The Effect of Soil on the pH of Untreated Southern Pine in Ground Contact
2010 - IRG/WP 10-10742
Untreated southern yellow pine samples were subjected to three soils that had been amended to provide acidic, neutral and alkaline conditions. Wood pH was measured prior to, and then one, two, four and eight weeks after being placed in the soil to determine the effect of soil pH on wood pH....

Accreditation: mutual benefits for research and industry
2010 - IRG/WP 10-20452
The wood preservation laboratory of the CIRAD had its first ISO 17025 accreditation from the COFRAC in 2006 for 5 standardized test procedures. The so called “first cycle” of its accreditation will be mid-2010. This laboratory is now accredited for 8 tests and is planning to increase the field of its quality management and accreditation. This poster describes how research projects, pre-normati...

Situation of Wood Protection in Spain
2010 - IRG/WP 10-40511
This paper shows the actual situation of Spanish Wood Protection. In the evolution of this sector over the last years, three factors have been very important: the increase of the use of wood for both structural and decorative uses in construction, the development of the Technical Building Code, and the transposition and implantation of the Directive of Biocides to Spain in October 2002....

Quality assurance approach of the German TMT manufacturers
2010 - IRG/WP 10-40513
Due to an increasing number of TMT manufacturers in central Europe, an organisation of TMT manufacturers was founded in Germany in the beginning of 2010. Since the current level of product testing and property declaration is not satisfying, one of the first activities is the establishment of a quality assurance system. In this paper a concept for quality assurance (QA) will be outlined....

Non Toxic Remedial Treatment of Bamboo Structures/Furniture
2010 - IRG/WP 10-40516
Molds and beetles often attack bamboo furniture and structures when used in untreated or inadequate preservative treatment. Remediation or eradication of infestation often involves expensive chemicals (fumigants) and specialized methods, which are not available in villages. Novel inexpensive methods using easily available chemicals were developed for controlling such infestations. Whereas applicat...
Building With Wood an strategic action in Spain
2010 - IRG/WP 10-40530
This paper explains the objectives and results of the “Building with Wood” project, mainly at Spanish level. As far as the wood preservation field is concerned, the present abstract also informs about the main goals of the project in this matter....

Sensitivity to Copper of Basidiospores from Copper Tolerant Fungi: Fomitopsis palustris and Oligoporus placentus
2010 - IRG/WP 10-10707
Copper continues to be an important fungicide in wood preservation. It is the primary component of the preservatives that have replaced chromated copper arsenate for treated wood in residential construction in North America. However, a co-biocide is normally needed to protect against copper tolerant organisms. Previous work has shown that the spores of at least one copper tolerant fungus, Oligopo...

The natural durability and preservative treatability of 11 bamboo species
2010 - IRG/WP 10-10708
Tests on the natural durability and preservative treatability of 11 common bamboo species were conducted. The results showed that there was a linear relation between bamboo density and its preservative retention by mass, and the preservative retention of bamboo reduced while its density increased. The test also showed that there were significant differences in the natural durability of bamboos, bu...

Observations on colony collapse in Reticulitermes flavipes (Kollar) in laboratory and field settings in Wisconsin
2010 - IRG/WP 10-10709
Parallel strategies were designed to eliminate Reticulitermes flavipes (Kollar) from a field site in Endeavor, Wisconsin and a simulated field test setup of approximately 20,000 workers in the laboratory. Indoor and outdoor colonies of R. flavipes were baited with commercial cellulose monitoring stations and rolled cardboard stations. If the commercial cellulose baits were attacked, they were repl...

Modelling hyphal growth of the bio-incising fungus Physisporinus vitreus
2010 - IRG/WP 10-10710
The white-rot fungus Physisporinus vitreus preferentially degrades the pit membranes of bordered pits in tracheids and subsequently enhances wood permeability. Thus, P. vitreus can be used to improve the uptake of wood preservatives and environmentally-benign wood modification substances. This process can be used to enhance the use and sustainability of native conifer wood species by the wood indu...

Assessment of the marine borer resistance and abrasion resistance of lesser known hardwood timber species for use in marine construction
2010 - IRG/WP 10-10711
Naturally durable species of timber are used as an alternative to preservative treated timber for marine structures, but many species have not been evaluated for their potential for use in this environment. EN 275 specifies a 5-year test period - too long a period for screening tests to be economically viable. In this study, candidate timber species were selected for testing both in the laboratory...

The invasion channels of damage fungi in bamboo lumber
2010 - IRG/WP 10-10712
The micro-agents on bamboo lumber damage are mould, stain, and decay fungi. This research is about invasion channels of bamboo lumber damage fungi by scanning electron microscope (SEM). The results showed that the conidia of mould were only accumulated on the surface of bamboo and no hyphae detected in bamboo vascular bundle, and hyphae of stain penetrated into bamboo and grew in metaxylem vessel...

Protection mechanisms of modified wood against decay by white and brown rot fungi
2010 - IRG/WP 10-10713
The resistance of beech and pine wood blocks treated with 1,3-dimethylol-4,5-dihydroxyethylene urea (DMDHEU) against T. versicolor and C. puteana increased with increasing WPG. Full protection (mass loss below 3%) was reached at WPGs of approximately 15% (beech) and 10% (pine). Metabolic activity of the fungi in the wood blocks was assessed as heat or energy production determined by isothermal mic...
