Grapevine yellows diseases caused by phytoplasmas are found in many areas of
the world where grapes are grown. Flavescence dorée
(FD) and Bois noir (BN) are two grapevine yellows
diseases that are considered quarantine pests in Canada because they can affect
crop yields of affected grapevines. There are no human health risks associated
with these pests.
BN and FD are commonly found in several
European countries. The first detection of one of these pests in Canada was the
confirmation of BN on a recently
imported grapevine in British Columbia during the Canadian Food Inspection
Agency’s 2006 routine surveillance program. An investigation into this
detection is underway.
