There has been a short-notice change in the schedule for VENSource wine industry seminars at UC Davis. A new seminar, Current Issues: An In-Depth Look at Red Leaf Viruses, will be held Friday, May 9, 2014, in Freeborn Hall on the UC Davis campus. I'm not a viticulturist or a plant pathologist so the subject is a bit outside my area of expertise, but it looks like a really good lineup of speakers.

Exerpted from the VENSource email:

Current Issues: An In-Depth Look at Red Leaf Viruses

Save the Date: Friday, May 9, 2014
Where: Freeborn Hall on the North Quad at UC Davis
Time: 9:00am to 3:45pm

If you work anywhere in the international wine industry, you are aware of the hottest topic in grapevine sustainability today: the rapid spread of the red leaf viruses. Case in point; look at the cover of the May 31 Wine Spectator…… looks like a beautiful fall vineyard in Chile to the untrained eye, but that same view appears differently to the vineyard/winery professional, who recognizes a more devastating possibility in those “fall” colors.

We, at the University of California, in collaboration with USDA researchers, have been at the forefront of the effort to better understand all aspects of the pathology and, ultimately, the effective control of the red-leaf virus diseases. To further our goal to extend the practical information we have gained from our research, we’ve brought together some of the most active experts in the field of red leaf viruses for this seminar. They’ll address how we can make the best decisions about dealing with the impact of these diseases, and the importance of cooperation between the University researchers, grape growers and their winery clients to gain a better understanding of the scope of these diseases in order to minimize the overall impact on the industry. We’ll leave time for your questions, so be sure you bring your concerns to these experts.

This is really a must-be-there event and we hope to see many of you at Freeborn on Friday, May 9, 2014 for a full day of discussion about how to deal with red-leaf virus diseases this season and beyond.
