Grapevine Red Blotch Disease: An Emerging Issue

Wednesday, March 27, 2013 at 3:30pm to 5:00pm

Webinar hosted at Cornell

Grapevine red blotch disease was first identified in 2008 as a syndrome that affects fruit ripening.  Virologists in New York and California have identified a graft-transmissible virus, called Grapevine red blotch-associated virus (GRBaV) that is associated with the symptoms.  Infected vines have been identified in California, New York, Virginia, Maryland, Pennsylvania, Texas and Washington.


Join Cornell University virologist Marc Fuchs, University of California Cooperative Extension Farm Advisor Rhonda Smith, and University of California-Davis Foundation Plant Services director Deborah Golino for an informational session on red blotch disease.  We will describe the virus, its impact on vine health, what informal field observations have told us, and what measures are being taken to test and identify infected vines and planting material.
