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.
A Pierce's Disease Research Symposium will not be held in 2017.
A collection of research progress reports, similar to the annual Proceedings, will be prepared and available in late December 2017.
