Preliminary study of the fungicidal and structural variability in copper naphthenates and naphthenic acids
1996 - IRG/WP 96-30114
Copper naphthenates, an oil-borne wood preservative listed by the American Wood-Preservers' Association (AWPA), is manufactured by complexing copper(II) with naphthenic acids. Prior to AWPA listing as a wood preservative, field experiments showed that copper naphthenates generally had good stability and were active against wood-destroying organisms. Recently, however, there have been reports ...

Fungicidal activity of some organic solvents, copper carboxylates and their complexes with 2-aminoethanol
1997 - IRG/WP 97-30136
We evaluated the activity of eight organic solvents against wood - rotting fungus Trametes versicolor in order to choose the most appropriate one for rapid screening tests of some copper(II) carboxylates and their adducts with 2-aminoethanol. Their activity against the selected fungus was classified in the following order: chloroform > N,N-dimethylformamide > acetonitrile > methanol > ...

The evaluation of synergistic effects of chemicals on fungicidal efficacy in crossed-paper tests
1991 - IRG/WP 2383
The mixing effects of wood preservatives were evaluated using the crossed-paper technique. Two filter paper strips (0.7 x 8 cm²) were treated by soaking with different chemicals [fungicides, a termiticide (chlorpyrifos or phoxim), a surface-active agent, a synergistic agent, and a stabilizer], and placed at right angles to each other on a fully grown mycelial mat of a test fungus in a Petri dish....

Fungicidal combination products
1987 - IRG/WP 3426
Due to the increased pressure on some of the established fungicides used in wood preservation, possible alternative products become more interesting. The requirements for new chemicals are mainly lower toxicity and greater environmental acceptability. However the efficacy to target organisms should be as good as that of the currently used ones, preferably better. A possibility for progress in this...

Boron treatments for the preservation of wood - A review of efficacy data for fungi and termites
1994 - IRG/WP 94-30037
Boron treatments have been used for many decades for protection of timber from biological attack and also as a fire retardant treatment. In recent years there has been an increased interest in boron treatments as an option for protection of structural timbers' e.g. timber framing used in termite risk areas. This paper reviews efficacy data for both fungi and termites relevant to this end-...

Long-term protection of stored lumber against mould, stain, and specifically decay: A comparative field test of fungicidal formulations
1984 - IRG/WP 3281
The problem of decay in packaged, unseasoned lumber stored for many months has become of major importance in recent years. Large financial claims have resulted from decay in Canadian lumber stored at length in seaports and storage yards of distributors. For decades acceptable protection from moulds and sapstain was readily achieved with chlorinated phenols applied at appropriate treating levels. H...

New boron-based biocides for the protection of wood
2002 - IRG/WP 02-30283
Boric acid and other simple inorganic oxides of boron are amongst the oldest wood preservatives currently in use. Their relatively low toxicity and broad-spectrum activity are just some of their desirable characteristics. The primary disadvantage associated with conventional boron-based preservatives is their lack of permanence in exposed applications. A collaborative project between CSIRO and the...

Evaluation of the insecticidal efficacy of deltamethrin and the fungicidal efficacy of its association with TCMTB + MBT in the field of wood preservation
1986 - IRG/WP 1289 E
Deltamethrin possesses many advantages for the insecticidal protection of wood: relatively low toxicity, very reduced evaporation, very prolonged retention in the wood, very slight leaching after having penetrated the wood, and absence of odour. Its association with other active agents or solvents is being studied with regard to chemical compatibility. Compatibility studies have proved positive fo...

Fungicidal properties of wood tar being a side product of pyrolysis of previously treated wood with preservatives
2004 - IRG/WP 04-30340
The objective of the paper was to estimate the limit of the fungicidal value of wood tar being a product of pyrolysis of wood previously treated with creosote oil or salt preservative of the CCB type. The effectiveness of wood tar in wood protection against fungi causing brown rot and soft rot was compared to the effectiveness of creosote oil (type WEI-B). Wood was impregnated with alcohol solutio...

Fungicidal effectiveness of amended alkylammonium compound
1987 - IRG/WP 3421
Amendment of didecyldimethylammonium chloride was attempted to improve its fungicidal effectiveness and properties of treating solutions. Addition of copper definitely increased effectiveness in controlling wood decay fungi, although metal corrosiveness and stability of treating solutions was unsatisfactory. Further amendment with stabilizer(s), anticorrosive agent(s) and sequestering agent(s) res...

Gaseous treatment of timber with allyl isothiocyanate. Fungicidal and insecticidal effects
1996 - IRG/WP 96-30108
Gaseous treatment with allyl isothiocyanate (AIT) was tested for its effects on the growth of microorganisms on the wood substrate and the mortality of subterranean termites and powder-post beetles. Toxic limits of AIT were determined as concentrations in the air when an AIT-treated filter paper was placed in a sealed container with fungus-inoculated wood specimens. Those were <3.8 ppm for Aure...

Reappraisal of some fungicides by the amended JWPA method
1992 - IRG/WP 92-3689
Organoiodine compounds which have been commercialized these years in Japan poorly performed as fungicides in the amended JWPA decay test (Standard 1, 1989) when applied to superficial treatment of timber. Because some parts of active ingredients seemed to disappear from the treated timber surface mainly due to the severe leaching cycles. This was prominently true for beech (Fagus crenata Blume) sa...

Growth inhibitory effects on blue-stain fungi of applied electricity fields
1996 - IRG/WP 96-10167
Exploratory laboratory experiments on the effects of electricity on two blue stain fungi Aureobasidium pullulans and Ceratocystis piceae on wood revealed that a potential gradient of 1 V/cm corresponding to a current of 15 mA (DC), applied without interruption during a 2 week experimental period, leads to an inhibition of the growth of these fungi. Germination is somewhat more sensitive than mycel...
