The National Clean Plant Network for Grapes (NCPN-G) was established to improve the health and productivity of wine, juice, and table grape vineyards in the United States. Clean grapevines are the key to higher yields, higher quality fruit, and cost-effective, sustainable grape production. The five centers in the network represent grape growing regions across the country.
In March 2016, a weekly webinar series entitled NCPN Webinar Series: Clean Plants for the Future of the Eastern Wine and Grape Industry was hosted by Dr. Tim Martinson, Senior Extension Associate for Cornell University's Viticulture and Enology program. The subject was how the efforts of the National Clean Plant Network, new testing protocols, and a revitalized New York certification program will reduce the risk of nursery-transmitted viral pathogens. The series featured different speakers each week and was attended by people from across the U.S. as well as internationally. Presentations are posted at
