CPM issues

The Working Party was informed about the subjects discussed by the Commission for Phytosanitary Measures and by the Standards Committee.

The importance of improving pest reporting by EPPO members was emphasized and it was recommended that a questionnaire should be sent to EPPO countries to investigate the main difficulties in fulfilling the pest reporting obligations. It was also suggested that the EPPO Secretariat should investigate if it can be possible for EPPO members to provide pest reports to IPPC through EPPO on a voluntarily basis.

The Working Party also discussed potential new topics for ISPMs and it was agreed that a standard on “international movement of seeds” should be suggested given the importance of this trade, in particular to include elements on seed transmitted pests.



Strategic plan for 2010-2014

The Working Party broadly agreed with the proposed EPPO strategy for 2010-2014 and supported that work on PRA, information and documentation, and pest eradication and containment should receive a high priority.



Editorial policy of EPPO publications

Participants expressed their satisfaction with the EPPO website and information services which constitute a highly valued source of information in their NPPOs. Regarding the EPPO Bulletin, it was stressed that more articles should be published on eradication of pests  and on “lessons learned”.



Pest risk analysis

The Working Party reviewed the system established to perform PRA in the EPPO region and concluded that the Expert Working Groups for PRA should continue to operate on the basis of the current procedures. It highlighted the need for EPPO to perform more pathway analysis and recommended that ways to achieve this should be explored further. The Working Party confirmed that national PRAs can constitute a basis for EPPO recommendations and agreed that the guidelines to review national PRAs developed in 2008 should be used at the next Panel on phytosanitary measures and a report on the process presented. The Working Party established a list of pests for which PRA should be performed or evaluated in 2009-2010: Expert Working Groups for PRA should be organized in order of priority for Saperda candidaPhytophthora kernoviae (to broaden the UK PRA for the region), Epitrix spp., Phytophthora pinifolia, Tomato viroids and Halyomorpha halys.



Other issues

The Working Party discussed a proposed revision of PM 9/1(1) regarding a national regulatory control system for Bursaphelenchus xylophilus. It emphasized the importance of this revision but could not agree on the draft. It recommended that the Panel on quarantine pests for forestry should address the comments from the Working Party and that the outcome should be reported to the Council.


The Working Party discussed the initiation of new activities regarding diagnostics. Several Panels on diagnostics have identified a need to collect validation data for tests included in EPPO diagnostic protocols. The Working Party on Phytosanitary Regulations welcomed this initiative but noted that there should be a commitment of laboratories to provide such information.


Finally the Working Party discussed the situation of Chalara fraxinea, a pest increasingly observed in European countries on ash trees (Fraxinus excelsior) in the last ten years. The Working Party recommended organizing a Workshop in particular to discuss how to control this pest when found (e.g. good practice). This workshop is planned on 2010-07-01/02 in Norway.
