What is Pierce's Disease?

Pierce's Disease is a bacterial infection, which is spread by bugs that feed on grapevines, particularly the "glassy winged sharpshooter." Grapevines that become infected with PD can quickly become sick and die.

  • Abstract: It is vital to the wine industry to be aware of the potential effects of control programs for disease, insects and other pests that might affect wildlife in riparian zones, as the health of these zones is important to properly functioning ecosystems as well as to the public and regulatory agencies. This study undertook to evaluate the effects on a variety of vertebrates of the removal of vegetation as well as planting of non-disease reservoir plants in riparian zones to control or reduce the incidence of Pierces disease. Studies were initiated in 1997 with the establishment of eight plots, three on Conn Creek (open, managed, and not managed), and three on the Napa River (Ecological Reserve, managed, and not managed) in Napa County, and two (managed and not managed) on Maacama Creek in Sonoma County.
