Referendum Passes to Continue the Pierce’s Disease Control Program

California Winegrape Growers Reaffirm Commitment to Vineyard Protection

SACRAMENTO, Calif. — The California Department of Food and Agriculture (CDFA) has officially certified the results of the Winegrape Grower Continuation Referendum for the Pierce’s Disease Control Program, with 76.56% of votes cast in favor, surpassing the minimum threshold required to continue this vital program.

The program, funded through a grower-paid assessment, supports critical research, monitoring, and rapid response efforts to combat Pierce’s Disease, its primary vector the glassy-winged sharpshooter, and other serious pest and disease threats.

“The strong vote in favor reflects the shared commitment of growers — large and small — to protect our vineyards and communities. This is one of the most effective, grower-driven pest and disease control programs in the country, and we sincerely thank every grower who cast a vote,” said Natalie Collins, president of the California Association of Winegrape Growers.

“Our wine community knows what’s at stake and recognizes that continued investment in the program is essential,” said Robert P. Koch, president and CEO of Wine Institute. “Protecting vineyard health is vital to the long-term success of California wine and the local economies it supports.”

“Growers stepped up to protect the future of California wine,” said Pete Downs, president of Family Winemakers of California. “We’re proud to stand with them in support of continued investment in research, rapid response and vineyard protection.”

A referendum is held every five years, with the next scheduled for 2030. The passed referendum renews the program through March 1, 2031, maintaining steady funding and oversight not only to combat the ongoing threat of Pierce’s Disease but also to address other critical pest and disease challenges. Its continuation reflects a strong, unified commitment to protecting California’s vineyards and sustaining the long-term health of the winegrape industry.
