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...

Some thoughts on the future strategy for eradicating Serpula lacrymans from a building
1989 - IRG/WP 1405
We now have a clear view of the mechanism of translocation of nutrients in the mycelium of Serpula lacrymans which is one of the physiological processes underlying the remarkable capacity of this fungus to spread through a building. Here the elements of the mechanism of translocation are dissected out to suggest avenues which might be followed in the search for new ways for eradicating the fungus ...

Lignin-copper, a new wood preservative without arsenic and chromium
1992 - IRG/WP 92-3702
A more environmentally sound treatment for wood with preservatives containing no arsenic or chromium, has been developed and studied on a laboratory scale. The method involves a first step impregnation with an aqueous solution containing modified, water-soluble kraft lignin followed by a second step involving impregnation with a copper salt solution to give fixation of the lignin into a water-inso...

Methane emission by termites, Coptotermes formosanus Shiraki
1995 - IRG/WP 95-10099
Association of methanogenic bacteria only with the smallest-sized symbiotic protozoa Spirotrichonympha leidyi Koidzumi was evidenced by epifluorescence microscopic observations. Workers, which were collected from a laboratory colony and placed in a test container with water supply emitted methane at a relatively constant rate with a peak of 0.76 nmol/termite/hr within the first 72 hrs after the in...

Sub-group on Basidiomycete tests: Proposals for Sub-group programme of work
1979 - IRG/WP 2127
During the IRG 10 Meetings in Peebles, Scotland in September 1978, it was resolved to establish within Working Group II a sub-group on testing wood preservatives against basidiomycete fungi. The terms of reference and scope of the sub-group's activities were to be determined by consensus among members who registered an interest. Dr A F Bravery (PRL, UK) was asked to act as co-ordinator. D...

A comparison between methods for evaluating the water repellency of wood
1989 - IRG/WP 2328
Wood specimens treated with a number of water repellent formulations have been tested for their water repellency according to four laboratory test methods, based on weight increase, swelling and contact angle measurements, in order to assess the degree of agreement between the different methods. Treatments representing formulations with a wide range of water repellent efficiency were tested both i...
