Some tests on ES - AS 11, a novel anti-sapstain formulation, and its properties
1987 - IRG/WP 3399
The results of some tests with the formulation ES - AS 11 are given. The formulation is an attempt to improve the performance of an anti-sapstain chemical by: 1) increasing its penetrability 2) uniquely combining its active ingredients. Very short times of treatment (dipping not longer than 5 seconds), low concentrations of active ingredients, and lower toxicological and environmental risks may be...

Termite field test results of preservative treated and modified woods in Kumamoto, Japan
2001 - IRG/WP 01-30275
Various preservative treated or modified wood stakes other than CCA, were buried in the soil, maximum for six years in Kumamoto, south west side of Japan. In this area, two main termite species, Coptotermes formosanus and Reticulitermes speratus, are distributed. After two years in field, untreated sapwood of sugi (Cryptomeria japonica) were observed severe attacks by termites, but the preservativ...

Evaluation by experimentation on site of a new method for termite control
1996 - IRG/WP 96-10173
A new concept of subterranean termite control consists of the installation of toxic baits in or around the infested construction. Dow Elanco has developed a bait system based on Hexaflumuron. This active ingredient is an insect growth regulator with slow acting effect. A lot of trials were conducted in the USA, but none in France until now. We realised on site experiments, in order to estimate the...

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...

The use of chlorothalonil for protection against mold and sapstain fungi. Part 1: Laboratory evaluation
1989 - IRG/WP 3515
Laboratory screening of chlorothalonil alone and in combination with other fungicides was conducted against six mold and sapstain fungi. The most promising treatments appear to be chlorothalonil supplemented with CCA or copper-8-quinolinolate. Field tests have been implemented....

Chemical analysis of TnBTO in lap-joints
1999 - IRG/WP 99-20173
This research was performed as part of the EU project FACT (contract SMT4-CT96-2135) on field tests out of ground contact and ageing methods. The results reported here are part of the work on the experimental lap-joint standard (ENV 12037). TNO investigated the TBTO content of 32 lap-joints by analysing the tin content of 90 samples. The lap-joints were treated with two different TBTO-concentratio...

Preliminary note on the fungal problem of rubber wood
1983 - IRG/WP 3246
Susceptibility of rubber wood to fungal attack limits its wider utilisation. Fungal problems encountered in treating rubber wood with boron compounds by diffusion process have been discussed. Sodium pentachlorophenoxide and 2-thiocyanomethylthio benzothioazole (TCMTB) were investigated for possible control of fungal growth during diffusion storage and their performance has been reported....

The preliminary evaluation of selected sulfonium salts for use in wood preservation
1984 - IRG/WP 3278
Five sulfonium compounds, including two sulfonium methosulfates, one sulfonium bromide and two amphoteric sulfonium propanesulfonates, were prepared in crude form and subjected to various biocidal screening tests. A rapid screening test in which treated Pinus radiata pulp pellets were exposed to one of three wood-decaying fungi growing on malt agar revealed that dodecyl dimethyl sulfonium methosul...

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 ...

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...

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...

Evaluation of an alkyl ammonium compound as a fungicide to control sapstain and mould during diffusion storage
1984 - IRG/WP 3282
An alkyl ammonium compound ('Akzo' ES 255) was evaluated for its effectiveness against mould and sapstain during diffusion storage of boron-treated rubber wood. Though ES 255 at 1.0% concentration was effective against mould (71%) and sapstain (89%) it is less satisfactory compared to 0.5% sodium pentachlorophenoxide against mould (92%) and sapstain (98%)....

Tolylfluanid - fungicide against blue stain in service
1992 - IRG/WP 92-3736
Physical and chemical properties and efficacy of Tolylfluanid are compared with the properties of Dichlofluanid. Whereas the difference in the molecular structure influences the physical properties significantly, the efficacy of both fungicides is comparable. The toxicological and ecotoxicological profile of Tolylfluanid is summarised....

Tunneling ability of subterranean termites through termiticide-treated soil
1988 - IRG/WP 1375
A test apparatus was designed to facilitate accurate measurement of termite penetration into termiticide-treated soil; three termiticides at 500 ppm were evaluated. Coptotermes formosanus Shiraki workers tunneled significantly farther into chlordane-treated soil than did Reticulitermes flavipes (Kollar). Both species only slightly penetrated chlorpyrifos-treated soil. Neither species penetrated so...

Laboratory and field evaluation of Plasmite Reticulation System using bifenthrin as a chemical barrier within wall cavities against subterranean termites.
2005 - IRG/WP 05-20307
Laboratory and field bioassays undertaken to demonstrate Plasmite Reticulation system effectively delivers the termiticide (bifenthrin) within a simulated wall cavity at the required concentration. The chemical assay indicated that the amount of bifenthrin sampled at 5, 10, 15, 20, and 25m along the simulated reticulation system tested (30m) exceeded the manufacturer’s minimum recommendation of ...

Effect of borate on uptake and efficacy of an anti-sapstain treatment
2005 - IRG/WP 05-30380
The potential for using borates to enhance uptake and efficacy of propiconazole-based anti-sapstain chemicals was assessed on ponderosa pine sapwood wafers. Borates had no consistent effect on either net solution absorption or propiconazole distribution in the wood. Even small amounts of borate, however, markedly improved the performance of propiconazole against fungal discoloration. These resul...
