The September 5-6 show in Cheshire has sent an email to all exhibitors of plant material. APHA inspectors will be present at the show during build up to inspect all incoming nursery stock.

The email says that Xylella fastidiosa host plants are subject to the EU Plant Passporting scheme, therefore they should be accompanied by a ‘plant passport’ and particularly a plant passport number – which is often found on the plant label. 

If the plants do not have suitable labels attached, then an accompanying invoice or delivery note detailing plant Genus and species, number of plants and the plant passport number of the supplying nursery will also be sufficient, but must accompany the plants to the show and be made available by the exhibitor to an APHA inspector upon request.

Several more new hosts of Xylella have been added to the Plant Passporting regulations at the end of July.

Due to recent developments concerning the Xylella outbreaks in Italy, France and Spain, the UK trade is particularly concerned with the import of five very high risk hosts which have recently been prioritised by Defra policy: Polygala myrtifolia, Olea, Nerium, Lavandula and Rosmarinus.

Material of these high risk hosts originating from countries where outbreaks of the disease has been confirmed will be inspected closely by APHA inspectors in order to protect the Four Oaks Nursery production site, and other UK and EU production nurseries and exhibitors attending the show.

For exhibitor reference, the most up-to-date list of Xylella Outbreak Demarcated Areas (27th July 2017) which lists all affected provinces and municipalities where the outbreaks are under strict eradication measures can be found by clicking here.

The email includes a tree notification spreadsheet regarding plants that need to be pre-notified prior to their import from the EU (Prunus, Pinus, Quercus, Platanus, Castanea, Ulmus, Fraxinus). 

Exhibitors need to send it to  to make the notification on their behalf.

Exhibitors are reminded  that the UK has Protected Zones requiring additional Plant Passport statements for Quercus, Castanea and Platanus which can be carried on the label or accompanying delivery note.

Lastly, the message says that the UK has been consistently taking action against rising interceptions of Bemisia in recent years in support of the UK Protected Zone against this pest. Houseplant material of Nerium, Dipladenia/Mandevilla and Hibiscus rosa-sinensis has been particularly problematic and organisers urge all exhibitors to closely examine plant material of these and other hosts prior to their import to the UK or delivery to the show. As in previous years, plant material found infested with Bemisia tabaci will be subject to on-the-spot destruction by APHA inspectors.
