Forest products laboratory methodology for monitoring decay in wood exposed above ground
1995 - IRG/WP 95-20074
Research at the Forest Products Laboratory on the durability of wood in service has included a full complement of laboratory and field tests. In this report, we present a review of past and current methods used to evaluate the condition of preservative-treated wood exposed above ground. Current protocols are described for tests on wood packaging, roofing, and dimension lumber....

Regulatory and Consumer Challenges Facing Timber Preservation and Durability Interests in New Zealand and Australia
2003 - IRG/WP 03-20282
Timber preservation and durability interests in Australia and New Zealand are facing many challenges and threats arising from regulation and standards changes, to direct competition from competitive materials producers. Industry can address these challenges by pro-active initiation of sound, holistic, research, that addresses the performance needs of the regulators and specifiers and the expectati...

Sex pheromone of the male house longhorn beetle Hylotrupes bajulus (L.) (Coleoptera: Cerambycidae)
1995 - IRG/WP 95-10100
Since 1990 studies have been conducted with respect to the chemical communication of the house longhorn beetle Hylotrupes bajulus (L.) (Coleoptera: Cerambycidae). The structure of glands located in the prothorax of the beetles was examined with light and scanning electron microscopy. The analyses of different extracts from beetles resulted in the finding and identification (GC-, GC/MS-, and HR-GC/...

Proposed degradation pathway for quaternary ammonium compounds by mould fungi
1996 - IRG/WP 96-10166
One group of chemicals that has attracted considerable attention as potential wood preservatives are the quaternary ammonium compounds (QACs). Based upon results of previous research this study confirmed the degradation pathway employed in QAC-tolerant fungi. For this experiment the two dialkylammonium compounds didecyldimethylammonnium chloride and dioctyldimethylammonium chloride were used. QAC-...

Evaluation of the leach resistance and preservative efficacy of novel biocides as surface treatments applied by brush to spruce (Picea abies)
1998 - IRG/WP 98-30170
The comparative leach resistance and preservative efficacy of a number of alternative organic preservatives (available from Zeneca Specialties) and selected commercially available biocides as surface coatings to wood in Hazard Class 3 have been assessed. Two concentrations of test preservatives were applied by brush to Spruce (Picea abies), including formulation and untreated controls. A leaching ...

Wood preservation and the environment: A Canadian perspective
1990 - IRG/WP 3577
The non-pressure (surface) and pressure treatment of wood impacts on the environment in four ways. These are: through the production of treated wood at sawmills and pressure treating facilities; during the storage of treated wood prior to use; when the pressure treated wood is placed in service; and finally, when the treated product reaches the end of its useful life and must be disposed. By refer...

Effects of some essential oils on wood destroying organisms
1993 - IRG/WP 93-10047
Three wood destroying fungi: Botryodiplodia theobromae Pat. (stain), Gloeophyllum sepiarium (brown rot), and Pycnoporus sanguineus (white rot) were exposed to six plant essential oils: the peppermint, kaffir lime or leech lime, lavender, tarragon, holy basil, and the eucalyptus. The peppermint oil showed most effective to inhibit fungal growth, while eucalypus oil was the least effective. The othe...

In ground contact field trial results of preservative treated incised and unincised spruce
1996 - IRG/WP 96-40076
Field trials of treated spruce stakes have been demonstrated that incising the stake before treatment improves the preservative uptake both for CCA and creosote. This results in a substantially extended service life for the incised stakes over the unincised stakes for preservative concentrations at commercial levels. After 24 years in ground contact the majority of incised spruce samples are sound...

Studies on the preservation of structrual plywood - Part 1: Decay resistance of structural plywood
1974 - IRG/WP 238
The weight loss and the decreases in the compression strength and in the modulus of elasticity were measured to determine the decay resistance of structural plywood (lauan). Test pieces (50x25xA mm³) were exposed to the wood destroying fungi (Coriolus versicolor and Coriolellus palustris) for 2-3 or 2-4 months. After exposure, the measurement of the compression strength was carried out on the pie...
