Synergistic effect of the association of Prosopis juliflora polyphenolic extractives with tebuconazole on the growth inhibition of brown and white rot fungi: a solution to increase the naturality and safety of wood preservation treatment
2025 - IRG/WP 25-20732
The antifungal effect of catechin and extractives from Prosopis juliflora was studied against one white rot fungus, Trametes versicolor (TV), and one brown rot fungus, Rhodonia placenta (PP). The extractives from Prosopis julilfora were crude mesquitol and pure mesquitol. Tebuconazole was used in this study as a known fungicide against the two named fungi. Wood protection using fungicides can be h...

Potential co-valorization of pyrolysis tars from five wood species form Tunisia as wood preservatives bases: Chemical compositions, antifungal and anti-termite activities
2025 - IRG/WP 25-20739
The pyrolysis of five Tunisian wood species (Ceratonia siliqua, Eucalyptus camaldulensis, Eucalyptus maidenii, Pinus pinea, and Quercus canariensis) was carried out in a custom-designed carbonisation reactor developed at the INRGREF's Wood Technology Section (Tunis, Tunisia). This process aimed to produce both char and pyrolysis by-products, particularly pyrolysis oils. The experiments were conduc...

Influence of plasma treatment on the coatability of wood primer with a topcoat for exterior use
2025 - IRG/WP 25-30828
The coatability of oil, or of solvent-borne alkyd resin wood primers with waterborne acrylic finish is the subject of much debate, but not much information can be found in the scientific literature on this topic. The aim of our study was therefore to evaluate the adhesion strength of the waterborne acrylic coating on oiled wood or wood with a solvent-based alkyd primer and to test the recoatabilit...

Recycling wood treated with copper-based preservatives to produce hard carbon materials for energy storage applications
2025 - IRG/WP 25-50401
In this study, we explored the possibility of recycling wood treated with copper-based preservatives to produce hard carbon materials for use in energy storage devices. We pyrolsed both untreated and copper-treated wood into hard carbon, conducted microstructural and physicochemical characterisation, prepared electrode materials, and evaluated their electrochemical performance in sodium-ion batter...

Bio-Based but Toxic? The Neglected Ecotoxicity of Leachates from Wood Preservatives—A mini-review
2025 - IRG/WP 25-50403
Bio-based Wood preservatives, derived from renewable biomass, are emerging as promising alternatives to traditional synthetic wood preservatives. Research groups all around the world are studying the development of bio-based – environmentally friendly – wood preservatives and their fixation to wood finding natural compounds with very promising wood preserving potential. However, there is a ver...

Confocal laser scanning microscopy of a novel decay in preservative treated radiata pine in wet acidic soils
1997 - IRG/WP 97-10215
Light microscopy of radiata pine (Pinus radiata D. Don) field test stakes (20x20x500mm3) exposed in wet acidic (pH 3-4) soil for 12 - 24 months showed predominance of an unusual type of decay characte-rised by tunnelling attack of wood cell walls. After two years decay was moderate to severe in wood treated to ground contact CCA specifications and also equivalent retentions of creosote, and a numb...

Effect of acetylation on decay resistance of wood against brown-rot, white-rot and soft-rot fungi
1989 - IRG/WP 3540
Effect of acetylation on decay resistance of wood was investigated using wood blocks of Cryptomeria japonica, Pinus densiflora, Albizia falcata and Fagus crenata. Blocks were treated with uncatalyzed acetic anhydride for different lengths of time and exposed to Tyromyces palustris, Serpula lacrymans, Coriolus versicolor and unsterilized soil. The action of OH-radical on acetylated wood was also ex...

JWPA method for testing effectiveness of surface coatings with preservatives against decay fungi
1981 - IRG/WP 2164
In 1979 JWPA established a new method for testing effectiveness of surface coatings in accordance with practical use of preservative-treated lumber. Comparing the new testing method with JIS A 9302, a few new trials - size of wood specimen, weathering procedure, and decay-test procedure - are incorporated....

Biological screening assays of wood samples treated with creosote plus chemical additives exposed to Limnoria tripunctata
1980 - IRG/WP 408
Laboratory methods for exposure of treated wood coupons to Limnoria tripunctata are described. Chemical additions to creosote were screened using this method. Three pesticides, Endrin, Kepone, and Malathion proved particularly effective. The addition of varying percentages of naphthalene to creosote using several treatment methods are currently being assayed. Results to date show that the coupons ...

Proposed method for out-of-ground contact trials of exterior joinery protection systems
1981 - IRG/WP 2157
Methods for testing the efficacy of preservative treatments for exterior joinery are described using the format of a European Standard. Commercially used treatments applied to jointed test units (L-joints) which are then protected by conventional finishes are exposed to normal outdoor hazards out of ground contact. Assessment is made a) by determining eventual failure through decay and b) by destr...

Screening potential preservatives against stain and mould fungi on pine timber in Zimbabwe
1995 - IRG/WP 95-30063
The search for environmentally and toxicologically safer chemicals for use in the timber preservative industry against stain and mould fungi has been intensified during the past few years. Results of field tests with two chemicals previously evaluated in the laboratory are presented. The conventional sodium pentachlorophenate was the more efficacious chemical against stain and mould fungi, providi...

Sequestration of copper ions by the extracellular mucilaginous material (ECMM) of two wood rotting basidiomycetes
2004 - IRG/WP 04-10533
The radial growth rate of colonies originating from either whole or ECMM-free inocula of Coriolus versicolor was investigated. The presence of ECMM allowed colonies to maintain higher growth rates than those form ECMM-free inocula up to 2 mM CuSO4 in the medium. The ECMM of C. versicolor and G. trabeum was able to reduce the diffusion of copper ions in solution. The ‘raw’ ECMM of both fungi ha...

Improvements of monitoring the effects of soil organisms on wood in fungal cellar tests
1996 - IRG/WP 96-20093
Accelerated testing the durability of preservative treated timber in a so called "fungal cellar" or "soil-bed" to evaluate its performance in ground contact is widespread practice. In order to obtain a more accurate and reproducible estimate of preservative performance, several institutes, among them the BAM in Berlin, have routinely carried out static bending tests in addition to visual examinati...

Aspects of diffusion of boron through wood
1984 - IRG/WP 3298
Boron compounds have been shown to be toxic to a wide range of wood destroying insects and fungi. They are cheap, have low mammalian toxicity and their application in the treatment of wood does not demand specialized equipment. These attributes make them specially attractive to developing countries. Currently, however, little is known about the mechanism of diffusion of boron through wood. Effecti...

Analysis of tebuconazole in wood treated with Tanalith™ E
1999 - IRG/WP 99-20158
A simple gas chromatographic method for determining tebuconazole in Tanalith™ E treated wood is described. A two step sequential extraction procedure with methanol was used. Sample extracts were analysed without cleanup or concentration using capillary column GC with thermionic specific detection. The performance of the method was assessed using radiata pine (Pinus radiata) sapwood, radiata pine...

The applicability of life cyle analysis and alternative methods in the wood preservation industry
1994 - IRG/WP 94-50023
In the Netherlands, several case studies have been performed using the life cycle analysis method (LCA). This type of research is aimed at an inventory and classification (sometimes including also evaluation) of the environmental impacts of a product, from the raw material to waste stage ("cradle to grave" approach). In a LCA each environmental impact is assessed in terms of, for example, mass of ...
