Reliability-based service life prediction methodology for assessment of water protection efficiency for coatings on wood
2003 - IRG/WP 03-20268
Assessment of water protection efficiency according to EN 927-5 has been shown to give significant differences in water absorption values for different types of coatings on wood. It is shown that the combination of EN 927-5 and an artificial weathering procedure gives more information regarding expected durability and long-term performance than a single measurement of water absorption on fresh, un...

Marine borers as wood degraders in Bangladesh and their protection
1996 - IRG/WP 96-10186
Field study on timber piles used in Bangladeshi brackish waters revealed that untreated and pentachlorophenol treated piles drastically degraded by the attack of molluscs and pholads (marine borers). Adequately CCA-C impregnated (30 kg/m³ or 6% W/W dry oxide retention) timber piles can protect the attack of molluscs. It is very difficult to protect pholads which can invade naturally very durable ...

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....

Marine borers and marine wood protection - Some answers and some outstanding questions - A comment
1990 - IRG/WP 4163
A brief description of the nature of hazards encountered in different parts of the marine environment is given. An attempt is then made to assess what were the essential findings of selected areas of research in the marine wood protection field and what still needs to be done. That is, if we are to more adequately understand what we are attempting to do in this field of study!...

Efficacy of some extractives from Pinus heartwood for protection of Pinus radiata sapwood against biodeterioration. Part 1: Fungal decay
1995 - IRG/WP 95-30072
Chemical compounds thought to contribute to the natural durability of heartwood of Pinus spp. were either chemically synthesised in the laboratory or extracted from the heartwood of Pinus elliottii or Pinus caribaea. These compounds included the stilbenes, pinosylvin and its mono- and di-methyl ethers, and the flavonoids, pinobanksin and pinocembrin. Small blocks of Pinus radiata sapwood were impr...

Surface Barriers for Protection of Culture and Heritage Wooden Objects from Insect Attack
2004 - IRG/WP 04-40286
Anoxic treatment is an environment friendly procedure for eradication of wood boring insects in wooden objects of cultural and historical heritage. However, after the anoxic treatment, wooden antiques remain susceptible to further insect attacks. Possible protection against insects could be provided by the so-called post-repression protective barriers. Potential coating materials for such barriers...

Framework document for an international code of good practices for wood preservation and wood protection (anti-sapstain) facilities
1992 - IRG/WP 92-3683
At the Kyoto meeting, the Health & Safety committee agreed to form a task force to prepare a global plan for writing a code of good practices (Code) for wood protection and preservation facilities (Doc. No. IRG/WP/3681). The Canadian document had been presented to the IRG group earlier (Doc. No. IRG/WP/3447) and similar documents were solicited from other countries for preparing a framework do...

Protection of Ochroma pyramidale from fungal decay with N,N-napthaloylhyroxylamine
1998 - IRG/WP 98-30182
Fungal decay of wood in service results in billions of dollars (U.S.) in losses annually. Recent environmental restrictions, both U.S. and international, are limiting and eliminating the use of broad-spectrum, heavy metal biocides for wood preservation. Restrictions result primarily from problems with disposal. New wood preservatives need to be developed and tested which specifically target key el...

The use of chlorothalonil for protection against mold and sapstain fungi. Part 1: Laboratory evaluation
1989 - IRG/WP 3515
Laboratory screening of chlorothalonil alone and in combination with other fungicides was conducted against six mold and sapstain fungi. The most promising treatments appear to be chlorothalonil supplemented with CCA or copper-8-quinolinolate. Field tests have been implemented....

The leachability and specificity of the biological protection of timber using Scytalidium sp. and Trichoderma spp
1986 - IRG/WP 1302
The results of field experiments, using biological control against internal decay of creosoted poles, are briefly reviewed and the evidence concerning the leachability of the antibiotics produced by these species is presented. A pure culture miniblock decay test on biological control treated pine sapwood is described and the results compared to previously published data. The protection against Len...

Correlation between a laboratory bioassay and field trial conducted to determine the termiticidal effectiveness of bifenthrin
2002 - IRG/WP 02-20248
Details are given of a laboratory bioassay and field trial undertaken to determine the termiticidal effectiveness of the synthetic pyrethroid bifenthrin, when impregnated into Pinus radiata D. Don sapwood specimens. Results show a strong correlation between the laboratory and field methods of evaluation. Protection threshold limits obtained were the same for the two test species of termite employe...

Wood preservation in Kenya
2000 - IRG/WP 00-40191
Current research on wood preservation in Kenya is mainly on the development of biological control of wood-destroying termite species, using mycoinsecticides. The major research institutions include the Kenya Agricultural Research Institute (KARI), Kenya Forestry Research Institute (KEFRI), Moi University and the International Centre for Insect Physiology (ICIPE). Training institutions include Fore...

Investigation of the fixation in wood of chromated zinc chloride and copperised chromated zinc chloride preservatives
1976 - IRG/WP 372
A biological method of evaluating the extent to which CZC and CCZC preparations are retained in wood in terms of the potential protection which they afford against destruction by Merulius lacrymans (dry rot) is given. CCZC is recommended for protection of wood under moderate leaching conditions, while the use of CZC under such conditions is not recommended....

Protection of beech veneer for fruit and vegetable boxes
1981 - IRG/WP 3176
In Yugoslavia about 50,000 m³ of low quality beech logs annually are rotary cut into veneer from which boxes are made for transporting fruit and vegetables. Because of steaming before rotary cutting, beech veneer becomes extremely sensitive to mould attack which decreases the quality and commercial value of the final product. To avoid mould attack, veneer sheets are dried to 16% moisture content ...

Less environmental impact of wood preservatives by considering the risk of attack in addition to the hazard class system
1995 - IRG/WP 95-50040-10
Hazard classes, which are standardized in Europe in EN 335, are most useful to direct chemical wood preservation towards the organisms which may attack wood in the various fields of utilisation. However, hazard only signifies the fact that an attack may occur without considering the actual risk to attack. To minimize the application of chemicals with respect of less environmental impact it is nece...

Laboratory evaluation of fipronil (a phenyl pyrazole) as a candidate termiticide in the protection of wood against the subterranean termite, Coptotermes acinaciformis (Froggatt) Rhinotermitidae
1997 - IRG/WP 97-10225
In this laboratory evaluation, radiata pine wood blocks (50 x 25 x 15 mm3) were impregnated with fipronil (a phenyl pyrazole) at various concentrations (0, 5, 10, 20, 40, 80, 100 and 200 ppm). Half the treated blocks underwent a leaching schedule for 5 days, while the remainder were unleached after treatment. Five replicates per treatment regime were presented to the test termite, Coptotermes acin...

Protection of OSB against termites by incorporation of different actives via glue line treatment
2008 - IRG/WP 08-30453
Different organic actives and zinc borate were incorporated into OSB during the manufacturing process to enhance the resistance against termites. Tests according to EN 117 revealed excellent performance of thiacloprid. Other organic actives such as permethrin might be effective when used in higher amounts. Zinc borate failed the test by far....
