Pierce’s Disease Research Symposium

Every year, leading researchers, winegrape growers and other wine industry professionals gather to share and discuss recent advances and discoveries for Pierce’s disease, the glassy-winged sharpshooter, and other designated pests and diseases of winegrapes. The two-day program includes research talks, grower presentations, and roundtable discussions.

The next Pierce’s Disease Research Symposium will be held in December 2022. Please check back for more information.
