Potential of heartwood extracts as wood preservatives combined with linseed oil in 8-year above-ground and in-ground field trials
2024 - IRG/WP 24-20719
The current study assessed the efficacy of heartwood extracts from Tectona grandis, Dalbergia sissoo, Cedrus deodara, and Pinus roxburghii, combined with linseed oil, as protectants for two non-durable wood species against termites and decay fungi. Stakes measuring 45.7 × 1.9 × 1.9 cm and blocks measuring 12.5 × 3.75 × 2.5 cm of the sapwood of southern pine (Pinus sp.) and cottonwood (Populus ...

The potential of Wacapou (Vouacapoua americana) extracts to develop new biobased protective solutions for white woods
2024 - IRG/WP 24-20724
The valorisation of Amazonian wood residues into active chemical compounds could be an eco-friendly, cost effective and valuable way to develop wood preservatives formulations in order to enhance the decay and termite resistances of low durable wood species, by impregnation processes. Wacapou (Vouacapoua spp., Fabaceae) is a well-known Guianese wood species for its use in local wood construction ...

Changes in decay risk of wood in ground contact over Europe, from analysis of historic climate conditions
2024 - IRG/WP 24-41008
Changing climate conditions will affect global temperature and precipitation patterns, shifting some geographical areas into states that are more suitable for fungal wood decay. Climate normals, which are taken over a 30-year period, capture vast spatial and temporal variations in these conditions and comparing these can show changes over time. Importantly, being able to identify locations that ha...
