EPPO RNQP

NAME OF THE ORGANISM: Arabis mosaic virus (ARMV00)

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: Vine sector

Is it justified that the pest is listed at a taxonomic rank below species level?

Not relevant

Conclusion:

Candidate: Vine sector

2 – Status in the EU:

Is this pest already a quarantine pest for the whole EU?

Presence in the EU:

Yes

List of countries (EPPO Global Database):

Austria (2014); Belgium (2007); Bulgaria (1995); Croatia (2012); Czech Republic (2007); Denmark (1993); Finland (2011); France (2000); Germany (2009); Hungary (2009); Ireland (1997); Italy (2007); Latvia (1990); Lithuania (2006); Luxembourg (1996); Netherlands (2015); Poland (2012); Romania (2011); Slovenia (1996); Spain (2011); Sweden (1993); United Kingdom (1996); United Kingdom/England (2002); United Kingdom/Northern Ireland (1984); United Kingdom/Scotland (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: Vitis (1VITG) for the Vine sector.

Origin of the listing:

Council Directive 68/193/EEC

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

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:

Yes

Proposed Tolerance levels:

Zero tolerance based on visual examination, and on testing stock nurseries for Pre-basic, Basic and Certified material. Experts also agreed to below the failure rate for nepoviruses from 10% to 5% for the non-certified material (within a 10 % overall limit for virus symptoms).

9 - Risk management measures:

Is there a need to change the Risk management measure:

Yes

Proposed Risk management measure:

Based on visual examination carried out at least twice during the last growing season at appropriate times for the expression of symptoms.
- Non-certified ('standard'): not more than 5% [reduced from current 10%] of plants showing symptoms of nepoviruses (Arabis mosaic virus, Grapevine fanleaf virus and Cherry leaf roll virus) and not more than 10% of plants showing any virus symptoms and all plants showing symptoms rogued out and destroyed within two weeks.
- Pre-basic (“initial”), Basic, Certified: additional measures (in addition to non-certified) could include an isolation distance from other vines, a periodic testing of mother plants, a soil testing for virus vector nematodes, and a rest period from host plants of the virus before planting.
