EU and IRL Plant health update (March 1st) by Teagasc’s Dónall Flanagan

In spite of the very cold weather, some changes in plant health regulation come into effect today.

In efforts to control the spread of the serious plant pathogen Xylella fastidiosa, new plant health control measures come in to force from today, March 1st. The following plants which are deemed of high risk of spreading Xylella fastidiosa must carry plant passports, be inspected and tested annually:

  1. Polygala myrtifolia
  2. Prunus dulcis
  3. Coffea,
  4. Olea europaea
  5. Lavandula dentata,
  6. Nerium oleander

Additionally, to support traceability, professional operators supplying or receiving any of these 6 plants must keep records of each lot supplied and who received it for 3 years.

If you had any of these plants growing on your nursery prior to March 1st, they will require inspection and testing before being sold. Please contact your local Department of Agriculture inspector to arrange.

Plant passports are required for plants which are hosts for Xylella fastidiosa. The EU Xylella host plant database can be checked regularly for updates. The most recent list is below with newest additions in bold.
