Survey on grapevine viruses in Canada

A survey has recently been carried out in Canada on the following grapevine viruses : arabis mosaic nepovirus (EU Annex II/A2), grapevine fanleaf nepovirus and grapevine leafroll associated closteroviruses I and III. More than 12,000 acres were surveyed, accounting for over 82 % of the total grapevine acreage in Canada. The results showed that all these viruses were detected in the grape-producing regions in British Columbia, Ontario, Quebec and Nova Scotia. These viruses will no longer be considered as quarantine pests, and the industry now supports a certification program.
