Overview

Red Blotch Symposium
Recent Advances in Grapevine Red Blotch Virus (GRBV) Vectors and Management

This symposium will provide a comprehensive update on research into all aspects of the grapevine red blotch virus and its impact on the wine industry by leading researchers in their respective fields. Topics will include an overview of the virus and progression, understanding the spread of red blotch disease and identifying the vectors and their biology, improved methods for tracking the disease remotely, mitigating the disease in the vineyard and understanding the impact of the disease on wine composition and sensorial attributes. The symposium promises to include practical advice to counter an insidious disease and will allow participants a chance to taste wines made from grapes infected with the disease as well as appropriate controls.

Symposium Chair: Anita Oberholster, University of California, Davis
