Investigation of the fixation in wood of chromated zinc chloride and copperised chromated zinc chloride preservatives
1976 - IRG/WP 372
A biological method of evaluating the extent to which CZC and CCZC preparations are retained in wood in terms of the potential protection which they afford against destruction by Merulius lacrymans (dry rot) is given. CCZC is recommended for protection of wood under moderate leaching conditions, while the use of CZC under such conditions is not recommended....

Development of a method for testing wood preservatives with soft rot fungi
1975 - IRG/WP 250
Although the first publications on experimental soft rot attack date back 20 years ago, so far no test method for evaluating the efficacy of wood preservatives against soft rot attack (Ascomycetes and Fungi Imperfecti) has been generally accepted. The reasons are diverse and the shortcomings and the disadvantages of the methods described are well known and have repeatedly been discussed. The soil ...

Involvement of hydrogen peroxide in wood decay by brown-rot and white-rot fungi
1985 - IRG/WP 1256
To gain further understanding of the role of H2O2 in wood degradation by brown- and white-rot fungi, we studied the following: (a) extracellular H2O2 production, (b) effect of various hydroxyl radical (·OH) and singlet O2 (1O2) quenching agents on wood and cellulose degradation, (c) intracellular H2O2 production and catalase activity, and (d) cytochemical localization of H2O2 with diaminobenzidin...

Fungicidal properties of boron containing preservative Borosol 9
2004 - IRG/WP 04-30348
The fungicidal properties of new boron containing wood preservative Borosol 9 is described in this paper. These properties were of particular interest as this new boron containing preservative, exhibit very good performance against wood damaging insects. But because the tested boron formulation contain also nitrogen compounds, we wanted to verify if nitrogen as a nutrient could promote...

Damage by wood-attacking insects in buildings in Sao Paulo State - Brazil. (including errata slip)
1978 - IRG/WP 175
From 1974 to 1978 up to 602 buildings attacked by wood-boring insects were inspected by Instituto de Pesquisas Tecnologicas in Sao Paulo State - Brazil. Damage was caused mainly by subterranean termites, dry-wood termites and wood-attacking beetles. Up to US $ 1000,000 is the amount needed to control such insects in the buildings inspected...

Investigations on the life cycle and nutrition of Criocephalus rusticus L
1974 - IRG/WP 127
The longhorn beetle Criocephalus rusticus L or Arhopalus rusticus (L) is widely distributed in Europe and Asia. It attacks softwoods. The primary host trees are pines, ie freshly felled, unbarked logs, dying standing trees and stumps. After feeding under the bark the larvae enter the sapwood and also the heartwood. Timber to be used for building purposes may be rendered useless by their tunnelling...

The leachability and specificity of the biological protection of timber using Scytalidium sp. and Trichoderma spp
1986 - IRG/WP 1302
The results of field experiments, using biological control against internal decay of creosoted poles, are briefly reviewed and the evidence concerning the leachability of the antibiotics produced by these species is presented. A pure culture miniblock decay test on biological control treated pine sapwood is described and the results compared to previously published data. The protection against Len...

Copper based water-borne preservatives: The use of a thin section technique to compare the protection of wood by copper based preservatives against soft-rot and bacterial decay
1987 - IRG/WP 2286
This paper describes the techniques developed and gives examples of results obtained for the performance of copper based wood preservatives against both the bacterial and fungal hazards....

Ibuprofen inhibits in vitro growth of brown-rot fungi
1996 - IRG/WP 96-10160
Ibuprofen, a phenyl propionic acid derivative (2-(4-isobutylphenyl)propionic acid) inhibited growth in vitro of 17 brown-rot fungi at a concentration of 100 µg/mL, while exhibiting no growth inhibition for 8 white-rot fungi at the same concentration. Propionic acid did not inhibit fungal growth in vitro. Morphological changes were noted in fungi that were able to grow in the presence of ibuprofen...

Fungi associated with groundline soft rot decay in copper/chrome/arsenic treated heartwood utility poles of Malaysian hardwoods
1992 - IRG/WP 92-1567
Copper-chrome-arsenic treated heartwood from Malaysian hardwood utility poles in service for 8-23 y at two localities in the wet tropical Peninsula Malaysia were surveyed for soft rot in the ground-contact region. Soft rot decay was detected in all the poles. Isolation studies indicated the ability of a variety of microfungi and basidiomycetes to colonize treated heartwood. Most isolates exhibited...

Antifungal properties of new quaternary ammonium and imidazolium salts against wood decay, staining and mould fungi
2004 - IRG/WP 04-30347
The biological activity of twenty-four potential wood preservatives – imidazolium and quaternary ammonium salts with a modified anion structure was determined employing screening agar-plate and agar-block methods. Experiments were carried out on Scots pine (Pinus sylvestris L.) wood. The aim of the performed studies was to investigate the effect of structure modification of IC and QAC with organ...

An experimental method to simulate incipient decay of wood by basidiomycete fungi
2000 - IRG/WP 00-20200
At very early stages of decay of wood by basidiomycete fungi, strength loss can be measured from wood before any measurable weight loss. Therefore, strength loss is a more efficient measure of incipient decay than weight loss. However, common standard decay tests (e.g. EN 113 or ASTM D2017) use weight loss as the measure of decay. A method was developed that allowed progressive removal of samples ...

Correlation between a laboratory bioassay and field trial conducted to determine the termiticidal effectiveness of bifenthrin
2002 - IRG/WP 02-20248
Details are given of a laboratory bioassay and field trial undertaken to determine the termiticidal effectiveness of the synthetic pyrethroid bifenthrin, when impregnated into Pinus radiata D. Don sapwood specimens. Results show a strong correlation between the laboratory and field methods of evaluation. Protection threshold limits obtained were the same for the two test species of termite employe...
