The mission of the Pierce’s Disease Control Program (PDCP) is to minimize the statewide impact of Pierce's disease and its vectors in California.

Message About the Program

There was a time about 15 years ago when grape growers, vintners, researchers and regulators alike were, at the very least, unsure how severely Pierce’s disease and the glassy-winged sharpshooter would impact our precious viticultural resources.

Since August 1999, we’ve enjoyed many successful harvests, even in places like Temecula, where almost no one was willing to bet on the future of that region.

How has this been accomplished? Through a successful and cooperative partnership between federal, state, and local agricultural departments, university researchers, industry, growers, and the larger agricultural community.

The Pierce’s Disease Control Program continues to provide much needed protection to our valuable wine and grape industry and the economic activity it generates. We have every confidence that this ongoing effort will continue to build upon its successes until the job is done.
