The yeast Pichia sp. As a short-term biological control agent to fungal spoilage of sawn softwood timber
2000 - IRG/WP 00-10362
Previous work has found isolates of the yeast Pichia to be a successful biological control agent toward moulding of fruits. An isolate was tested for the ability to protect sapwood of Pinus sylvestris timber against visual degrade by surface growth of moulds and staining fungi. Successful protection of autoclaved wood sprayed with a mixture of common wood moulding fungi was achieved when the yeast...

Eastern subterranean termite responses to three soil pesticides
1990 - IRG/WP 1432
In laboratory assays simulating field conditions, tunneling and mortality of Reticulitermes flavipes (Kollar) workers were evaluated in sand treated with aqueous solutions of formulated chlorpyrifos, isofenphos, and disodium octaborate tetrahydrate. Chlopyrifos and isofenphos were evaluated at concentrations of 500 and 1000 ppm (weight of active ingredient / weight of sand), and disodium octaborat...

Susceptibility testing protocol for powderpost beetles in Australia
2002 - IRG/WP 02-20242
Several species of lyctine (powderpost) beetle are able to attack a range of hardwood timbers in Australia. Powderpost beetles infest only the starch-containing sapwood of certain
hardwoods and do not infest softwoods. Attack by powderpost beetles on susceptible timber in Australia is almost inevitable and may continue until the food resource is completely utilised. Prevention of powderpost beetl...

Protecting wooden structures
1980 - IRG/WP 392
Chromium-containing chemicals that effectively retard weathering of wood improve performance of subsequently applied finishes. Current work is focusing on the performance of wood-derived products (plywood, hardboard, fiberboard, particle board) after surface treatment with inorganic chemicals. The overall objective of the continuing research is to investigate new environmentally safe procedures to...

Changes to New Zealand Timber Treatment Specifications
2004 - IRG/WP 04-20288
Changes have been made to the New Zealand timber treatment specifications in response to frequent incidences of decay in framing timber and doubts about the long-term performance of tributyltin formulations when used in exposed situations.
Changes have been made to Hazard Class H1 to allow a level of treatment to provide short to medium decay resistance to framing which would protect it, should l...

Testing method for the treatability of wood
1994 - IRG/WP 94-40031
In order to test and classify the treatability of wood species in pressure treatment processes with water-based solutions, a laboratory method was developed which allows the testing of small samples and limited sections of a stem, e.g. sapwood. The penetration of different liquids was determined separately concerning the three anatomical directions of wood. The common parameters for pressure impre...

Effects of terpene compounds on the growth and peroxidase activity of Phellinus pini
1979 - IRG/WP 2130
The volatile compounds myrcene, limonene, a-pinene, a-terpineol, D-fenchol and 1,8-cineole, present in the oleoresin fraction of coniferous wood, were tested individually and as mixtures for their effect on the growth and peroxidase activity of cultures of six strains of Phellinus pini (Fr.) A.Ames and one strain of Phellinus chrysoloma (Fr.) Donk (Phellinus pini var. abietis (Karst.) Pilát). Phe...

Waste management of wood products in life cycle assessment
2000 - IRG/WP 00-50154
Within the framework of the European project LIFE SYS WOOD (contractnr. FAIR CT95-7026) TNO has performed a study on the waste management of wood demolition waste for inclusion in Life Cycle Assessment. In LIFE SYS WOOD one of the main aims was to develop a consistent LCA methodology for wood products. LCA case studies have been performed by partners on wood as raw material, glulam contructions, O...

Soft rot decay of 23 CCA-treated hardwoods from Sabah, Malaysia, in ground contact in Australia
1986 - IRG/WP 1280
The performance against soft rot decay of 23 CCA-treated hardwoods from Sabah, Malaysia, was examined after 20 months in ground contact at Pennant Hills, Australia. The results indicate that between these species soft rot decay is excluded by different levels of CCA salt suggesting that the threshold level for exclusion of soft rot in these hardwoods is a function of anatomical structure/ultrastru...
