Effect of asphyxiation on wood decay fungi treated
with argon and nitrogen gas
2002 - IRG/WP 02-10452
The effects of low-oxygen conditions, achieved with either argon or nitrogen gas, on the viability of wood decay fungi Coniophora puteana, Antrodia vaillantii and Trametes versicolor, cultivated on PDA medium and infected wood samples, were examined. The fungal cultures were exposed to low oxygen concentration (below 10 ppm) for one to five weeks in hermetically sealed vessels. Anoxic treatment di...

Investigation of microwave as a means of eradicating dry rot attack in buildings
1992 - IRG/WP 92-1545
A microwave-apparatus developed for treatment of building-structures infested by dry rot was tested in the laboratory. The test-conditions simulated treatment of either infested timber or infested brickwork. Sawdust samples, both wet and dry, infested by viable mycelium of Serpula lacrymans were packed in glass-tubes. The tubes were then placed in the middle of either 20 cm thick wooden beams or 3...

Experiences from a Danish large scale test by means of a new method of treatment by attack of true dry rot fungus (Serpula lacrymans) in buildings
1994 - IRG/WP 94-10064
Experiences from a new and epoch-making method of treatment in connection with the repair of attack of the true dry rot fungus, Serpula lacrymans (Fr.) S.F. Gray, are described. The paper presents the background of a large scale test comprising repair of more than 150 Danish buildings over a period of approximate 5 years. The method being both gentle to the building and presenting savings of at le...

Technical viability of deltamethrin as a pre-treatment wood preservative
1993 - IRG/WP 93-30012
This paper presents the results of tests conducted on freshly-cut logs and lumber during the seasoning period to verify the effectiveness of Deltamethrin on insect control. The tests were carried out in Quedas do Iguaçú, Paraná (southern region of Brazil) and Breves, Pará (northern region of Brazil) during the-dry and rainy seasons, and used different species of wood and insecticide/fungicide ...

Biofumigation of sapstaining fungi using natural products
2002 - IRG/WP 02-10428
Control of deep-seated fungal infections in raw logs of radiata pine continues to be a challenge for achieving consistent and satisfactory protection of high value logs destined for export markets. To develop solutions for this problem, a study was undertaken to investigate inhibition of spore germination and growth of sapstaining fungi by volatiles released from a selection of natural products.

New experiences with Dry Rot in Danish buildings, heat treatment and viability tests
1989 - IRG/WP 1423
An increasing number of concealed dry rot attacks, especially in older multi-storey houses under renovation, have been detected during the last few years. A necessary consequence is a demand for cheaper methods of repair, compared to the standard method used in Denmark for many years otherwise severely attacked houses will by pulled down. A heat-treatment has been developed and tested in practice....
