Questionnaire: Facility for accelerated stake tests in unsterile soil
1981 - IRG/WP 2166
An acceptable name for this type of test facility has not yet been devised, but it has previously been referred to as a FUNGUS CELLAR or as a TROPICAL DECAY HOUSE. The attached pamphlet (What's New in Forest Research No.65) describes in broad terms the facility used for this purpose at FRI in New Zealand. Over the last two or three years several laboratories and commercial firms have inst...

Wood preservation research at the Technical University in Zvolen - Slovakia
2004 - IRG/WP 04-10538
Presented paper gives basic information about wood protection in Slovakia and research in the field of wood preservation at the Technical University in Zvolen – the Faculty of Wood Sciences and Technology. The degradation processes in wood and wooden composites caused by fungi, environmental factors and fire, the identification of these processes, the protection of wood with fungicides and ot...

Termite barriers for new construction
2000 - IRG/WP 00-10341
Subterranean termite protection in Australia has traditionally relied upon the creation of a zone of poisoned soil under and around the structure to prevent termite attack from the ground. The transition away from persistent soil poisons which began with the withdrawal of cyclodienes in 1995 provided market opportunities for innovative barrier systems. The new barrier systems currently being used ...

Notes on the resistance of tropical woods against termites
1985 - IRG/WP 1249
This paper deals with a descriptive account on the effect of experimental methods, matrix, species of termites, solid wood and wood extract on the resistance and repellency of woods against three species of termites, i.e. Cryptotermes cynocephalus Light; Coptotermes curvignathus Holmgren and Reticulitermes lucifugus (Rossi). Two methods of experiment were used, the Forced Feeding Test and the Feed...

Effect of double-vacuum and vacuum-pressure impregnation with water-borne preservatives on the dimensional characteristics of spruce
1990 - IRG/WP 3613
Air-dried planed spruce (Picea abies) samples were treated with a water-borne preservative (micro-emulsion) and one oil-borne type both containing azaconazole and deltamethrin. Each set of samples contained equal number of specimens with different growth ring orientation, heartwood content and density. In addition to the preservative retention and the penetration of a.i., the swelling of the sampl...

An approach to testing the preventive effectiveness of preservative treatments for wooden joinery
1981 - IRG/WP 2156
The ecological sequence established in field trial samples exposed out of ground contact has shown the need for outdoor exposure in testing potential joinery preservative pretreatments. A system of exposure of L-joint units is proposed. Data obtained by examining samples destructively show promise as the basis for predicting service life after relatively short exposure periods (within 2 years)....

Evaluation of a solid remedial wood preservative containing boron and fluorine
1993 - IRG/WP 93-30022
The fungicidal and termiticidal effectiveness of a new rod form of diffusible remedial wood preservative, containing disodium octaborate tetrahydrate/sodium fluoride and marketed as Polesaver Rod, was evaluated in laboratory tests against three species of basidiomycete fungi (Coniophora olivacea, Pycnoporus coccineus, Perenniporia tephropora) and two species of subterranean termites (Coptotermes a...

Assessment of wood preservation facilities in Canada
1989 - IRG/WP 3557
This document sets out an assessment procedure for the current status of the wood preservation industry in Canada in relation to the Technical Recommendations (TR) documents for the Design and Operation of Wood Preservation Facilities published by the Government of Canada in April 1988. A questionnaire has been prepared in consultation with industry and the Canadian Institute of Treated Wood. An a...

Literature survey on the permanence and distribution of salt-type wood preservatives
1969 - IRG/WP III 1B
The objective of this survey is generally to review some of the more important published work dealing with the distribution and permanence of salt-type waterborne wood preservatives in treated timber. The survey is limited to the major chrome-containing formulations and the classification system proposed by Becker (1964) has been adopted throughout. CK - chromium, copper (copper, chrome); CKA - c...

Preservatives treatment and field test monitoring of spruce pole stock: CCA and fumigant treatments
1990 - IRG/WP 3619
The fumigants trichloronitromethane (chloropicrin) and sodium N-methyldithiocarbamate (SNMDC) were used to treat red spruce pole stock, either CCA treated or untreated, through holes bored through the pole's center. The poles were analyzed for the presence of microorganisms immediately before ground installation and again after installation at a pole test site. Monitoring of fumigant move...

Screening potential termiticides: Some thoughts and suggestions on methodology
1988 - IRG/WP 1363
While laboratory bioassays on the efficacy of potential termiticides against subterranean termites continues both to dominate and influence research efforts, suggestions are presented for the need to develop laboratory bioassays that more closely simulate "natural conditions". Not only is this considered desirable, but it will offer more confidence in laboratory and field evaluations and their ana...

Biological degradation resistance of pine wood treated with dimethylol compounds
1989 - IRG/WP 3528
The study reports the increase of dimensional stability and biological degradation resistance of pine wood (Pinus sylvestris L) after impregnation with dimethyloldibydroxyethyleneurea. Decay resistance was determined according to BS 838:961. Nearly complete protection against Coniophora puteana, (Schum.ex Fr. Karst) weight loss of 2-3% was shown when modification, expressed as weight gain, exceede...

Methods of treatment of wood preservatives. The selection of appropriate preservation process with particular reference to mixed tropical forest resources. A key address
1982 - IRG/WP 3177
All wood is biodegradable. Many timber species have, however, sufficient natural durability to permit their use, particularly in protected situations, without any special precautions. Many others, of course, are readily attacked by insects and where there is sufficient moisture and air, by wood-decaying fungi. It is these timber species which benefit most from treatment with wood preservatives. Ev...

Report on questionnaire: Facility for accelerated stake tests in unsterile soil
1983 - IRG/WP 2169
In October 1981 a questionnaire (IRG Doc. No. IRG/WP/2166) on the so-called fungus cellar tests in unsterile soil was prepared and despatched to 56 individuals representing various institutes, organisations, or companies. In addition a further 68 letters describing the purpose of the questionnaire were sent to additional IRG members who could request the full questionnaire if appropriate. This rep...

Thermotolerant mould growth in dehumidifier kilns in New Zealand
1996 - IRG/WP 96-10169
Growth of Aspergillus fumigatus and Paecilomyces variottii is common on wood dried in dehumidifier kilns that operate within a temperature range of 35-55°C. Aspergillus fumigatus causes an unacceptable blue / grey discolouration of the woods surface and prolonged exposure to spores during handling of mouldy wood can cause health problems amongst timber workers. A survey of dehumidifier kiln opera...
