CPM issues 

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

The Working Party discussed the interpretation of the term “Public Officer” by the FAO legal office and agreed on an EPPO position stating that it was not acceptable that such interpretation allows for issuance of phytosanitary certificates by private persons or companies. The Working Party drafted a paper for endorsement by the EPPO Council. 

The Working Party discussed the issue of recognition of pest-free areas to prepare discussion by experts in the IPPC Open-ended Working Group to undertake a Feasibility Study on the International Recognition of Pest Free Areas. Regarding ISPMs and EPPO Standards on the same subject, the Working Party agreed that the relevant EPPO Panels should be consulted to assess differences.



The Working Party reviewed the system established to perform PRA in the EPPO region and made suggestions for improving the procedure. The Working Party established a list of pests for which PRA should be performed or evaluated in 2009:
National PRAs produced by members for Diaphania indicaDiaphania perspectalis, and Phytophthora kernoviae should be evaluated by the Panel on Phytosanitary Measures.
Expert Working Groups for PRA should be organized for Tomato viroids, Meloidogyne minor and M. enterolobii, Leucinodes orbonalis, Hydrocotyle ranunculoides, Nysius huttoni, and Bactrocera invadens.


Other topics

The Working Party reviewed the progress report of the Panel on Alien Invasive Species and agreed with its work programme. It noted that some difficulties existed to make use of EPPO work on invasive alien plants at national level (e.g. in many countries a clear legal basis for NPPOs to be able to act is lacking, competences are often divided over different Ministries, NPPOs which have a role regarding invasive plants lack resources and specific expertise, support from research is very limited).

The Working Party was informed of all standards being developed by the Organization. The following draft standards were recommended for country consultation: 
Guidelines for development of a code of conduct on horticulture and invasive alien plants (new PM 3)
National regulatory control system for Eichhornia crassipes (new PM 9)
The situation of wheat stem rust Ug99 (a strain of Puccinia graminis f.sp. tritici) was considered, and it was concluded considering its dispersal mechanisms, that quarantine measures were not adequate to stop the spread of stem rust. The Global Rust Initiative is coordinating action against this pathogen.
