Prevention of fungal damage of oil and date palm wood by organic acids
2017 - IRG/WP 17-10877
Felled palm trunks are susceptible to fungi as long as their moisture content is above fibre saturation. During this period, palm wood has to be protected against mould and rot fungi. Environmental-friendly organic acids are suitable. Small samples of oil palm (Elaeis guineensis) and date palm (Phoenix dactylifera) wood were treated with 1 to 10% solutions of acetic acid and propionic acid, respec...

Activity of Two Strobilurin Fungicides Against Three Species of Decay Fungi in Agar Plate Tests
2017 - IRG/WP 17-30704
The objective of this study was to examine the toxicity of strobilurin fungicides against wood decay fungi in order to assess their potential to act as a co-biocide for copper-based wood protection. Two strobilurin fungicides, Heritage (50% azoxystrobin active ingredient) and Insignia (20% pyraclostrobin active ingredients), and copper sulfate pentahydrate were tested against one white rot fungus...

Glueline fungicides in veneer based engineered wood products – updated results from laboratory work for the H1.2 hazard class in New Zealand
2018 - IRG/WP 18-30726
Results from New Zealand H1.2 ‘bin’ trials containing plywood glueline treated with triadimefon and cyproconazole were reported in 2012 (IRG/WP 12-30593). One of these trials has continued to the present day (2108) and updated results of this trial are reported. The triadimefon and cyproconazole glueline treatment continues to compare with, or outperform, the reference preservative used, bei...

Monitoring of wood preservatives exposed to weathering: Extraction and analysis methods of organic biocides from treated wood and collected rain runoff
2020 - IRG/WP 20-30753
Weathering is the cause of numerous damages for outdoor joineries. Protection of wood using a preservative treatment covered with a coating is a process widely used to limit these damages. However, biocides from preservative treated wood are prone to degradation and leaching, having a direct influence on the joinery service life. This document deals with extraction and analytical methods for bioci...

Effect of MVOC exposure on mycelial growth of wood rotting fungi
2021 - IRG/WP 21-10977
It is well known that wood rotting fungi produce microbial volatile organic compounds (MVOCs) as metabolites. In our previous studies, we have found that some MVOCs produced by wood rotting fungi are common to fungal species tested in the studies, while others are specific to each species. Furthermore, it has been also shown that each wood rotting fungi do not always produce the same type of MVOCs...

Effect of volatile organic compounds produced by wood rotting fungi on mycelial growth
2023 - IRG/WP 23-11023
Microorganisms such as fungi or bacteria produce volatile organic compounds (so-called MVOCs: Microbial Volatile Organic Compounds) as metabolites. Some MVOCs have been found to be biologically active, for example inhibition of spore germination, and when fungi of different species encounter each other, the MVOCs pattern change, suggesting that MVOCs play a role as a mediator for biological intera...

Developing thermal-energy storage systems based on Kraft lignin-glyoxal and organic phase-change material modified wood
2024 - IRG/WP 24-30810
This study investigated the use of modified wood as a thermal-energy storage material through the integration of paraffin-based phase-change materials (PCMs). The objective was to evaluate the influence of Kraft lignin-glyoxal prepolymer on the properties of wood modified with PCMs. The implementation of the modified wood involved preparing PCM emulsions, synthesizing lignin-glyoxal prepolymer, an...
