Natural infection of Fraxinus excelsior seeds by Chalara fraxinea
Forest Pathology 43 (1), 83-85
Abstract: The occurrence of Chalara fraxinea, the fungus responsible for dieback of European ash (Fraxinus excelsior), was investigated in the current and previous seed years collected from symptomatic trees in Latvia and Sweden using molecular techniques (DNA extraction, ITS-PCR, Sanger sequencing). Molecular analysis of seeds revealed the presence of 30 different fungal taxa. Chalara fraxinea was detected in 8.3% of seeds tested from the current year originating from Latvia. The presence of C. fraxinea in seeds of F. excelsior is of great concern to phytosanitary protection authorities in countries outside the current zone of infestation.
