Fire blight: first report in Latium, Italy.


In October 2012, during the official monitoring made by the regional Plant Protection Service, a diseased sample was collected in a nursery in Viterbo province (Latium, central Italy) from a quince plant showing shoot tips withered in the typical 'shepherd's crook', blackish-brown discolouration of the cortex which, when removed, disclosed the typical red streaks. The causal pathogen was identified as Erwinia amylovora based on genetic and pathogenicity analyses. This is thought to be the first report of fire blight caused by E. amylovora in Latium, Italy.
