Regulated non-quarantine pest Project

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




NAME OF THE ORGANISM: Burkholderia gladioli pv. gladioli (Pseudomonas gladioli) (PSDMGD)


GENERAL INFORMATION ON THE PEST

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

Pest category:
 
Bacteria


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: Vegetable propagating and planting material (other than seeds) sector
Is it justified that the pest is listed at a taxonomic rank below species level?
 
Yes

Conclusion:
 
  • Candidate: Vegetable propagating and planting material (other than seeds) sector
Justification (if necessary):
 
The species Burkholderia gladioli is sub-divided into two pathovars: pv. gladioli and pv. allicola and these pathovars are both specific to their hosts. As a consequence, a listing of this pest below the species level is justified.

2 – Status in the EU:
 
Is this pest already a quarantine pest for the whole EU?
 
No

Presence in the EU:
 
Yes

Conclusion:
 
candidate

Justification (if necessary):
 
The pest is present in Austria, Belgium, Czech repbulic, Finland, France, Germany, Italy, Netherlands and Romania (CABI, 2008).

HOST PLANT N°1: Allium porrum (ALLPO) for the Vegetable propagating and planting material (other than seeds) sector.


Origin of the listing:
 
RNQP Questionnaire

Plants for planting:
 
Plants intended for planting


3 - Is the pest already listed in a PM4 standard on the concerned host plant?
 
No
 
Conclusion:
 
Evaluation continues

4 - Are the listed plants for planting the main* pathway for the "pest/host/intended use" combination? (*: significant compared to others):
 
No
 
Conclusion:
 
Not candidate

 
Justification:
 
Allium porrum is not reported as a significant host and no references could be found during a literature search for Pseudomonas gladioli on A. porrum.


CONCLUSION ON THE STATUS:
 
Disqualified: Allium porrum is not reported as a significant host.


8 - Tolerance level:

Is there a need to change the Tolerance level:
 
No

Proposed Tolerance levels:
 
Not recommended for the RNQP status.

9 - Risk management measures:

Is there a need to change the Risk management measure:
 
No

Proposed Risk management measure:
 
Not recommended for the RNQP status.
