Some experiments with hexabutylditin against fungi
1977 - IRG/WP 388
The investigation was carried out in 1972 and 1973 to collect experimental data about the poisonousness of hexabutylditin (HBDT) against the woodrotting fungi Coniophora puteana (Coniophora cerebella), strain 15, and Chaetomium globosum, strain hexabutylditin was being manufactured by the Organisch Chemisch Instituut (O.C.I.) TNO, at Utrecht....

Experimental test site to prevent maritime pine logs from bluestaining: water-spraying and water-immersion methods
2003 - IRG/WP 03-10497
Following a storm which led to windfall wood, a research project was launched to develop preservation methods with a low environmental impact for maritime pine logs. These preservation methods are intended to be suitable for large-scale storage areas of maritime pine. In addition the aim was to maintain wood quality during long term storage. An experimental field test with 1 900 m3 of maritime pin...

Effect of methylene bisthiocyanate on morphology and ultra-structure of a sapstain fungus, Ophiostoma floccosum
2003 - IRG/WP 03-10471
In vitro effects of methylene bisthiocyanate (MBT) on hyphal morphology and ultrastructure of Ophiostoma floccosum were examined using differential interference contrast, epifluorescence and transmission electron microscopy (TEM).
Differential interference contrast microscopy suggested that MBT caused rapid changes to the morphology of O. floccosum resulting in excessive formation of vacuoles and...

Framework document for an international code of good practices for wood preservation and wood protection (anti-sapstain) facilities
1992 - IRG/WP 92-3683
At the Kyoto meeting, the Health & Safety committee agreed to form a task force to prepare a global plan for writing a code of good practices (Code) for wood protection and preservation facilities (Doc. No. IRG/WP/3681). The Canadian document had been presented to the IRG group earlier (Doc. No. IRG/WP/3447) and similar documents were solicited from other countries for preparing a framework do...

An evaluation of anti-apstain chemicals in Queensland, Australia
1986 - IRG/WP 3374
Five formulations were evaluated for potential use as antisapstain chemicals. Tolcide FSM (0.01, 0.02, 0.04%), Koppers N.P.-1 (0.70, 0.35, 0.25%), Kathon WT (0.10, 0.25, 0.40%) and Sinesto B (2.5, 5.0 and 7.5%) offer potential as antisapstain treatments. An incorrect stock of Busan 1009 was used resulting in unacceptable results....

Characterization of glycopeptide from white-, brown- and soft rot fungi
2002 - IRG/WP 02-10424
Extracellular low-molecular-weight substances that catalyze a redox reaction between O2 and electron donors to produce hydroxyl radicals have been isolated from wood degrading cultures of white-rot, brown-rot, and soft-rot fungi. They contained protein, neutral carbohydrate, and Fe(II). These substances were glycosylated (glycated) peptides and suggested to form Amadori product (ketoamine). The...

Detection of semi-quantitative and qualitative enzymatic activities of blue-stain fungi
2000 - IRG/WP 00-10347
Blue-stain, produced in forests, continues to be a problem in countries of moderate climate. In forestry, in certain geographical areas of Spain, it has been observed that anti-sapstain products have not always been efficient, as their fungicidal effectiveness varies on occasion, depending on the species of wood and microbiota that exist in the region. It is not always easy to identify the species...

Wood decay in Danish buildings
1985 - IRG/WP 1261
At Technological Institute identification of fungi and advisory activity concerning repair of damages has taken place since 1935. Statistical analyses based on material from 1982 and 1983 are compared to earlier investigations worked out by L. Harmsen. The material shows that building traditions influence the diversity and frequency of fungal species. Many fungal damages in the last decade have sh...

Examination of timbers from the Mary Rose in storage
1988 - IRG/WP 4149
Timbers from the Tudor ship, Mary Rose, have been examined for the presence of fungal fruiting structures. Wood specimens were also examined for the presence of microbial decay patterns using light and scanning electron microscopy. Structural timbers were surveyed using the Pilodyn for an overall picture of the extent of decay. Mary Rose timbers were predominantly inhabited by marine fungi. Fourte...

Influence of abiotic factors on the production of Basidiocarps by lignocellulolitic Hymenomycetes from native forest and plantations of Pinus elliottii Engelm in the Fontes do Ipiranga State Park, São Paulo, Brazil
1991 - IRG/WP 1469
A report on the influence of abiotic factors on the production of basidiocarps by lignocellulotic Hymenomycetes of native forest and Pinus elliottii. It was concluded that the climatic conditions (temperature, humidity, microhabitat) and the decay stage of the logs affected the production of basidiocarps by Hymenomycetes....

Proposed degradation pathway for quaternary ammonium compounds by mould fungi
1996 - IRG/WP 96-10166
One group of chemicals that has attracted considerable attention as potential wood preservatives are the quaternary ammonium compounds (QACs). Based upon results of previous research this study confirmed the degradation pathway employed in QAC-tolerant fungi. For this experiment the two dialkylammonium compounds didecyldimethylammonnium chloride and dioctyldimethylammonium chloride were used. QAC-...

Effects of some essential oils on wood destroying organisms
1993 - IRG/WP 93-10047
Three wood destroying fungi: Botryodiplodia theobromae Pat. (stain), Gloeophyllum sepiarium (brown rot), and Pycnoporus sanguineus (white rot) were exposed to six plant essential oils: the peppermint, kaffir lime or leech lime, lavender, tarragon, holy basil, and the eucalyptus. The peppermint oil showed most effective to inhibit fungal growth, while eucalypus oil was the least effective. The othe...

Effect of asphyxiation on wood decay fungi treated
with argon and nitrogen gas
2002 - IRG/WP 02-10452
The effects of low-oxygen conditions, achieved with either argon or nitrogen gas, on the viability of wood decay fungi Coniophora puteana, Antrodia vaillantii and Trametes versicolor, cultivated on PDA medium and infected wood samples, were examined. The fungal cultures were exposed to low oxygen concentration (below 10 ppm) for one to five weeks in hermetically sealed vessels. Anoxic treatment di...

Use of fluorescent-coupled lectins as probes for studying fungal degradation of wood
1986 - IRG/WP 1288
The ability of the fluorescent-coupled lectins wheat germ agglutin (WGA) and Concanavalin A (Con A) to react with selected Basidiomycetes, Ascomycetes, and Fungi Imperfecti was evaluated using pure cultures of 35 fungi grown on malt extract agar. WGA, which binds specifically to the n-acetylglucosamine residues found in fungal chitin, reacted with nearly all hyaline fungal structures but did not r...

A field test with anti-sapstain chemicals on sawn pine timber in Finland
1986 - IRG/WP 3368
Fourteen formulations, each in two concentrations, were tested for effectiveness against sapstain, mould and decay on Scots pine (Pinus sylvestris L.) in a field test in South-Finland. The trial was commenced in June 1985 and finished in October 1985. During the test the boards were infected mainly by mould fungi. In kiln dried boards the protective effects of nine and in green boards of four trea...

Biological effectiveness of ground-contact wood preservatives as determined by field exposure stake tests
1984 - IRG/WP 3297
Field exposure tests conducted on stakes treated with different creosotes, mixtures of creosote and waxy oil as well as different CCA wood preservatives over a period of 25 years, gave the following results: The CCA preservatives provided excellent biological protection to treated stakes, especially against fungal attack. The CCA Type I, currently approved for use under South African conditions is...
