Subject: Tests confirm Potato mop-top virus in Nova Scotia's Annapolis Valley
Date posted: January 10, 2003

Tests conducted in October 2002 throughout Nova Scotia’s Annapolis Valley confirmed the presence of Potato mop-top virus (PMTV). This is the second outbreak of PMTV in Canada and has prompted additional management negotiations for seed certification between the United States and Canada. Infected potatoes can be consumed but infested land could be forced out of potato production for 10 or more years due to the longevity of the PMTV's fungal vector Spongospora subterranea even in the absence of a host. PMTV is found in Asia, Europe, and in North and South America.
