Pierce's Disease Control Program

The Pierce's Disease Control Program slows the spread of the glassy-winged sharpshooter and minimizes the impact of Pierce's disease in California while sponsoring research and development for sustainable solutions to pests and diseases.

PDCP's core strategies to protect California winegrapes:

• Contain the Spread: Prevent the spread of glassy-winged sharpshooters to non-infested areas with nursery inspections, trapping, and treatment, bulk citrus inspections, area-wide treatment programs and biological control.
• Statewide Survey and Detection: Find new GWSS infestations and confirm that non-infested, at-risk areas remain free of infestation.
• Rapid Response: Respond quickly to detections of GWSS in new areas with surveying and treatments.
• Outreach: Raise awareness about Pierce's disease and its vectors.
• Research: Sponsor research and development for sustainable solutions to Pierce's disease and its vectors.
