Correct Bayer codes
The EPPO Secretariat is proposing to Bayer AG that the codes used in the EPPO plant quarantine information system PQR for the quarantine pests of the A1 and A2 lists, and of Annexes I and II of Directive 77/93, should be added to the Bayer lists, in the few cases where they are not already there. These codes are already cited in "Quarantine Pests for Europe". In checking these proposals, it was found that EPPO had used the codes PSDMPS for Pseudomonas syringae pv. persicae and XYLLFA for Xylella fastidiosa, but that Bayer had in the meantime assigned the codes PSDMPE and XYLEFA. These are the correct codes for these pests, and will be used in the next release of PQR (after the recently released version 3.0). Note that the EPPO coding system for viruses and MLOs is, in any case, still not harmonized with the Bayer lists. Discussions are under way on this.
