Use of freeze disinfection for the control of the common furniture beetle Anobium punctatum
1992 - IRG/WP 92-1528
The common furniture beetle Anobium punctatum is an extremely widespread pest of wooden objects in Danish museums. In order to develop non-chemical methods of controlling the pests, experiments were conducted to elucidate the lower lethal temperature of Anobium punctatum. The egg stage was used for the experiments as it is considered the most temperature resistant stage. Groups of Anobium punctatu...

Collaborative tests on the influence of solvent and drying method on the toxic limit of wood preservatives against Basidiomycetes
1974 - IRG/WP 248
Seven institutes from five countries, Austria, England, France, Germany and the Netherlands have collaborated in a study on the influences of solvent and drying method on the toxic limits of wood preservatives against Basidiomycetes tested according to the agar-block method. Two preservatives, a 25% pentachlorophenol-concentrate and tributyltinoxide were applied to pine sapwood and beech and teste...
In vitro sporulation of selected wood decay fungi
1978 - IRG/WP 190
Basidiospores produced axenically without laborious attention in the laboratory are useful in studies of wood decay initiation. Such spores presumably approach those collected from natural sporophores in size and germinability (Morton, 1964). Production of spores in vitro by inversion of cultures grown on 2% malt extract agar in deep glass dishes (100x80 mm²) has been the preferred method (Morton...

The effect of preservative distribution in small blocks of Pinus sylvestris on the toxicity of tributyltin oxide to Reticulitermes santonensis Feytaud
1971 - IRG/WP 206
Small blocks of Pinus sylvestris (50x25x15 mm³) were treated by a full-cell method with various concentrations of tributyltin oxide in benzene. Replicate blocks were then freeze dried, rapidly air dried or slowly air dried and exposed to surface attack by the subterranean moistwood termite Reticulitermes santonensis Feytaud. At all concentrations it was found that the freeze-dried blocks were mor...

Development of a disinfection treatment for oak logs to be imported from the USA
1984 - IRG/WP 3283
The European veneer industry depends greatly on oak supplies from the USA. To prevent the accidental introduction of the American Oak Wilt Disease (Ceratocystis fagacearum) into the member states of the EC, a disinfection treatment was developed for oak logs under consideration of the technical requirements of veneer production. Laboratory experiments and field trials in Germany and in the USA sho...

Investigation of extracellular mucilaginous material in some wood decay fungi
1996 - IRG/WP 96-10188
The external morphology of the extracellular mucilagenous material (ECM) produced by Coriolus versicolor and Coniophora puteana during colonization of Scots pine and beech was studies using SEM. Specimens were examined in the frozen hydrated, freeze-dried and critical point dried state. All technics produced artefacts but the ECM was best preserved when examined the frozen hydated state. Critical ...

Co-operative tests concerning influence of solvent and drying method on the toxic limit of wood preservatives against Basidiomycetes. Preliminary report
1971 - IRG/WP 204
In the Working Group II of the Organization for Economic Co-operation and Development working group on wood preservation (now International Research Group on wood preservation) it was agreed that more knowledge was necessary concerning the influence of the solvent on the toxic limit of organic solvent types of wood preservatives against Basidiomycetes. A test program was drawn up and after discuss...
Co-operative tests concerning the influence of solvent and drying method on the toxic limit of wood preservatives against Coniophora cerebella
1972 - IRG/WP 216
In the working group II of the IRG it was agreed that more knowledge was necessary concerning the influence of the solvent on the toxic limit of organic solvent types of wood preservatives against Basidiomycetes. A test program was drawn up and after discussion in the mentioned working group the final program was accepted by the co-operating institutes in 1969. In the test program two fungicides, ...
Recommendations for handling of mold infestation of wooden artifacts
2012 - IRG/WP 12-10790
The presentation gives an overview of the handling of wooden artifacts with mold infestation. The causes of mold deterioration are demonstrated by investigations in a church, a historic library and a monastery in Germany. Investigated infested wooden artifacts were altars, sculptures, picture frames and sarcophagi. Important investigation methods including indoor climate measurement, material an...
