California’s Wine Industry the Big Winner in PD/GWSS Referendum


PD GWSSSacramento, Calif., June 18, 2015 – California’s winegrape growers voted overwhelming to continue the assessment on winegrapes to fund research on Pierce’s disease and other pests and diseases that threaten California’s winegrapes.

The vote was 83.44 percent in favor of continuing the assessment on winegrapes, which is currently set at 75 cents on every thousand dollars of value, until March 2021.

Wine Institute’s President and CEO Bobby Koch said, “The continuation of the research program is vitally important to combat Pierce’s Disease, other pests and diseases and helps ensure that full funding for the contain and control measures by USDA will continue.”

The PD/GWSS winegrape assessment was created in 2001 in response to the threat posed by the invasive glassy-winged sharpshooter spreading PD, which has no cure and kills grapevines. PD wiped out nearly 60 percent of the vineyards in Temecula in just two years and threatened to do the same to vineyards across California. The assessment has raised millions of dollars to fund research into finding solutions for PD, as well as address other new and emerging threats to vineyards.

“Passage of the PD referendum shows the unflagging commitment by growers, large and small, to protect their vineyards.  Fostering ongoing cooperation between industry, the state and the federal government is a proven formula to provide time to bring a long-term solution into play,” said Family Winemakers of California President Paul Kronenberg.

“A key lesson learned from our meetings on Capitol Hill and at the U.S. Department of Agriculture is that continued federal funding of the PD Control Program in California rests in large part on the industry’s continued commitment to pay the PD assessment. The renewal of the assessment sends a clear message to Washington that California’s winegrape growers are committed to finding a solution to PD,” said California Association of Winegrape Growers (CAWG) President John Aguirre.

With passage of the last referendum in 2010, the PD/GWSS Board was given the authority to designate other pests and diseases detrimental to winegrapes and vines for research funding. Since then the Board has designated the European grapevine moth (EGVM), red blotch (GRBaV), vine mealybug (VMB) and brown marmorated stink bug (BMSB) as serious threats to winegrapes.
