Anti-stain field trials in British Columbia
1981 - IRG/WP 3174
Four alternative anti-sap stain chemicals were subjected to a four month field evaluation during the summer of 1980. The test, established at a Vancouver Island sawmill, was designed to evaluate the potential long-term effectiveness of sodium tribromophenate (Velsicol Ltd.), Biocom XX (Bramco Industries) containing methylene bis-thiocyanate, Woodbrite NTX (Van Waters & Rogers Ltd.) containing ...

A comparative field test of the effectiveness of anti-sapstain treatments on radiata pine roundwood
1986 - IRG/WP 3376
Peeled radiata pine posts were sprayed with one of six antisapstain formulations, with and without a wax water-repellent additive, to evaluate the protection given by each treatment. After 3 months' outside storage the best treatments tested were 4% product Busan 30, 2% product Busan 1009, and 2% active sodium pentachlorophenoxide (NaPCP) with 1.5% borax. After 6 months' storage ...

Termiticidal chemicals derived from tropical tree resins
1991 - IRG/WP 1477
To test the hypothesis that defensive chemicals protect tropical primary forest trees against biological attack, a bioassay and fractionation program was conducted in Indonesia. Fresh dipterocarp resins were fed in no-choice tests to Neotermes dalbergiae termites on 4.5 cm filter papers, or tested for inhibition of fungal growth. Fractionation of biologically active resins via flash column chromat...

Observations on the penetration of preservatives into green timber
1985 - IRG/WP 3335
Differences in the rate and extent of diffusion of MBT and NaPCP-based preservatives following a short dip treatment were observed. The importance of preservative distribution as well as toxicity to the target organisms in governing the ultimate performance of any anti-sapstain compound is discussed....

The use of bifluorides-diffusion in remedial treatments
1983 - IRG/WP 3256
A description is given about the experience to date of a 14 years' development to bring bifluorides-diffusion from laboratory evaluation to commercial service application. The described treatment is an adjunct to good design and not a replacement for it. The process is also used with an injection method for the remedial treatment of premature decayed external joinery....

Seasonal effects of the field evaluation on wood preservatives against mold fungi
1996 - IRG/WP 96-20087
For the purpose of the amelioration of field test methods, commercial preservatives against mold fungi were tested under two different seasons, in winter and in summer. The specimens were bundled and set over the water bath and all these systems were covered with plastic film. At top of the system under film, black films for regeneration of sunlight were put in, and windows for changing air were 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...

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....

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...

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...

Field and laboratory studies on anti-sapstain preservatives
1982 - IRG/WP 3205
The field tests included 11 different anti-sapstain preservatives and were carried out at different sawmills in southern Sweden. Drying conditions, climate and the local fungus flora were not identical for the different preservatives and comparisons between the preservatives should therefore be made with caution. Results obtained in the field tests are, however, in relatively good agreement with t...

Wood preservation in Kenya
2000 - IRG/WP 00-40191
Current research on wood preservation in Kenya is mainly on the development of biological control of wood-destroying termite species, using mycoinsecticides. The major research institutions include the Kenya Agricultural Research Institute (KARI), Kenya Forestry Research Institute (KEFRI), Moi University and the International Centre for Insect Physiology (ICIPE). Training institutions include Fore...

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....

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...

Protection of beech veneer for fruit and vegetable boxes
1981 - IRG/WP 3176
In Yugoslavia about 50,000 m³ of low quality beech logs annually are rotary cut into veneer from which boxes are made for transporting fruit and vegetables. Because of steaming before rotary cutting, beech veneer becomes extremely sensitive to mould attack which decreases the quality and commercial value of the final product. To avoid mould attack, veneer sheets are dried to 16% moisture content ...
