Wood extractives as carbon sources for staining fungi in the sapwood of lodgepole pine and trembling aspen
1995 - IRG/WP 95-10098
Wood discoloration by sapstaining fungi reduces lumber value. In Canada, the most commonly recorded sapstaining fungi belong to the genera Ophiostoma. This work evaluated the effect that Ophiostoma piceae, Ophiostoma ainoae, and Ophiostoma piliferum used the lipids present in the sapwood of lodgepole pine (Pinus contorta Dougl.) and trembling aspen (Populus tremuloides Michx.). Wood lipids, common...

Further thoughts on standard principles of testing termiticides and/or wood preservatives
1992 - IRG/WP 92-1530
At the last annual meeting in Kyoto, Japan, there was a special session devoted to the standard principles of testing termiticides. There was definitely a perceived need by researchers and industry for some guidelines that spell out basic procedures required for any methodology in testing termiticidal formulations anywhere in the world. In the testing of new potential active ingredients, considera...

Étude in vitro de la colonisation et de la dégradation structurale du bois d'aubier de Pin sylvestre par la Mérule: Serpula lacrymans Schum. ex Fr. S. F. Gray
1979 - IRG/WP 198
The degradation of Scots pine sapwood cell walls by Serpula lacrymans, a brown rot fungus, is observed after various periods of exposure from two weeks to twelve weeks. The observation by microscopy shows that the hyphae of Serpula rapidly invade the wood tissues as cell wall degradation starts. That deterioration is not gradual, it is observed to be very irregular as well within the whole of the ...

Termite response to Agricultural Fiber Composites: Bagasse
2005 - IRG/WP 05-10549
Bagasse, or sugarcane rind, is a fibrous by-product of sugar extraction from sugarcane, Saccharum officinarum L. Bagasse fiber performs similarly to hardwood fiber in composite board products. In laboratory studies, Formosan subterranean termites survived as well on a diet of Bagasse as on Douglas-fir wood. Field tests with a compressed Bagasse panel (produced by heat extrusion) indicated that ter...

In service performance of wood sound abatement barriers
2024 - IRG/WP 24-41006
Sound abatement barriers made form treated hem-fir in service near Vancouver, Canada were inspected after about 10-12 years in service. The barriers appeared in good condition and no boards were to the point of needing replacement. The sound abatement decibel readings at all locations indicate they perform as well as concrete barriers and exceed the 5 dBA regulatory requirement for noise reduction...

Effect of mobile fungicides on fungal pre-infection in radiata pine billets.
1999 - IRG/WP 99-30191
In New Zealand, fungal infection of logs begins directly after felling and whilst severe degrade can be prevented if antisapstain-treated within 24 hours, such short turn-around times of logs are not always practicable. However, conventional antisapstain formulations in use only provide an envelope of protection on the log surface but are unable to control pre-infections below the surface. The obj...

A new technique for testing decay resistance of framing lumber
2002 - IRG/WP 02-20247
Model house frame units (two studs, top and bottom plates and a central “dwang”) were constructed using short (500-600 mm) lengths of framing timber. Constructed frames were impregnated with water using a mild pressure schedule to raise the initial moisture content to 35-40 % mc. The back face of each unit was then covered with black polyethylene. Two locations at the stud/dwang and stud/botto...

Efficacy of deltamethrin associated with TCMTB and MBT for the temporary protection of timbers immediately following their sawing, in tropical countries
1987 - IRG/WP 1321
K-Othrine bois 2.5 "sciage"Ò containing 2.5 g/l of deltamethrin, 50 g/l of TCMTB and 50 g/l of MBT used at a 6% dilution controls effectively during the drying process of the freshly sawn wood, the insects attacking wet wood, the staining fungi and the rots. The protection lasts 4 months. The efficacy trials carried in 1985 and 1986 in the CTFT ("Centre Technique Forestier Tropical") of Abidjan, ...

Moisture requirements and wood degradation of pine and spruce wood by some Basidiomycetes-fungi
1989 - IRG/WP 1406
The minimum moisture requirements for the growth of the brown rot fungi, Coniophora puteana, Gloeophyllum trabeum and Serpula lacrymans were near or above the fibre saturation point of pine and spruce, sap and heartwood, during 160 days incubation according to the standard method EN 113. The moisture of wood for the optimum growth of Coniophora puteana and Serpula lacrymans was about 35-80% and fo...

Treatability problems - Relationships between anatomy, chemical composition and treatability
2001 - IRG/WP 01-40213
This report documents the results of phase 1 and 2 of a 3-phase research program. In phase 1, two hundred and fifty-six (256) Southern pine (pinus spp.) nominal 2 x 6's (38 mm x 140 mm) from a single mill in Georgia (southeastern US) were evaluated for treatability with CCA preservative. After treatment, 128 pieces representing a broad range of treatment characteristics were selected and ...
