NAME OF THE ORGANISM: Plenodomus tracheiphilus (Phoma tracheiphila) (DEUTTR)


GENERAL INFORMATION ON THE PEST

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

Pest category:
 
Fungi


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?
 
Yes

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

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

Conclusion:
 
  • Candidate: Fruits (including hops) sector
2 – Status in the EU:
 
Is this pest already a quarantine pest for the whole EU?
 
No

Presence in the EU:
 
Yes

List of countries (EPPO Global Database):
 
Cyprus (2011); France (2011); France/Corse (2011); Greece (2015); Greece/Kriti (1994); Italy (2014); Italy/Sicilia (2011); Italy/Sardegna (1994)

Conclusion:
 
candidate

Justification (if necessary):
 
Data of the presence of this pest on the EU territory are available in EPPO Global Database (https://gd.eppo.int/).

HOST PLANT N°1: Poncirus hybrids (PMIHY) for the Fruits (including hops) sector.


Origin of the listing:
 
IIA2AWG

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?
 
Yes
 
Conclusion:
 
Qualified

 
Justification (if necessary):
 
Production of certified pathogen-tested trees and rootstocks of Citrus, Poncirus, Fortunella and their hybrids are covered by EPPO PM 4/12 (1) Standard.


CONCLUSION ON THE STATUS:
 
Recommended for listing as an RNQP, based on EPPO PM 4 Standard.


8 - Tolerance level:

Is there a need to change the Tolerance level:
 
No

Proposed Tolerance levels:
 
Zero tolerance based on visual examination.

9 - Risk management measures:

Is there a need to change the Risk management measure:
 
Yes

Proposed Risk management measure:
 
Non-certified material (‘CAC’):
(a) Plants produced in areas known to be free from Plenodomus tracheiphilus;
or
(b) Site of production found free from Plenodomus tracheiphilus over the last complete growing season, by visual inspection at least twice at appropriate times during the last growing season, and any symptomatic plants in the immediate vicinity rogued out and destroyed immediately;
or
(c) No more than 2% of plants in the lot showing symptoms during inspections at least twice at appropriate times during the last growing season, and those plants and any symptomatic plants in the immediate vicinity rogued out and destroyed immediately.

Pre-basic, basic and certified material, additional measures to be considered include:
• Physical protection of mother plants;
• Visual inspection of mother plants;
• Testing of pre-basic mother plants.
