Evaluación de oxinato cúprico como alternativa al tribromofenato de sodio, para uso como funguicida antimancha. Ensayo final y conclusiones
2008 - IRG/WP 08-30481
This study evaluated the efficacy of oxine-copper (Cas Nº 10380-28-6. Synonyms: copper oxyquinolate, cupric-8-hydroxyquinolate, copper-8-quinolinolate) for the control of stain fungi in lumber. Three field tests were established and sodium tribromophenate was used as a reference preservative. Boards of Pinus elliotis and P. taeda were treated by dipping for 15, 30 or 60 seconds in two different f...

Evaluation of a new anti-sapstain formulation
1994 - IRG/WP 94-30035
A new anti-sapstain mixture, which consists of 2% IPBC (3-iodo-2-propynylbutyl carbamate) and 1.5% DCOI (4,5-dichloro-2-n-octylisothiazolin-3-one), was evaluated by three methods in the laboratory. A standardized test (JWPA standard 2) demonstrated that the new anti-sapstain formulation was highly effective in controlling growth of monocultures of five test fungi on wood substrate. When exposed to...

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...

Thermotolerant moulds on timber during kiln drying
1980 - IRG/WP 1109
In recent years a special disease named the wood trimmer&apos;s disease has been observed with increasing frequency among saw mill workers. Particularly workers in the trimming department have been affected. The medical symptoms are usually high fever, ague headache, pain in muscles and joints. It was shown that the disease was of immunologic nature and caused by over-exposure to spores from m...

Laboratory evaluation of anti-sapstain formulations
1989 - IRG/WP 3510
Four formulations were tested for their efficacy in controlling molds and sapstaining fungi on wood according to the Standard-II of Japan Wood Preserving Association (JWPA). Relative efficacy was compared on the basis of visual rating of the fungal growth on the treated and untreated wood surfaces when the wood specimens were exposed to each monoculture of 5 test fungi at 26±2°C and 70-80% for 4...
