Regulated non-quarantine pest Project

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




NAME OF THE ORGANISM: Alfalfa mosaic virus (Alfalfa mosaic alfamovirus) (AMV000)


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
Is it justified that the pest is listed at a taxonomic rank below species level?
 
Not relevant

Conclusion:
 
  • Not evaluated: Seed potato 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):
 
Austria (2002); Belgium (1969); Bulgaria (1993); Cyprus (2002); Czech Republic (1993); Denmark (1969); Finland (2002); France (2002); Germany (1993); Greece (1969); Hungary (1992); Ireland (2002); Italy (1993); Lithuania (2002); Netherlands (1993); Poland (1969); Portugal (2002); Romania (1969); Slovakia (2002); Slovenia (2002); Spain (2002); United Kingdom (1993); United Kingdom/England (1969); United Kingdom/Northern Ireland (1994); United Kingdom/Scotland (1969)

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: Solanum tuberosum (SOLTU) for the Seed potato sector.


Origin of the listing:
 
PM 4/28 (1)

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


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

 
Justification (if necessary):
 
Experts agreed that the nuclear stock should be tested or derived from mother plants which have been tested for this virus.


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


8 - Tolerance level:

Is there a need to change the Tolerance level:
 
Yes

Proposed Tolerance levels:
 
Zero tolerance, only for nuclear stock.

9 - Risk management measures:

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

Proposed Risk management measure:
 
Nuclear stock should be tested or derived from mother plants which have been tested for Alfalfa mosaic virus.
