Whole-of-house protection from subterranean termite attack and damage after four years of field exposure
2008 - IRG/WP 08-10665
This study reports the condition of the whole-of-house termite protection test in tropical Australia after four years. The study was designed to provide maximum protection to whole-of-house timbers in a natural situation posing the highest hazard from subterranean termite populations. The houses were constructed either on concrete slabs or suspended floors using untreated and treated timber fram...

Granitgard used as a partial and perimeter barrier in the protection of buildings against subterranean termites
1995 - IRG/WP 95-10114
The graded granite subterranean termite physical barrier, commercially marketed as Granitgard, has a Certificate of National Accreditation issued by the Australian Building Codes Board, and is included in Australian Standards. After several years in developing the specifications and installation techniques for Granitgard, it may be used to protect almost all footing designs. Granitgard can be simp...

Development of a Granitgard® particulate termite barrier for use in tropical Australia
1997 - IRG/WP 97-10190
Granitgard® is superficially simple technology; graded crushed aggregate, sieved to a size range impenetrable to subterranean termites. However, behind this apparent simplicity lies a large research effort. In this paper we describe the laboratory development of a grading of Granitgard suitable for use against the wide range of termites which attack timber in northern Australia, above the Tropic ...

Heat treated timber in Finland
2000 - IRG/WP 00-40158
Heat treatment permanently changes the physical and chemical properties of wood by means of high temperatures (150 - 240°C). Heat treatment darkens the colour of the wood. Heat treatment improves the equilibrium moisture content of the wood and the shrinkage and swelling of the wood is reduced. Very high temperatures improve the resistance to rot and also reduce the susceptibility to fungal decay...

Feasibility of termite control using crushed cement-stabilized sludge (Polynite) as a physical barrier and acoustic emission (AE) monitoring
2000 - IRG/WP 00-10381
In Japan, the damages by the subterranean termites (Coptotermes formosanus Shiraki and Reticulitermes speratus Kolbe) are more common. Recently, the more attention is paid to the methods of the termite controls of less- or non-chemical. As one of the non- chemical treatment, physical barrier using particles as basalts 1) , granites, and gravels 2) were investigated in terms of its safety, cost eff...

Chemical, physical and biological factors affecting wood decomposition in forest soils
2003 - IRG/WP 03-20281
Organic matter (OM) decomposition is an important variable in determining the potential of forest soils to sequester atmospheric CO2. Studies using OM from a particular location gives site-specific decomposition information, but differences in OM type and quality make it difficult to compare results among soils and forest ecosystems. By using a “standard” OM in decomposition studies, OM qual...

Termite physical barriers: Is retrofitting with Granitgard an option?
1993 - IRG/WP 93-40011
Granite particles within the range of 2.4 to 1.7 mm diameter were recently adopted by the Standards Association of Australia as an alternative treatment to soil chemical barriers in protecting new buildings against subterranean termites. The granite substrate is sold under the commercial name, "Granitgard". However, there are many existing buildings that have no chemical or physical subterranean t...

FLUROX, a new breakthrough in insect control for wood preservation
1995 - IRG/WP 95-30079
FLUROX (flufenoxuron) is an acylurea insecticide which acts as a growth regulator in insects. FLUROX inhibits the production of chitin - the exoskeleton or 'skin' of the insect. When the exposed larva attempt to moult to its next stage of development, it is unable to produce a new skin and dies. FLUROX has been found to be extremely active against wood borers, when applied in a p...

Efficacies of physical barriers for preventing blue-stain of Japanese red pine logs
2007 - IRG/WP 07-20359
This paper deals with field trials on physical barriers to prevent blue stain on Japanese red pine logs using a fly screen, bark and leaves of Japanese cedar as covering materials. These barriers arrested blue stain and bark beetle attacks to low levels than control for 1 month except covering with a small amount of bark. Covering with the fly screen and a large amount of bark permissibly suppress...
