Update of the Xylella spp. host plant database

EFSA Journal, Volume 16, Issue 9, September 2018., 2018
Abstract Following a request from the European Commission, EFSA periodically updates the database on the host plants of Xylella spp. While previous editions of the database (2015 and 2016) dealt with the species Xylella fastidiosa only, this database version addresses the whole genus Xylella, including therefore both species X.
