Thirty-seven new plant species have been identified as hosts of the Xylella fastidiosa pathogen. Most were naturally (not artificially) infected and were found both in EU countries (France, Italy, Portugal and Spain) and non-EU countries (USA and Iran). The new hosts include common ornamental, wild and commercial plants such as fleabane (Erigeron sp.), Helichrysum stoechas, pistachio (Pistacia vera), and persimmon (Diospyros kaki).
The newly identified hosts are included in the latest update of EFSA’s database of plants that act as hosts for X. fastidiosa. The list now comprises 595 plant species; for 343 of the species, infection has been identified by at least two detection methods under natural or experimental conditions.
