Developements in the EEC on the regulation of wood preservatives
1993 - IRG/WP 93-50016
There is a wide variation in the regulation of wood preservatives within the EEC, ranging from product by product authorization under persticides legislation to controls via standards, or simple compliance with basic requirements on classification packaging and labelling. During the past two years the commission of the European Communitiesn has worked on a proposal concerning the placing on the ma...

Laboratory evaluation of borate formulations as wood preservatves to control the subterranean termite coptotermes acinaciformis (isoptera: Rhinotermitidae) in Australia
2001 - IRG/WP 01-30266
The termiticidal efficacy of Borocol (sodium octaborate tetrahydrate), boric acid, bore-ester-7 and tri- methyl borate was evaluated in laboratory bioassays against Coptotermes acinaciformis (Froggatt). Seasoned sapwood blocks of Pinus radiata D. Don, and Eucalyptus regnans (F. Muell) were impregnated with the various borate compounds. There were marked differences in mass loss and mortality rate ...

Report on the burning of wood treated with wood preservatives containing copper, chromium and arsenic
1976 - IRG/WP 379
Mixtures of copper, chromium and arsenic salts are used extensively in the UK to preserve timber. This report is concerned with the fate of these metals when timber treated with these salts is burned. A large percentage of the arsenic present in the timber is shown to be volatilised during combustion and the potential environmental implications of this are assessed by comparison with the release o...

A collaborative test to determine the efficacy of polyurethane coatings on wood samples in the marine environment. 2nd Interim Report
1990 - IRG/WP 4161
The results of a collaborative international test to evaluate the performance of elastomeric polyurethane coatings of wooden test samples exposed in seawater at 13 sites around the world are reported. The samples have been exposed at sites with known infestations by molluscan and/or crustacean wood borers. Performance data for up to 4 years exposure at some sites is presented providing information...

Wood Preservation India; Current Scenario
2013 - IRG/WP 13-40630
This short note describes the present status of wood preservation research and its industrial application. Although good performing formulations have been developed by Indian research laboratories, industry has not tried to derive benefits from this development. Many unknown products are flooding the market for brush on applications with little benefit as the products have not been standardized....

The mathematical study of test plot data
1987 - IRG/WP 2282
It has long been desirable to have a mathematical expression, which, by the insertion of statistically derived constants, would describe the behavior of test specimens in service. The philosophy of such expressions is briefly discussed, and the history of the concept is outlined. The modern approach to the problem dates from the graphical presentation of dosage-response and deterioration curves by...

Presteaming radiata pine heartwood to improve treatability
1983 - IRG/WP 3239
Steaming and holding before preservative treatment by the Bethell process greatly improved the treatment of radiata pine heartwood. Maximum penetration of preservative for the shortest holding period was obtained by the use of steam vacuum but the difference between this and steam venting was small when compared with the standard of treatment of air dried samples. A holding period of one day was s...

Fixation and leaching of selected Malaysian tropical hardwood after treated with CCA
2001 - IRG/WP 01-40207
The objective of this study is to investigate the fixation and leaching properties of selected Malaysian tropical hardwood (sentang wood (sapwood and heartwood) and rubberwood) after being treated with copper chrome arsenate (CCA) type-C preservative. The samples were treated with retention level of 0.5%, 2.0% and 5.0%. The samples were leached and the leachate were analyzed by AAS and the amount ...

Yeasts associated with the infrabuccal pocket and colonies of the carpenter ant Camponotus vicinus
2000 - IRG/WP 00-10335
Yeast associations in three colonies of Camponotus vicinus were examined in two different areas of western Oregon. We sampled the exo-cuticle, infrabuccal pocket contents of worker ants, interior galleries of each colony and detritus and soil in the area adjacent to the nest. Samples were plated on yeast-extract-malt-extract agar augmented with 1M hydrochloric acid and incubated at 25°C. Yeasts w...

Evaluation of Barrier Wrap Systems after 71 Months of Exposure
2013 - IRG/WP 13-40631
A 71 month study of the performance of booted samples in ground contact was conducted in AWPA hazard zone 4. Data indicated that excellent performance of wrapped systems, even over untreated wood, could be obtained. Instances of decay colonization or termite attack could all be attributed to some breaking of the integrity of the barrier system. Good performance for treatment below ground contact...
