamber with an inner surface and a liner cover a majority of the inner surface, the liner having a heat-reflective inner face and an insulation layer between the inner face and the inner surface.

Abstract: A method for treating wood packaging materials using Radio Frequency heating includes the steps of heating wood packaging materials using RF heating and applying a pressure before the heating or incrementally applying a pressure during the heating until a temperature of the wood packaging materials reaches at least 60° C. and that temperature is maintained for at least 1 minute.

Abstract: A method for destroying bacterial spores, germs, and the like is disclosed, comprised of a non-contact ultrasound device that produces ultrasonic beams transferred in ambient air without the use of a liquid medium in frequencies ranging between 50 kHz to 5 MHz. The method of the present invention can be used as a germicide for destroying anthrax spores and other highly toxic microbes that may be used as an agent of bioterrorism.

Abstract: A method of enhancing baculovirus disease in pests on a crop is provided through an insect control composition by applying an insect control composition to the crop. The applied composition includes a baculovirus that is infectious for at least one pest feeding on the crop and an enhancing agent for the baculovirus. The enhancing agent is preferably administered so as to be ingestible by the pest together with the baculovirus. A preferred enhancing agent is mannitol which increases the mortality of larval tobacco budworms feeding on cotton when infected with Autographa californica by 238%.
