7.02.03 - Vascular wilt diseases
The aim of this Working Party is to promote international collaboration and increased contact among forest pathologists working on wilt diseases of forest trees. The working party has been inactive for several years, however, there is an increasing need to revive interest in this working group. Meetings of the Working Party are scheduled to take place at intervals between 2-4 years. Our wish is to create a relaxed atmosphere among colleagues working on these themes across the world in order to build up a strong group in which ideas could flow freely and where both young and senior researchers are motivated to take part.
Reports of new vascular wilt diseases of forest trees causing severe impact glogally have been increasing in recent years. Dutch elm disease, after more than 100 years from its first report, is still a serious problem in many natural woods and urban contexts but there are also emerging vascular wilt diseases such as rapid 'Ōhi'a death caused by two newly described Ceratocystis species in Hawaii. Laurel wilt and plane tree canker stain disease are spreading, threatening their hosts' natural ranges. Bacterial wilts of forest trees, are still an underestimated problem, e.g. Ralstonia solanacearum s.l. causing wilt in Eucalypts. Knowledge exchange and share of experiences are strongly needed to effectively contrast these pathogens at global level.
