The PD/GWSS Board was established in July 2001 to support scientific research to find a cure for Pierce’s disease. An annual assessment paid by winegrape growers supports its research efforts. The PD/GWSS Board also advises the California Department of Food and Agriculture on a variety of other issues pertaining to Pierce’s disease and the glassy-winged sharpshooter.
The work of the Board is underlined by the fact that Pierce’s disease has no known cure and, left unchecked, could be devastating to the grape industry and several other California crops. A study released by the Wine Institute and the California Association of Winegrape Growers showed that the total annual economic impact of California’s winegrape industry is estimated at $51 billion.
