NAME OF THE ORGANISM: Potato virus X (PVX000)


GENERAL INFORMATION ON THE PEST

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

Pest category:
 
Viruses and viroids


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: Seed potato sector, Vegetable propagating and planting material (other than seeds) sector
Is it justified that the pest is listed at a taxonomic rank below species level?
 
Not relevant

Conclusion:
 
  • Not evaluated: Seed potato sector, Vegetable propagating and planting material (other than seeds) sector
2 – Status in the EU:
 
Is this pest already a quarantine pest for the whole EU?
 

Presence in the EU:
 

Conclusion:
 

HOST PLANT N°1: Solanum lycopersicum (LYPES) for the Vegetable propagating and planting material (other than seeds) sector.


CONCLUSION ON THE STATUS:
 
Not evaluated: This pest/host combination was not identified by any EU MS in the RNQP Questionnaire as requiring a revision of current thresholds and or a revision of current management measures. This pest/host combination was not identified by the experts of the vegetable SEWG as being a candidate for the RNQP Status with specific tolerance levels and/or specific risk management measures. Experts recommended that this pest/host combination should be covered in the future by the 'substantially free from' requirement that will remain in the Vegetable propagating and planting (excluding seeds) EU Marketing Directives.


HOST PLANT N°2: Solanum tuberosum (SOLTU) for the Seed potato sector.


Origin of the listing:
 
5 - Seed potato sector: Council Directives 2002/56/EC, 2014/20/EU and 2014/21/EU

Plants for planting:
 
Plants intended for planting, other than [true] seeds


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


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:
 

9 - Risk management measures:

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

Proposed Risk management measure:
