Physical barriers and bait toxicants: The Romeo and Juliet of future termite control
1991 - IRG/WP 1503
Soil chemical barriers are considered by some to be the most important technique for protecting buildings against subterranean termites in Australia (and elsewhere), providing a barrier against termite penetration. However, there is no such thing as a barrier that is 100 per cent +protective. And given the worldwide problems of using organochlorine termiticides, public awareness of chemical pollut...

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 ...

Industrial wood preservation in Kenya. Present status – future prospects
2005 - IRG/WP 05-30385
Although some 50 years old, industrial wood preservation in Kenya does not appear to have technically, scientifically, and commercially evolved and contributed to significantly extend service lives of timbers, protect health and the environment, and curb unnecessary over-exploitation of forests. The population of the country has increased by 530% over the past 50 years; regular excisions have red...

International standards – which future?
2003 - IRG/WP 03-20277
A review of past and current activities at CEN/TC/38, within the scope of "wood durability, in relation with exposure" suggest that former activities linked to wood preservative efficacy shall formally include the balance safety/efficacy as a main part of the risk/benefit patterns. One way is an extensive development of liaisons. The case of OECD/CEN cooperation on emission assessment is a positiv...

Future insecticidal treatments for wood products
1980 - IRG/WP 3140
Protective measures involving chemical treatment of wood use only a narrow range of toxic materials which are divisible into two groups, (i) those that are water-soluble, (ii) those that are soluble only in organic solvents. It is generally true to say that, as far as protection against insects is concerned, the former are stomach poisons while the latter are largely (though not exclusively) conta...

Objectives of future collaborative soft rot tests
1972 - IRG/WP 209
Progress has been made towards acceptance of a defined laboratory test method for determining the toxicity of preservatives against soft rot fungi (Documents IRG/WP/201 and IRG/WP/208) and, at the 1971 meeting in Brussels, the framework of collaboration for the next phase of testing was discussed. Time available at Brussels did not permit restatement of objectives, consideration of the stages by w...

Benzalkonium chloride (an AAC preservative): Criteria for approval, performance in service, and implications for the future
1985 - IRG/WP 3328
The data base generated for benzalkonium chloride was considered adequate for commercial approvals, particularly after revision in late 1982. Field trials, although not part of the approval criteria, generally supported commercial use; decay observed in one test (post and rails) after 6 years' exposure would have resulted in some caution in setting retentions. No laboratory trial, nor fie...

The future for chromium in wood preservation
1985 - IRG/WP 3332
Most water-borne preservatives contain CrVI compounds, originally to reduce corrosion although now also to improve toxicant fixation. Chromium contributes to preservation and this is recognised in, for example, New Zealand and USA where chromium contents are included in calculations of overall preservative activity of CCA formulations, but chromium may also have anti-stain and joinery (millwork) p...

Wood preservation in Nigeria - Its increasing relevance, observed constraints and potential as a forest conservation option
1992 - IRG/WP 92-3732
The paper discusses the demand and supply of wood and wood products in Nigeria and points out that in view of the large population (88 million) and search for wood for housing and furniture, the demand exceeds supply. There is great shortage of industrial and domestic woods resulting in underutilization of installed machineries in forest industries and low profit margin. Under this prevailing cond...

Future termite control requires partnership between industry, government and people
2006 - IRG/WP 06-10586
Given the behaviour of the pest control industry, together with the housing and timber industries, and performance of the State regulatory agencies, it is not surprising that all of these groups were philosophically ill-prepared to consider alternative measures in June 1995. However, conditions have altered and there is an awareness of such alternatives. In future, termiticides will have propertie...

Exterior paint for the future - Will there be any dry-film preservatives left?
2017 - IRG/WP 17-50332
Wooden houses have a long tradition in several of the Nordic countries. Wood can be protected in various ways; constructional, chemically and by surface treatment. The use of various types of exterior paints as a surface treatment is a common way to prolong the durability of the wood. To further protect the painted surface against growth of fungi and algae, dry-film biocides remains an essential p...
