Results of the 2002 survey on Plum pox potyvirus in Canada
Plum pox potyvirus (PPV - EPPO A2 quarantine pest) was first found in Canada, in 2000, in limited areas of Ontario and Nova Scotia (see EPPO RS 2000/131). Since then, surveys and eradication measures have taken place in Canada. Results of the 2002 survey showed that the incidence of PPV is decreasing. In Ontario, all positive trees were located within existing quarantine areas. In the Niagara area, the number of positive samples was less in 2002 than in 2001. A small number of infected trees was detected in other isolated quarantine areas in Blenheim, Stoney Creek and Fonthill (PPV was no longer found in the Vittoria area). In Nova Scotia, as in 2001 PPV was no longer detected. PPV has never been found in British Columbia and Quebec fruit trees. In addition to orchards, PPV was not detected in all susceptible trees sampled as sources of budwood for propagation.
The situation of Plum pox potyvirus in Canada can be described as follows: Present, found in a few places in Ontario, no longer found in Nova Scotia, under eradication.
