Database of sapstain fungi affecting lumber, logs and trees
2004 - IRG/WP 04-10534
Sapstain fungi discolour lumber, logs and tree sapwood and are often mistaken for moulds, which cause a superficial discoloration. Stained wood has a lower market value. Further, because stained wood products can potentially carry pathogenic fungi, such products may be refused by importing countries. Addressing these issues involves developing ways for accurately identifying staining fungi, docume...

Development and Implementation of a DNA – RFLP Database for Wood Decay and Wood Associated Fungi
2004 - IRG/WP 04-10527
We are developing Restriction Fragment Length Polymorphism (RFLP) and Internal Transcribed Spacer (ITS) sequence databases for wood decay basidiomycetes and other fungi associated with wood. These databases currently house information for 39 fungal species consisting of 9 brown-rot basidiomycetes, 12 white rot basidiomycetes, 1 soft rot, 1 stain fungi, and 16 molds or other ascomycetes or imperfe...

Performance of water-borne pressure treated fence posts - A practical application of the new Canadian field test data base
1988 - IRG/WP 2305
50 years of test plot data acquisition have been recently set up as a computerized database. The new database which contains information on the service life of a great number of non durable Eastern Canadian wood species treated with various preservatives and many application processes is presented. As an example for its use, a summary of the performance of fence posts treated with waterborne prese...

Construction of an ITS sequence database for the identification and classification of wood rot fungi
2007 - IRG/WP 07-10626
Developing a database that contains information about wood rot fungi is important in improving technologies about wood preservation as well as advances in understanding wood decay. On the other hand, with rapid spread of the Internet, establishment of a system for the swift precise access to information are required for the computerization of the research information. In the present study, genetic...

Practice Makes Perfect: A Biodeterioration Diagnostics Database that Makes Practice
2008 - IRG/WP 08-10648
Replacement of bio-based materials deteriorated by pests costs billions annually and wastes natural resources. Wood replacement rates have remained relatively stable despite significant advances in wood preservation. This may be explained, in part, by poor end-use by uninformed users and by inadequate pest management once products are in service. This problem may be exacerbated by two opposing fac...

Natural durability of African Padauk and Niove. Comparison of new trials and former data from the CIRAD database
2010 - IRG/WP 10-10743
African Padauk (Pterocarpus soyauxii) and Niove (Staudia kamerunensis) were tested in laboratory against Basidiomycetes. The results were calculated according to the requirements of EN 350-1 (1994) and XP CEN/TS 15083-1 (2006). Padauk samples showed a high durability and very small variations between trees and within tree. Niove presented a high durability, but with notable differences according ...

Durability of timber products – Part 2: Proposal for an IRGWP - Durability Database
2012 - IRG/WP 12-20497
A proposal for a web-based platform for scientific exchange of test data in the field of wood durability and wood protection has been made. The overall aim of the durability data base is to improve the usability of existing test data and to create an added value for durability research and service life prediction. The database allows for test results from standardized and non-standardized laborat...
