Erwinia amylovora occurs in Portugal
In Portugal, the first incursion of Erwinia amylovora (EPPO A2 List) was observed in 2005 and subsequently eradicated. However, new outbreaks were reported in 2010/2011 in apple (Malus domestica) orchards in the municipalities of Alcobaça, Bombarral, Torres Vedras, Caldas da Rainha, Guarda, Viseu (all in Centro region), as well as in Ferreira do Alentejo and Alandroal (both in Alentejo region). Since then, official phytosanitary measures including intensive surveys and destruction of infected plants have been implemented to eradicate fireblight. In 2017, several outbreaks were detected in the areas listed below; in all cases infected plants have been destroyed:
