2024 California Winegrape Pest and Disease Survey

For 25 years, the Pierce’s Disease Control Program (PDCP) has helped protect California vineyards through its statewide survey and detection programs, rapid response efforts, outreach and research on nine winegrape pests and diseases.

We want to hear directly from winegrape growers about the impact of pests and diseases, so we can better meet your needs. The survey findings will provide a data-driven foundation for more informed decision-making and strategic planning for the PDCP and your grower-led PD/GWSS Board.

Help shape the future of the program by sharing your perspective by Friday, Jan. 3. The survey will take about 10 minutes to complete.

Thank you!
