Premature failure of utility poles in Switzerland and Germany related to wood decay basidiomycetes

Abstract: In contact with soil, copper (Cu) formulations as preservatives are expected to inhibit wood decay by fungi and other soil-borne microorganisms. However, Cu-resistant brown-rot (BR) fungi lead to premature failures of utility poles at some sites. In this study, the service lives of 111 utility poles of Norway spruce (Picea abies (L.) H. Karst) (73 from Switzerland and 38 from Germany) impregnated with Cu-based wood preservatives were investigated. Three segments of each utility pole were analyzed. The severity… Show more

“…Antrodia serialis was selected as it is the most common fungus isolated from infected wood utility poles in Switzerland and Germany [3]. Serpula himantioides was selected due to its strong decomposition rates observed in 0.1% Cu-treated wood (higher than 5% mass loss after 8 weeks) [3]. R .…”

“…Copper (Cu) is the primary biocide component presently used to protect wood against soft-rot fungi in ground contact [1], but fails to protect against a range wood destroying basidiomycetes [2, 3]. Diverse mechanisms involved in the Cu-tolerance process of basidiomycetes have been described such as the ability to absorb Cu into cell wall components, extracellular chelation by metabolites and intracellular complexion with metallothioneins [4–9].…”
