3rd Meeting of the EPPO Panel on Diagnostics in Mycology

Qawra, Malta, 2018-10-10/12

 

 

The Panel on Diagnostics in Mycology met on 2018-10-10/12 in Qawra, Malta at the kind invitation of the NPPO of Malta. The meeting was organized back to back with European Food Safety Authority (EFSA) Citrus Black Spot (CBS) Surveillance Workshop. Nineteen Panel members and 4 observers attended the main meeting.

 

 

 

 

New diagnostic protocols

Heterobasidion irregulare

The Panel was very grateful that one of the authors of the draft diagnostic protocol (developed in the framework of an EU funded project (EMPHASIS) could attend the meeting. The Panel went through the new Standard and most questions could be addressed by the author during the meeting. It was agreed that the final version should be sent for country consultation, along with the PM 9 National regulatory control system Standard on the same pest, after the meeting (both Standards were circulated in October and comments will be reviewed in early 2019).

 

 

 

Revised diagnostic protocols

Work is in progress on the revision of the following protocols:

 

Phyllosticta citricarpa (formerly Guignardia citricarpa)

The Panel was held following the European Food Safety Authority (EFSA) Citrus Black Spot (CBS) Surveillance Workshop and the Panel benefitted from the presence of 5 experts who attended the workshop were able to stay on for the first session of the Panel and give presentations on their work. A new version of the protocol will be prepared for a small drafting team (to include experts from Spain, Portugal and Malta). A potential Euphresco project on detection of this pest will be considered.

Fusarium circinatum (formerly Gibberella circinata)
