Studies on the infestation behaviour of the powder-post beetle Lyctus brunneus (Steph.) and its physical control in the wood yards of the Caspian forests of Iran
1985 - IRG/WP 1271
Lyctus brunneus (Steph.) is a pest which has not been previously thoroughly studied in Iran. It severely attacks Iranian hardwoods, especially those used in wooden houses and that have not been treated. Research work was necessary to determine the natural resistance of the most important timber species in Iran against this insect....

Inventory of the use of preservative-treated wood and wood preservatives in Sweden 1900-1997
1999 - IRG/WP 99-50137
The objective of this study was to present an overview of the use of wood preservatives and their active ingredients and industrially preservative-treated wood in Sweden since the beginning of the 20th century. The data presented in the report could for example be used as a basis for different waste management scenarios for preservative-treated wood. Before 1960 railway sleepers and utility poles ...

Short-term field test method with accelerated infection of Basidiomycetes in wood
1981 - IRG/WP 2155
In the ŠIPAD - IRC Wood Protection Laboratory an attempt has been made to develop a simple short-term method for field testing out-of-ground contact wood using accelerated infections with Basidiomycetes. This method makes it possible to obtain a preliminary assessment of a preservative's quality and to estimate the possibility of achieving promising results in more expensive long-term te...

Eco-tax - A new threat for wood preservation? The Belgian experience
1993 - IRG/WP 93-50001-32
At the end of January 1993, a bill was put for Belgian Parliament related to the introduction called "Eco-taxes" on a series of products, such as packaging for drinks (especially on PVC-bottles), non-returnable articles (shavers, small cameras), batteries, pesticides for non-agricultural use and paper....

Tebuconazole, a new wood-preserving fungicide
1990 - IRG/WP 3634
TEBUCONAZOLE, an anti-fungal triazole compound, has been tested to assess the effectivness as wood preserving fungicide. Tests were made with the active ingredient and also in formulations against basidiomycetes, blue-staining fungi and mould. Results of the DESOWAG laboratories and also from official institutes will be presented. In addition to this there were made different toxicological and eco...

Decay resistance of wood removed from poles treated with Trichoderma
1989 - IRG/WP 1386
Wood blocks removed from a distribution pole previously treated with a biological control product (Binab FYT pellets) were exposed in soil block tests to selected basidiomycetes. The blocks were removed from regions of poles where Trichoderma colonization had been confirmed by extensive sampling and computer mapping of microbial inhabitants. The results indicate that material from pole interiors c...

Comparative investigations on the influence of wood seasoning, wood properties and temperature on the toxic values of wood preservatives against Hylotrupes egg larvae
1970 - IRG/WP 28
Comparative tests carried out at three institutes indicated the influence of kiln temperature, position of wood specimens in the cross sectional area and test temperature on the toxic values determined in accordance with DIN 52165 with egg larvae of the house longhorn beetle (Hylotrupes bajulus L.). The preservatives applied were boric acid in distilled water and g-benzene-hexachloride dissolved i...

Biological Durability of Laminated Veneer Lumber from Durable and Non-Durable Wood Species
2005 - IRG/WP 05-10567
Laminated Veneer Lumber (LVL) was laboratory manufactured using veneers from decay and non decay resistant species in order to evaluate changes in the durability as a result of the LVL manufacturing process, and to test if the mixing of decay resistant species and non decay resistant species can improve durability. Laboratory soil block test and field test were conducted. The durability of solid w...

Establishment of a laboratory method to characterise the ecotoxicity of a polluted soil
1998 - IRG/WP 98-50101-23
This method consists in using the underground grub of the Oxythyrea funesta beetle as a bioindicator of the soils pollution.
Due to the significant tolerance of the organism, a large type of substrate of different nature and grain size could have been studied.
We have tested substances and preparations such as wood preservation products even under powder or liquid form but also some wastes of di...

New technique for inoculation of wood wafers with fungi
1997 - IRG/WP 97-20113
A pilot study is described for determining the best possible method for inoculating fungi onto the surface of wood wafers for sapstain control studies. Direct inoculation and spray inoculation are compared on water soaked and malt extract broth soaked wood wafers. The best growth of fungal hyphae across the surface of the wood wafers was achieved following spray inoculation onto malt extract broth...

Dimensional stabilization of wood with dimethylol compounds
1987 - IRG/WP 3412
This study showed that a substantial degree of dimensional stability can be imparted to wood by crosslinking with low concentrations of dimethyloldihydroxyethyleneurea. It was demonstrated that by selecting the right catalyst system the cure temperature can be reduced to the point that strength loss of the treated wood is minimized....

Blue stain in service on wood surface coatings. Part 2: The ability of Aureobasidium pullulans to penetrate wood surface coatings
1992 - IRG/WP 92-1557
The ability of Aureobasidium pullulans to penetrate seven different wood surface coatings was examined. Eight isolates of Aureobasidium pullulans were used. Following penetration, light microscopy was used to examine the effect of the fungus upon the coating, and growth at the wood-film interface. The fungus showed different growth capabilities with different types of surface coatings. Some isolat...

Studies of the distribution and degradation of tributyltin naphthenate in double-vacuum treated wood
1983 - IRG/WP 3230
The effects of forced solvent evaporation by kilning redwood (Pinus sylvestris) that has been double-vacuum treated with tributyltin naphthenate (TBTN) have been investigated. Contrary to previous studies reported, it has been shown that forced evaporation can have a considerable influence on the losses of the fungicide. It has been found that, whether the solvent is allowed to evaporate slowly or...

Rates of emission from CCA-treated wood in the marine environment: measurement, modelling and requirements for further research
2001 - IRG/WP 01-50166-12
Accurate estimates of rates of emission of leachate from preservative treated wood are crucial for realistic predictions of the environmental impact of its use in maritime construction. Estimates are available for some commonly used preservatives, but these vary widely. Though variable, these measurements suggest that emission generally decreases exponentially with time. Part of the variation is d...

Wood-destroying insects found in the Eastern Black Sea sub-region of Turkey
1982 - IRG/WP 1153
The Eastern Black Sea subregion has important forest resources. The settlement areas are scattered at the countryside. That's why a good deal of wood and timber is used in the construction of buildings without sufficient protective measures in the rural areas. In the forests and rural buildings 52 wood-destroying insect species have been specified 35 of which are new in this subregion and...

Update on lab and field test results for polymeric alkylphenol polysulfide treated wood
2002 - IRG/WP 02-40240
The possibility of using Polymeric Alkylphenol Polysulfide (PXTS) as a wood preservative has been undergoing evaluation in our laboratories for the past four years. Various formulations prepared from this compound have been tested and found to be effective against wood decay fungi and insects in field stakes after 42 months exposure. In accelerated soil bed tests, PXTS has been shown to be consi...
