Treatability of plywood containing intermountain Douglas fir veneers
1982 - IRG/WP 3203
Eighteen sheets of plywood were obtained which contained intermountain Douglas-fir veneers from two regions of British Columbia. Following pressure treatment with chromated copper arsenate (CCA type C) and ammoniacal copper arsenate (ACA) the preservative penetration and retention in individual veneers was assessed. It was concluded from the study that the intermountain Douglas-fir veneer could no...

Survey of conditioning treatment practices in India
1978 - IRG/WP 3127
India has 75.3 million hectares (ie about 24% of total land area) under forests out of which the area of productive forests, from which industrial wood is available, is about 60 million ha. The Task Force on Forest Resources Survey has tentatively estimated that the total growing stock in Indian Forests is 24,000 million cubic metres (m³). The total recorded production of wood in the country is r...

Système informatisé d'aide à la décision pour la gestion de la migration du pentachlorophénol dans l'environnement
1993 - IRG/WP 93-50001-10
This paper describes a Decision Support System (DSS), concerning pentachlorophenol (PCP) migration in the environment. The principal objectives of the DSS are to assist managers in siting of PCP-treated poles in the Hydro-Québec system and the storage areas and in the treatment of customer complaints. Four mathematical models are incuded in the system: a model simulating migration inside and on t...

Evaluating the Exterra Termite Interception and Baiting System in Australia
2003 - IRG/WP 03-20267
The Exterraä Termite Interception and Baiting System (Ensystex Inc., Fayetteville, NC) was evaluated in a field experiment near Townsville, Australia. Cellulose-acetate powder containing either 0.05% weight/weight (w/w) or 0.25% w/w chlorfluazuron (Requiemä) was tested for its efficacy in eradicating colonies of the mound-building subterranean termite Coptotermes acinaciformis (Froggatt). Thirte...

Framework document for an international code of good practices for wood preservation and wood protection (anti-sapstain) facilities
1992 - IRG/WP 92-3683
At the Kyoto meeting, the Health & Safety committee agreed to form a task force to prepare a global plan for writing a code of good practices (Code) for wood protection and preservation facilities (Doc. No. IRG/WP/3681). The Canadian document had been presented to the IRG group earlier (Doc. No. IRG/WP/3447) and similar documents were solicited from other countries for preparing a framework do...

IRG/COIPM INTERNATIONAL MARINE TEST - to determine the effect of timber substrate on the effectiveness of water-borne salt preservatives in sea-water: Final report
1987 - IRG/WP 4133
Three timbers chosen as reference species were treated with 3, 6 and 10% solutions of CCA and CCB preservatives and exposed for up to 93 months at 8 tropical and temperate marine sites. Eleven local species treated in the same way were exposed at 4 of the 8 sites. There was no apparent difference in performance between CCA and CCB treated specimens. The severest test site was Panama Canal but mari...

The biological natural durability of timber in ground contact
1994 - IRG/WP 94-20051
The BRE ground contact field trials for the determination of the biological natural durability of different timber species have recently been reviewed. The data obtained from these trials have been used to appraise the different ways in which natural durability may be expressed. It is concluded that the use of the mean as a method of assigning the timber to one of five durability classes may be ac...

Laboratory and field evaluation of Plasmite Reticulation System using bifenthrin as a chemical barrier within wall cavities against subterranean termites.
2005 - IRG/WP 05-20307
Laboratory and field bioassays undertaken to demonstrate Plasmite Reticulation system effectively delivers the termiticide (bifenthrin) within a simulated wall cavity at the required concentration. The chemical assay indicated that the amount of bifenthrin sampled at 5, 10, 15, 20, and 25m along the simulated reticulation system tested (30m) exceeded the manufacturer’s minimum recommendation of ...
