"Focus on Potato" of the Plant Management Network has published a new webscast: "The Changing Face of Potato Virus Y" by Dr. Steward Gray of USDA-ARS.

This presentation will help growers, seed certification and regulatory officials, consultants and other practitioners in the U.S. understand how and why Potato Virus Y (PVY) is affecting the seed potato crop-and if left unchecked why it will become a major disease issue for the food sector of the potato industry.

Specific items covered include the reemergence of PVY as a disease problem in seed potatoes; how regulatory, business and science-based activities have addressed the problem; and finally what steps can and are being taken to manage the disease and prevent the newly introduced tuber necrotic strains of the virus from becoming a major quality issue for potato growers.

By the end of this presentation, the practitioner should understand the emerging PVY problem and know more about the existing and developing strategies that seed certification programs and growers, especially seed growers, can use to control PVY.

This webcast can be accessed without subscription until October 31, 2010.
