An approach to testing the preventive effectiveness of preservative treatments for wooden joinery
1981 - IRG/WP 2156
The ecological sequence established in field trial samples exposed out of ground contact has shown the need for outdoor exposure in testing potential joinery preservative pretreatments. A system of exposure of L-joint units is proposed. Data obtained by examining samples destructively show promise as the basis for predicting service life after relatively short exposure periods (within 2 years)....

Changed susceptibility of the chemically and thermally degraded spruce wood to its attack by the dry rot fungus Serpula lacrymans
1999 - IRG/WP 99-10322
In buildings, some intentional or unintended situations can occur at which some wood products are exposed to aggressive chemicals and also to higher temperatures. Occasional activity of fungi on such pre-attacked wood products can be either higher or lower. This paper deals with changes in the susceptibility of spruce wood (Picea abies L. Karst.) to attack by the dry rot fungus Serpula lacrymans, ...

Description of the damage produced by xilophagus Curculionides in Spain
1989 - IRG/WP 1408
Cossoninae are a reduced subfamily of Curculionidae. These xilophagus insects produce significant damage in Spain, mainly affecting old buildings. Their activity is a real problem for the preservation of the country's historical-artistic heritage. The three Cossoninae species most widespread in Spain are described for the first time as well as the conditions under which they develop. The ...

The effect of storage or simulated internal use on the durability of wood based panels to decay fungi
1997 - IRG/WP 97-20106
Wood based panels such as particleboard and medium density fibreboard are experiencing a steady increase in use, in areas from structural to decorative applications. Understanding the "natural" durability of these panel products against basidiomycete fungal decay is therefore of great importance. Various methods have been proposed or are under development to test the durability/susceptibility of v...

Biological control of decay in standing creosote-treated poles
1976 - IRG/WP 156
Internal decay caused by basidiomycetes in standing creosoted poles can be controlled biologically, it seems, by artificial inoculation near the ground line. For such inoculation IC-type facultative mycoparasites, Scytalidium sp FY strain or Trichoderma spp for example, may be used. Apparent residual action can be explained by the release of non water soluble chemically stable antibiotics from the...

A preliminary report on lignicolous marine fungi in the Java Sea, Indonesia
1982 - IRG/WP 488
This report is part of a study on the natural durability of Indonesian timbers against marine borers conducted in Pari Island waters, Java Sea (Suhirman and Eaton, 1981), and contains preliminary information which has not yet been published....

Accelerated wood decay in a soil bed test under greenhouse conditions compared with a stake test under field condition
1991 - IRG/WP 2384
The rate of decay of oak, beech, Douglas fir, pine and spruce stakes in an outside test field were compared with the decay rate of the same species in a greenhouse soil-bed test. Strength loss after four and six months respectively was measured by determining the compression strength parallel to the grain. The results show that all species, strength loss in the greenhouse was 2 to 4 times higher t...

Wood preservation in the Australian beekeeping industry
1988 - IRG/WP 3473
This paper reports the results of a survey of Australian commercial beekeepers working 200 or more hives in June/July 1985. Nine hundred and forty seven apiarists were asked to participate and to provide information on their wood preservation methods, painting procedures and maintenance of bee boxes. Three hundred and eighty-four apiarists returned completed questionnaires (41%). The main wood pre...

Localization of oxalate decarboxylase in the brown-rot fungus Postia placenta
1996 - IRG/WP 96-10161
Oxalate decarboxylase, the enzyme that breaks oxalic acid down into formic acid and carbon dioxide, was recently detected in mycelial extracts of the brown-rot fungus Postia placenta. Differential centrifugation was used to demonstrate that the enzyme is loosely associated with the hyphal surface. Enzyme activity can be removed by washing the hyphae with a low pH buffer. Only low levels of activit...

Effect of sterilization method on germination of spores of wood decay fungi observed by contact agar block method
1978 - IRG/WP 2117
Previous studies of germination of spores of wood decay fungi on wood have generally concluded that method of wood sterilization has little significant effect on germination response. This study expands the numbers of test fungi as well as number of sterilization methods employed to determine the influence of sterilization method on spore germination response of decay fungi. Germination was assess...

Proposals for collaborative work on laboratory soft rot testing
1986 - IRG/WP 2265
Proposals for collaborative experiments based on soil burial are presented. It is intended to study the use of defined horticultural loams with a view to obtaining more reproducability in laboratory soft rot tests....

Comparison of decay rates of preservative-treated stakes in field and fungus cellar tests
1980 - IRG/WP 2135
With the exception of acid-copper-chromate, zinc-chrome-arsenate, and sodium pentachlorophenoxide, the relative performance of preservatives in the fungus cellar was similar to that in the field....

A new approach to the maintenance of wooden railway sleepers. (Second report)
1988 - IRG/WP 3492
The microenvironment and micro-ecology of wooden railway sleepers was investigated to assess their condition to determine the necessary treatment, repair and replacement criteria. In this report the efficacy of the secondary preservative treatment with solid boron rods is discussed and the development of an in-situ, nondestructive test method based on the creation and assessment of structural dyna...

Combined effects of the treatment of wood with formaldehyde
1978 - IRG/WP 3117
Treatment of fibrous materials with reagents in a vapor phase is neither new nor unique. Numerous examples exist in literature of vapor phase experiments on cellulose fibers and fabrics, and on wood. For many years the textile research and industry have used vapor phase processes for the treatment of textiles. The chemical modification of cellulose is based on different types of reactions e.g. est...

Collaborative soft rot test: Amended test method
1972 - IRG/WP 208
The initial draft of a standard test method (Document IRG/WP/201) was discussed at the meeting in Brussels in 1971. It was agreed that a revised draft should be prepared and that the Princes Risborough Laboratory (formerly FPRL) should conduct a trial test using the method as a preliminary to the main collaborative test....

Conditions for basidiospore production in the brown rot fungus Gloeophyllum separium in axenic culture
1984 - IRG/WP 1232
Attempts to control and optimize the production of hymenial structures and basidiospore production in Gloeophyllum sepiarium in axenic culture resulted in the proposal of the following conditions as being suitable. The dikaryotic mycelia originally isolated from basidiocarps could consistently be induced to produce hymenial structures and pure basidiospore collects if illuminated by near ultraviol...

The performance of wood preservatives in soil-bed soft rot tests
1993 - IRG/WP 93-20007
Testing the efficacy of wood preservatives in soil is recognised as a fundamental part of the assessment of long-term wood protection in ground contact. Laboratory based tests can provide a hazardous environment in which a preservative can be challenged by a range of micro-organisms. This paper presents the results of tests carried out to investigate the performance of wood preservatives in a wet ...

A laboratory soil-block decay evaluation of plywoods edge-treated with preservatives
1982 - IRG/WP 2174
Preservative-treated plywood used under conditions or severe decay hazard frequently has its original, or cut edges, protected by the application of a field-cut preservative. This study uses a laboratory test method to compare the efficacy of four commercial preservative treatments against two commonly occurring brown-rot fungi. The results are not meant to indicate the service life of such treate...
