Austrian field test method for anti-sapstain chemicals
1994 - IRG/WP 94-20020
Although Austria is a small country, the annual consumption of anti-sapstain products ranks to approximately 500 tons annually. In 1994, only three products will be approved by the Austrian Wood Preservation Committee (AWPEC). There is demand for a field test method, which demonstrates the efficacy of an anti-sapstain product and consequently implies the acceptance and approval of product by the A...

Exterior weathering trials on radiata pine roofing shingles
1985 - IRG/WP 3240
A series of test roofs clad with radiata pine (Pinus radiata D. Don) shingles that had been pressure-treated with various water-borne preservative formulations were installed at a Forest Research Institute test site in Rotorua in 1977. A further series of test roofs installed in 1978 included radiata pine shingles pressure-treated with a commercial light organic solvent preservative (LOSP). Evalua...

Collaborative experiments in testing the toxicity of wood preservatives to soft rot fungi
1970 - IRG/WP 25
Eight Institutes from seven countries, Austria, England, France, Germany, Holland, Sweden and Switzerland have collaborated in an attempt to assess the suitability of various laboratory test procedures for acceptance as standard methods of determining the toxicity of wood preservatives to the cellulose-attacking micro-fungi which cause 'soft rot' of wood. Pure culture methods wit...

Relationship between stacking, location and antisapstain preservatives on visible degrade of Eucalyptus regnans and Pinus radiata boards
1999 - IRG/WP 99-20162
An antisapstain trial was established at a Eucalyptus hardwood sawmill in Victoria, Australia. The trial incorporated two commercial formulations of antisapstain preservatives, used at four different concentrations on both hardwood (Eucalyptus regnans F. Muell) and softwood (Pinus radiata D. Don) boards. The trial also utilised different stacking methods (block-stacked, sticker-stacked, and block-...

Baiting techniques for subterranean termite control
1983 - IRG/WP 1205
The use of artificial baits, with and without toxins, have proved effective in attracting large numbers of non-mound and mound building subterranean termites in both urban and rural areas. An outline is presented of a termite baiting program which emphasises concurrent laboratory and field investigations on termite ecology, behaviour and physiology...

Comparative performance of pentachlorophenol and copper naphthenate in a long term field stake test
2000 - IRG/WP 00-30243
In this study the performance of copper naphthenate (Cu-Nap) and pentachlorophenol (Penta) treated pine stakes against decay and termite attack were compared at two test sites in Mississippi. Four different petroleum oils meeting AWPA Standard P9-A were used as carriers for these wood preservatives. After ten years exposure, the efficacy of Cu-Nap at a retention level of 0.05 pcf Cu was equivalent...

Moulds and indoor climate in Denmark
2003 - IRG/WP 03-10488
Just like in many other countries after the oil crisis in 1972 Danish houses were tightened with the result that the relative air humidity rose considerably. The Ministry of Energy also demanded a lowering of the indoor temperature from 25°C to 20°C with the result that the relative air humidity rose even more. According to the latest survey 10% of Danish buildings are infected with moulds. Moul...

Decay patterns observed in butylene oxide modified ponderosa pine attacked by Fomitopsis pinicola
1983 - IRG/WP 1183
Small blocks of ponderosa pine chemically modified by butylene oxide to three different weight percent gains (WPG) were decayed for 2 months with the brown rot fungus Fomitopsis pinicola. Wood substance loss and the type of decay pattern recognised were fairly similar both for control and blocks treated to 8 and 15 WPG. No difference in attack was observed between radial or tangential walls in lat...

Ecotoxicological risks of anti-sapstain preservatives washed off from treated timber
2000 - IRG/WP 00-50144
A field method for ecotoxicity assessment of rain water wash-off from anti-sapstain treated timber was developed. In the course of this study freshly sawn timber treated with 1.5% Busan 30 L (reference preservative) and a control stack with untreated pine were exposed to weathering. The run-off water was ecotoxicologically tested with organisms from three trophic levels (Vibrio fischeri, Kirchneri...

Short term preconditioning of preservative-treated wood in soil contact in relation to performance in field trials
2000 - IRG/WP 00-20185
The effect of pre-exposure to primary colonising micro-organisms on preservative-treated wood, prior to a basidiomycete decay test, was determined by preconditioning in two soil types. Scots pine EN 113 blocks treated with 3 model systems (a triazole, a copper quaternary compound and a copper boron triazole) were leached according to EN 84 and subjected to 6 weeks and 8 weeks burial in either John...

Tentative method of testing wood preservatives against blue staining
1977 - IRG/WP 259
The blue stain of sawn wood is still a real problem in Poland. Although a preservative based on sodium orthophenylphenoxide has been introduced into sawmill practice, and the technology of wood protection developed with it, new information has been obtained concerning blue stain in wood material destined for export. In order to select new chemicals or to improve the effectiveness of the ones in cu...

Sequential exposure of borate treated Douglas-fir to multiple Formosan subterranean termite colonies in a 40-week field test
1993 - IRG/WP 93-10006
Douglas-fir boards (ca. 74.5 g) pressure-treated with disodium octaborate tetrahydrate (DOT) retentions of 0 (controls), 0.88, 1.23, 1.60, or 2.10% (weight/weight) DOT were sequentially exposed to four active field colonies of Formosan subterranean termites, Coptotermes formosanus Shiraki (Isoptera: Rhinotermitidae), in an above-ground field test. Samples were placed in contact with each colony fo...

Virulence testing of cultures of different origins of the test fungus Coriolus versicolor strain CTB 863 A
1986 - IRG/WP 2267
The virulence of cultures of different origins of Coriolus versicolor CTB 863 A - a strain which is mentioned in EN 113 - was tested. Standard blocks of beech wood were used at temperatures of 20-22°C and 26-28°C and particleboard was tested at 26-28°C. The decay capacity of the different inoculations varied widely, as could be expected it was greatest at the higher temperature level....

Natural durability and basic physical and mechanical properties of secondary commercially less accepted wood species from Brazil
2002 - IRG/WP 02-10451
The natural durability towards basidiomycete fungi and termites of several secondary timber from Brazil (Vatairea sp., Hymenolobium sp., Inga sp., Manilkara sp., Caryocar sp., Terminalia sp., Apuleia sp.) has been evaluated according to the EN 350-1. Some basic physical and mechanical properties (density, shrinkage, hardness, colour, static strength in flexion and compression) were also measured a...

Some wood-destroying Basidiomycetes. Volume 1 of a collection of monographs
1981 - IRG/WP 1121
One of the first tasks of the International Research Group on Wood Preservation, when it began its work in 1969, was to compile a series of reports on the common decay fungi which can attack wood. This volume, which contains the first of these reports, has been compiled with the help of mycologists and wood preservation specialists in France, Ghana, the Federal Republic of Germany, the Netherlands...
