Regulated non-quarantine pest Project

An EU funded project for the benefit of the whole EPPO region

NAME OF THE ORGANISM: Erwinia amylovora (ERWIAM)


Name as submitted in the project specification (if different to the preferred name):

Pest category:

1- Identity of the pest/Level of taxonomic listing:

Is the organism clearly a single taxonomic entity and can it be adequately distinguished from other entities of the same rank?

Is the pest defined at the species level or lower?:

Can listing of the pest at a taxonomic level higher than species be supported by scientific reasons or can species be identified within the taxonomic rank which are the (main) pests of concern?
  • Not relevant: Fruits (including hops) sector
Is it justified that the pest is listed at a taxonomic rank below species level?
Not relevant

  • Candidate: Fruits (including hops) sector
Justification (if necessary):
Fire blight has been described in nearly 200 plant species, mostly within the family Rosaceae, and within the subfamily Maloideae. The most frequent host genera are Chaenomeles, Cotoneaster, Crataegus, Cydonia, Eriobotrya, Malus, Mespilus, Pyrus, Photinia, Pyracantha, Sorbus and Stranvaesia (EFSA PLH, 2014). This is justified to continue the evaluation of E. amylovora on host plants listed at the genus level.

2 – Status in the EU:
Is this pest already a quarantine pest for the whole EU?

Presence in the EU:

List of countries (EPPO Global Database):
Austria (2014); Belgium (2015); Bulgaria (2012); Croatia (2007); Cyprus (1990); Czech Republic (2013); Denmark (1987); Estonia (2013); Finland (2014); France (2011); Germany (2013); Greece (2000); Greece/Kriti (1990); Hungary (2012); Ireland (2010); Italy (2013); Italy/Sicilia (1992); Latvia (2014); Lithuania (2010); Luxembourg (1984); Netherlands (2015); Poland (2001); Romania (2011); Slovakia (2005); Slovenia (2003); Spain (2016); Sweden (2008); United Kingdom (2014); United Kingdom/England (2014); United Kingdom/Northern Ireland (2014); United Kingdom/Scotland (2014)


Justification (if necessary):
Data of the presence of this pest on the EU territory are available in EPPO Global Database (

HOST PLANT N°1: Cydonia (1CYDG) for the Fruits (including hops) sector.

Origin of the listing:

Plants for planting:
Plants intended for planting, other than seeds

3 - Is the pest already listed in a PM4 standard on the concerned host plant?

Recommended for listing as an RNQP - based on EPPO PM 4 Standard.

8 - Tolerance level:

Is there a need to change the Tolerance level:

Proposed Tolerance levels:
Zero tolerance based on visual examination.

9 - Risk management measures:

Is there a need to change the Risk management measure:

Proposed Risk management measure:
The proposed measures are without prejudice to additional measures needed to provide the appropriate level of assurance in relation to plants moving into the protected zone or other areas where Erwinia amylovora is recognised as a quarantine organism:
- Non-certified material (‘CAC’):
(a) Plants produced in areas known to be free from Erwinia amylovora;
(b) The production site has been inspected at an appropriate time during the last growing season and plants showing symptoms, and any surrounding host plants, have been immediately rogued out and destroyed.

- Pre-basic, Basic, Certified material: Additional measures could include
• Isolation from host plants of Erwinia amylovora, or
• [where this is legally enforceable] Inspection of host plants in the immediate vicinity and removal and destruction of any symptomatic plants.
