An alternative method for the determination of lignocellulolytic enzymatic activities of white rot fungi
1998 - IRG/WP 98-10261
Some lignocellulolytic activities of wood decay fungi can be evaluated in an indirect way through the study of the decolorization that white rot fungi produces in culture media in the presence of dyes.
In this assay, ten dyes were selected, which were added i…

The effect of alternative pre-conditioning procedures on the durability of wood based board materials to decay fungi
1997 - IRG/WP 97-20105
…method is used to remove this effect. A variety of alternative ageing procedures have been studied, including natural weathering, leaching and evaporative procedures, to determine the most appropriate pre-conditioning protocol for the decay test. Our results show that there are procedures which are more…

Alternatives to preliminary oven-drying prior to spot-testing treated timber for borate or TBTN preservative penetration
1995 - IRG/WP 95-20067
…Modifications to the spot-testing procedures, involving alternative solvents and acidification conditions, have allowed the preliminary oven-drying step to be replaced by a very short heating period after application of the reagents, reducing the total testing time to a few minutes. Reliability of the modified…

LCA examination of preservative treated timber products and alternatives; initial results
1995 - IRG/WP 95-50040-04
…suitable for application to preservative treated products has been carried out, based on scoping assessments of two products, CCA treated fenceposts and creosote treated distribution poles. The general results of these scoping exercices are described, based on the CCA case study. These include the…

Safer alternative reagents for colour differentiation of heartwood and sapwood
1994 - IRG/WP 94-20028
…but also out in the timber processing chain. Safer alternative reagents have been proposed over the past twenty years, but some of these have since been linked with health problems, and most of the rest lack the specificity and general usefulness of those traditionally used. Recent research has investigated…

Elimination of alternative explanations for the effect of iron on treated wood
1993 - IRG/WP 93-30006
Amounts of iron which had previously been found in stakes removed from ground contact reduced decay of untreated wood by four brown-rot fungi. This suggested that the effect of iron may be on the preservative. Analysis of the leachates from CCA- and ACA-treate…

Shorter-term biological control of wood decay in pre-seasoning pine roundwood as an alternative to chemical methods
1992 - IRG/WP 92-1555
Previous studies on the long-term control of decay in creosoted transmission poles, using Trichoderma and other antagonistic moulds, have met with limited success. However, it is possible biological control is more suited to control of decay on shorter time sc…
