NAME OF THE ORGANISM: Claviceps purpurea (CLAVPU)
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: Cereals (including rice) sector
Is it justified that the pest is listed at a taxonomic rank below species level?
- Candidate: Cereals (including rice) sector
2 – Status in the EU:
Is this pest already a quarantine pest for the whole EU?
Presence in the EU:
Justification (if necessary):
The pest is present in Austria, Belgium, Bulgaria, Croatia, Czech Republic, Denmark, Finland, France, Germany, Greece, Hungary, Ireland, Italy, Lithuania, Netherlands, Poland, Portugal, Romania, Spain and Sweden (CABI, 2012).
HOST PLANT N°1: Sorghum x drummondii (SORSU) for the Cereals (including rice) sector.
Origin of the listing:
2 - Cereals sector: Council Directive 66/402/EEC
Plants for planting:
3 - Is the pest already listed in a PM4 standard on the concerned host plant?
4 - Are the listed plants for planting the main* pathway for the "pest/host/intended use" combination? (*: significant compared to others):
The plant species is not recorded as a host plant (CABI, 2012) (Australia, 2016). Experts confirmed that this species is not known to be a host plant.
CONCLUSION ON THE STATUS:
Disqualified: Sorghum x drummondii is not considered to be a host plant.
