First report of Chalara fraxinea in Hungary
In Hungary, symptoms of ash dieback caused by Chalara fraxinea (EPPO Alert List) were observed on Fraxinus excelsior for the first time in May and June 2008, in two forest management units located in the north-west of the country. Symptoms were characterized by shoot wilting, necrotic bark lesions, dieback of young twigs (1 to 2-year old), and xylem discoloration. The pathogen was isolated and identified (morphological characteristics) and its pathogenicity was demonstrated by wound inoculation of shoots with fungal mycelium. This is the first report of C. fraxinea in Hungary.
The situation of Chalara fraxinea in Hungary can be described as follows: Present, first found in 2008 in the north-west.
