NAME OF THE ORGANISM: Athelia rolfsii (Wet rot) (SCLORO)


GENERAL INFORMATION ON THE PEST

Name as submitted in the project specification (if different to the preferred name):
 
Wet rot

Pest category:
 
Fungi


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
Justification (if necessary):
 
According to IndexFungorum (http://www.indexfungorum.org/names/NamesRecord.asp?RecordID=219848) the preferred name is Athelia rolfsii rather than Sclerotium rolfsii.
