Afternoon Brief: Legislation Signed to Extend Pierce’s Disease Control Program

This week, Governor Newsom signed AB 1861 to extend a vital program within the California Department of Food and Agriculture that protects Californias vineyards and iconic wine industry from pests and disease

In the 1880s, Pierce’s disease caused a devastating, total collapse of the Southern California grapevine industry. Today, growers have hope for the future thanks to new varieties. Adam Tolmach, owner of Ojai Vineyard, planted four of these new varieties as a field trial on a plot of land where Pierce's disease wiped out his grapes in 1995.  Pierce’s disease is a bacterium spread by insects, typically a sharpshooter. One bite and the vine dies within two to three years. To develop resistant varieties, Andy Walker of the University of California at Davis crossed the European grape Vitis vinifera with Vitis arizonica. 20 years later, commercial growers have access to three red and two white varieties. Listen in to learn how Tolmach’s experiment is a success both in the vineyard and with customers. Plus get tasting notes for the new varieties.
