Pest and pathogen diagnosis is an essential part of the plant health support for SEERAD and is the basis of much of the plant health advice given. |
|
Quarantine and other pests and pathogens are diagnosed:
-
in traded plants (imported, exported and passported plants) and other material. Organisms for which surveillance is done include pepino mosaic virus on tomato (above), Bemisia tabaci on Poinsettia plants and Meloidogyne chitwoodii on potatoes;
-
-
for SEERAD certification schemes (potatoes, soft fruit and bulbs);
-
for specific surveys, including annual surveys for potato brown rot (Ralstonia solanacearum) and potato ring rot (Clavibacter michiganensis subsp. sepedonicus) as required in the EC Brown Rot Control Directive (98/57/EC as amended) and the EC Ring Rot Control Directive (93,85/EEC as amended);
-
to meet plant health requirements, such as pest freedom for PSTVd (potato spindle tuber viroid), and to meet the requirements of the EC PCN Directive (69/465/EEC) and EC Wart Disease Directive (69/464/EEC). See the
PCN
part of this web site for details of the sampling and testing for PCN in Scotland to meet seed potato certification requirements. Samples from SEERAD inspectors are examined for pests and pathogens using microscopic, microbiological, serological, molecular, electron microscopic and bioassay methods. SASA collaborates internationally to introduce and develop new techniques for the diagnosis of quarantine and other harmful organisms and is involved with EC evaluation of existing and new methods (see the research page). |
