Utilization of plasma treatments in the field of wood protection
2021 - IRG/WP 21-40912
Plasma treatments have been used for modification of surfaces of wood and wood-based materials for some decades and solutions were developed to apply it for wood protection. This contribution aims to present the background, introduce the available plasma technology, and to give an overview on the typical applications and benefits....

Protection of rubberwood with modified creosote
1998 - IRG/WP 98-30165
Creosote is a renowned wood preservative but has certain disadvantages like obnoxius odour and colour, with its unpaintability and bleeding from wood surface may create environmental hazards. An effort has been made to isolate chemical fractions from creosote to obtain clean odourless preservative formulations by subjecting to steam distillation (SVC). Rubberwood treated with SVC and tested for it...

Sentry®, a new antisapstain formulation for protecting logs and lumber. - Part 2: protection of lumber
1999 - IRG/WP 99-30189
Recent research conducted by Forest Research, Chemcolour Industries (NZ) Ltd. and Fletcher Challenge Forest Ltd. has resulted in the development of antisapstain formulations that meet the efficacy requirements of the New Zealand Forest industry for export logs. One treatment, called Sentry®, is now poised for commercial use in New Zealand for treating export logs, having undergone an extensive su...

An appraisal of methods for environmental testing of leachates from salt-treated wood; part 1
1998 - IRG/WP 98-50115
The magnitude and diversity of leaching tests with salt-treated wood, performed by institutes as well as industry, strongly appeal for harmonisation towards one single method. That procedure should be well-defined, cost- and time-effective and moreover be extended with a clear detection and interpretation scheme.
The paper(s) presented here tend to evaluate 2 existing leaching methods, the ENV 12...

Unsuitability of the limiting dose as a criterion for assessing the toxicity of preservatives to wood-destroying fungi
1974 - IRG/WP 243
In the majority of methods for investigating preservatives for wood-destroying fungi their toxicity is assessed by determining what is called the "limiting dose". This normally denotes a range of preservative solution concentrations or retentions of dry preservative in the timber, the lower value serving to indicate the amount of preservative at which is observed the expected effect, e.g. the grow...

Protection of wood blocks treated with Trichoderma isolates selected on the basis of preliminary agar screening studies
1996 - IRG/WP 96-10154
Previously reported results of agar interaction screening studies for biocontrol agents of wood decay basidiomycetes showed two Trichoderma viride isolates, killed 16 of 19 target fungi (Tucker and Bruce, 1995). Testing of these isolates in wood was required to assess their performance at preventing decay of wood blocks. Standard testing of chemical wood preservatives is used to determine the toxi...

Alternatives to CCA for ground contact protection of timber: a perspective from UK on performance and service life expectations
2002 - IRG/WP 02-30289
The proposed amendment to the European Union's Marketing and Use Directive (1976/769/EEC) in respect of arsenic in CCA wood preservatives seeks to restrict the use of CCA across the European Union. CCA is an extremely important wood preservative in the UK from the manufacturing of the product to the extent of use of CCA-treated timber. Based on our experience and judgement on the use of ...

FIPRONIL - une nouvelle molécule insecticide Rhône Poulenc pou le PCO et la protection du bois [FIPRONIL - A new insecticide from Rhône Poulenc for PCO and wood preservation]
1995 - IRG/WP 95-50040-16
We will explain here after the advantages and key points of the new insecticide "FIPRONIL" from Rhône Poulenc Agrochemicals. We will have a look from the physical and chemical properties to the possible uses in PCO and wood preservation, including toxicology, efficacy and the main beneficial impacts on the environment. FIPRONIL, a new solution against undesirable and damageable insects, from cock...

Composting of waste building up in sawmill dipping basins
1990 - IRG/WP 3570
We have studied composting of waste building up in dipping basins at sawmills although this waste can also be disposed of by incineration. Controlled composting within the sawmill area seems to be a feasible method. Another possibility is to accomplish composting directly at the local dumping site. Waste containing antistain chemicals is generally classed as hazardous. It cannot therefore be place...

Protection of southern pine using N,N-Napthaloylhydroxylamine: Field tests, soft-rot cellars and aquatic bioassay leach testing
1999 - IRG/WP 99-30204
Recent environmental restrictions are limiting the use of broad-spectrum biocides for wood preservation. There is an urgent need for new, sharply targeted, environmentally benign wood preservatives. N'N-Napthaloylhydroxylamine (NHA), a water-soluble calcium-precipitating agent, has been shown to inhibit decay by brown-rot and white-rot fungi in soil-block tests and prevent damage by Easte...

Suitability of cyfluthrin in wood protection
1992 - IRG/WP 92-3735
Cyfluthrin, a well-known and in agriculture and household widely used insecticide based on synthetic pyrethroides, is evaluated now concerning its suitability as insecticide in wood protection. An overview about the physical and chemical properties is given. Test results in accordance with European standards show the high efficacy and broad-spectrum activity of Cyfluthrin against wood rotting inse...

Qualifying ecotoxicity research on tropical hardwood leachates
1997 - IRG/WP 97-50096
Almost as a rule, quantification and identification of various types of environmental contamination is grounded on chemical evaluation principles. Yet for monitoring surface water pollution, aquatic bio-assays may provide a more direct way to assess the potential hazard of environmental samples. A battery of such tests is experienced onto leachates of tropical hardwoods used in ground and water co...

Efficacy of anhydrides as wood protection chemicals
1997 - IRG/WP 97-30162
Wood samples treated with anhydrides of various compositions have been examined for their decay resistance and moisture behaviour. For this purpose two brown rot fungi (Coniophora puteana and Gloeophyllum trabeum) and two white rot fungi (Trametes versicolor and Pycnoporus sanguineus) were used in conventional and modified soil block tests. The modified soil block tests conformed to the method as ...

New approaches to practical evaluation method of bio-degradation of wooden construction - Non-destructive detection of defects using radar technique
2000 - IRG/WP 00-20214
There have been a number of researches and developments on the techniques and apparatus for the nondestructive evaluation of the biological deterioration in wood and wooden constructions, such as decay or insect attack in house, public buildings or in historically important architectures. As for the detection of the decay in wood, techniques using sound in audible or in ultrasonic frequency ranges...

Fumigation of New Zealand grown western red cedar for export markets
2001 - IRG/WP 01-30262
The objective of this study was to demonstrate that methyl bromide fumigant penetrates into the centre of western red cedar (Thuja plicata L.) timber to meet the standard for export markets. Kiln dried western red cedar was used and a cavity (50x 30 x 13mm3) was prepared into the centre of each sample board (500 x 200 x 26 mm3 thick). An absorbent sachet used in industry for cross checking that th...
