Sorbus folgneri and Sorbus alnifolia: two new host plants of Erwinia amylovora

Characteristic symptoms of fireblight have been observed on Sorbus folgneri (Chinese montain ash) in the US National Arboretum in Washington DC (US), at the beginning of July 1994. Similar symptoms have also been observed on Sorbus alnifolia (Korean montain ash) in New Jersey. The bacteria isolated from these trees have been identified as Erwinia amylovora (EPPO A2 quarantine pest). This is the first report of fireblight on these two species of Sorbus.
