NAME OF THE ORGANISM: Thanatephorus cucumeris (Black scurf) (RHIZSO)
GENERAL INFORMATION ON THE PEST
Name as submitted in the project specification (if different to the preferred name):
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: Seed potato sector
Is it justified that the pest is listed at a taxonomic rank below species level?
- Not evaluated: Seed potato sector
2 – Status in the EU:
Is this pest already a quarantine pest for the whole EU?
Presence in the EU:
HOST PLANT N°1: Solanum tuberosum (SOLTU) for the Seed potato sector.
Origin of the listing:
5 - Seed potato sector: Council Directive 2002/56/EC
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?
Justification (if necessary):
Listed in EPPO PM 4/28 Standard (table3) as Black scurf (Rhizoctonia solani).
CONCLUSION ON THE STATUS:
Recommended for listing as an RNQP, based on EPPO PM 4 Standard. The SEWG recalled that a range of symptoms can be caused on the crop, with different impacts, and this should be considered when using common names.
