Regulated non-quarantine pest Project

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

NAME OF THE ORGANISM: Grapevine fanleaf virus (GFLV00)


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?

Is the pest defined at the species level or lower?:

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

  • Candidate: Vine sector
2 – Status in the EU:
Is this pest already a quarantine pest for the whole EU?

Presence in the EU:

List of countries (EPPO Global Database):
Austria (2000); Bulgaria (2000); Croatia (2000); Cyprus (2000); Czech Republic (2000); France (2000); Germany (2000); Greece (2000); Greece/Kriti (2000); Hungary (2000); Italy (2000); Italy/Sicilia (2000); Italy/Sardegna (2000); Malta (2000); Portugal (2000); Portugal/Azores (2000); Romania (2000); Slovakia (2000); Slovenia (2000); Spain (2000); Spain/Islas Canárias (2000)


Justification (if necessary):
Data of the presence of this pest on the EU territory are available in EPPO Global Database (

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?

Recommended for listing as an RNQP, based on EPPO PM 4 Standard.

8 - Tolerance level:

Is there a need to change the Tolerance level:

Proposed Tolerance levels:
Zero tolerance based on visual examination for the marketed plants, 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:

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 and other host plants for Arabis mosaic virus, 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.
