First report of the Phytophthora disease of alder in Hungary
In summer 1999, alder trees (Alnus glutinosa) showing crown dieback, lower trunk lesions and tarry exudates were observed in a forest in northwest Hungary. An unusual Phytophthora related to P. cambivora was isolated from diseased trees and surrounding soil. Comparison with alder Phytophthora isolates from other countries showed that Hungarian isolates presented similarities either with isolates from Sweden or from United Kingdom. This is the first report of the Phytophthora disease of alder (EPPO Alert List) in Hungary. The situation of Phytophthora disease of alder in Hungary can be described as: Present: only in the northwest.
