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.
