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...

Visualization of inorganic element distribution in preservative treated wood by SEM-EDXA
2001 - IRG/WP 01-40208
SEM-EDXA was found to be an effective way of visualizing inorganic element distribution in wood as it was possible to examine some inorganic elements at the same time and map the concentration differences in color. Japanese cedar sapwoods were impregnated by vacuum treatment with CuAz or by pressure treatment with CCA preservatives and then distribution of Cu, Cr and As elements in wood were exami...

Report on biological control of decay in poles
1977 - IRG/WP 149
The following its a brief report on a preliminary experiment carried out for the United Kingdoms Midland Electricity Board during 1974-1975 to establish, under laboratory conditions, the potential controlling value of some non-decay fungi against Lentinus lepideus. Lentinus lepideus has been confirmed to be the commonest Basidiomycete causing decay in poles in the Boards area....

Antagonistic effect of Trichoderma spp. against Serpula lacrymans in the soil treatment test
1991 - IRG/WP 1473
Soil treatment tests for preventing growth of Serpula lacrymans were conducted using Trichoderma spp. as antagonists. Soil specimens tested were Kanuma-soil without organic matter and the horticultural soil which was collected from the test site of the stake test. Perfect efficacy of treatment with Trichoderma spp. was shown when the horticultural soil without sterilization was used as a soil spec...

The status of marine wood preservation in Papua New Guinea
1974 - IRG/WP 405
The life-expectancy of Papua New Guinea hardwoods in the marine environment has in the past been too short to be an economical proposition, a service life of six to twelve months being obtained from some of the timbers susceptible to marine wood borer attack. Consequently plans for wharves and other marine structures have specified the use of imported materials such,as steel and concrete. Due to t...

A method to evaluate the effeetiveness of bait application using a transferred nest of Coptotermes formosanus Shiraki (Isoptera: Rhinotermitidae)
1999 - IRG/WP 99-20161
Although a survey of monitoring stations can tell us the decline of termite activity after application of baits, it seems questionable to conclude an eradication of a Whole colony of subterranean termites if the termites move out their foraging territory. Only reliable method to ensure the success of bait application is to determine the absence of living termites in their nest in accordance with a...

Biological control of blue stain on wood with Pseudomonas cepacia 6253. Laboratory and field test
1989 - IRG/WP 1380
Pseudomonas cepacia strain 6253 was tested as a biological control agent on wood samples under laboratory conditions, as well as in the field. In the laboratory this bacterium controlled blue stain on Pinus radiata, but field test were not totally satisfactory. However, after 2 months of field test, the test samples were 1/3 to 1/2 less stained then the control samples....

Feasibility of AE (Acoustic Emission) monitoring for the detection of the activities of wood-destroying insects
1992 - IRG/WP 92-2416
The feasibility of acoustic emission (AE) as a nondestructive testing method for the detection of the wood destroying insects was investigated. AEs were detected from the wood specimens under feeding attack of sugi bark borers or powder-post beetles. However, the feasible monitoring area of an AE sensor is influenced by the attenuation of AE amplitude, so that this could be a problem in the practi...

Leachability of borate-modified oriented strandboard: A comparison of zinc and calcium borate
2002 - IRG/WP 02-40232
The leachability of boron in zinc and calcium borate-modified oriented strandboard (OSB) was investigated in this study. The leaching experiments were conducted by exposing edge-sealed OSB samples under running water for 8, 24, 72, and 216 hours. The results were compared with those from the unleached controls. Boron leaching of the modified OSB occurred upon the initial water exposure, and the le...

Wood preservation in Thailand
1983 - IRG/WP 3265
The report gives a background to Thailand and its timber resources, production and consumption. The history of wood preservation in the country and its modern industrial development are described. Its 19 preservation plants are listed and the production figures of the two major ones given. The wood preservatives in use are noted and the costs of treating a railway sleeper in three different ways c...

The secondary treatment of creosoted electricity poles with fused boron rods
1988 - IRG/WP 3485
After preliminary trials selected poles were treated at the groundline with fused boron rods. Early samplings showed that movement was slow in the dry heartwood but after six years the distributions obtained indicate that the system has merit for the treatment of the heartwood of poles in service....

Inhibition of termite feeding by fungal siderophores
1992 - IRG/WP 92-1558
Siderophores are iron-chelating extracellular fungal metabolites which may be involved in initiating wood decay. A purified siderophore extract isolated from the brown-rot decay fungus Gloeophyllum trabeum (Pers. ex Fr.) Murr. (Basidiomycetes: Polyporaceae) was found to deter feeding by Formosan subterranean termites, Coptotermes formosanus Shiraki (Isoptera: Rhinotermitidae). This fungus has prev...

The distribution of introduced acetyl groups and a linseed oil model substance in wood examined by microautoradiography and ESEM
2000 - IRG/WP 00-40169
Microautoradiography, a photographic method that shows the localization of substances labelled with radioactive isotope, and Environmental Scanning Electron Microscopy (ESEM) were combined to enhance sensitivity, resolution and reliability for examination of the distribution of introduced substances in wood. The preparation of microautoradiographs is less complicated when investigated with ESEM an...

Preliminary screening of diffusion formulations for the control of soft rot
1978 - IRG/WP 2104
We have an urgent need in Australia to develop in situ remedial treatments for the present population of in-service transmission poles. For various reasons we have opted for formulations which can be applied as bandage treatments and thus we are primarily concerned with assaying diffusable toxicants. Two basic approaches have been made: an assay of the formulation's toxicity; and a combin...

Mapping soft rot decay distribution using image analysis
1993 - IRG/WP 93-20011
Image analysis has been shown to be a useful technique for the assessment of soft rot decay caused by Chaetomium globosum in birch and bamboo (Wickens and Murphy, 1992). The technique can permit assessment of decay in individual or small groups of cells and this has been used to undertake soft rot decay mapping in thin sections of bamboo. Assessments were made of the extent of soft rot decay with ...

In general, the potential of high toxicity (aquatic and human) of wood protection (antisapstain) chemicals dictates the need to protect the environment and humans from its harmful effects. This document is a compendium of recommendations for the design and operating practices of wood protection facilities. The suggested recommendations focus on achieving the objectives of protecting the environmen...

In-ground evaluation of a copper azole wood preservative (Tanalithâ E) at a tropical Australian test site
1996 - IRG/WP 96-30100
A field trial to determine the in-ground termite and decay resistance of Pinus radiata D. Don impregnated with a copper azole formulation, TANALITHâ E, has been established at a tropical site in the Northern Territory of Australia. Four retentions of TANALITHâ E, containing 1.54, 2.08, 2.92 and 4.30 kg/m³ of Cu, are being evaluated. For comparison, Pinus radiata specimens treated to two retenti...
