Pest categorisation of Elsinoë fawcettii and E. australis

EFSA Journal, Volume 15, Issue 12, December 2017., 2017
Abstract The Panel on Plant Health performed a pest categorisation of Elsinoë fawcettii and E. australis, the causal agents of citrus scab diseases, for the EU. The identities of the pests are well‐established and reliable methods exist for their detection/identification. The pests are listed in Annex IIAI of Directive 2000/29/EC as Elsinoë spp.
