2014 PD Research Symposium Highlights

The 2014 Pierce’s Disease (PD) Research Symposium held in Sacramento December 16-17 highlighted research progress and promising new products, technologies and mechanisms to prevent and control PD in grapevines. These include: traditionally-bred PD-resistant cultivars, the development of microbiological and transgenic mechanisms to suppress PD, and new directions to control PD’s vector–the glassy-winged sharpshooter (GWSS).

Two Board Members Set to Depart

Herb Schmidt and Pete Downs, two of the original members of the PD/GWSS Board, will soon be leaving their positions. Their commitment and dedication since the establishment of the Board have helped keep the grape industry alive and well in California.

“It’s the hard work and dedication of Board members like Pete and Herb that enables us to continue to succeed in our fight against Pierce’s disease and other pests and diseases of winegrapes,” said PDCP Statewide Coordinator Bob Wynn. “It was a privilege for the CDFA and PD/GWSS Board to have such valuable members contributing their time and expertise to helping protect California’s winegrape industry.”

GWSS Detection Program News

As part of protecting California from Pierce’s disease, the PDCP and county cooperators maintain a network of insect traps to actively monitor the state’s uninfested areas and rapidly detect any occurrences of glassy-winged sharpshooter (GWSS) in new areas. This monitoring effort is coordinated where possible with other ongoing insect detection activities, such as those for Asian citrus psyllid, to maximize the overall effectiveness of the pest detection effort. In recent months this ongoing vigilance netted five separate detections of GWSS in new areas. From late August through September, single GWSS were trapped in Lemoore (Kings County), Chowchilla (Madera County), and Dinuba, Tulare, and Visalia (Tulare County). In each case, the County Agricultural Commissioner’s office quickly responded to the finds by conducting visual surveys and placing additional traps around the find sites. In each case, no additional GWSS were found. These results show that the GWSS containment effort continues to be effective and that trapping and detection activities are important components in the statewide effort against Pierce’s disease and its vectors.

PD Symposium to Take the Year Off

A Pierce’s Disease Research Symposium will not be held in 2012. However, a proceedings-type document will still be prepared containing progress reports on current PD/GWSS research.

“This decision was based on many factors, including the maturity of the PD/GWSS research efforts and the need to allow field trials to continue to progress,” said Bob Wynn, PD Control Program Statewide Coordinator.

The next symposium is planned for 2013.

CDFA Announces 2012 Pierce’s Disease Assessment Rate

CDFA Announces 2012 Pierce’s Disease Assessment Rate

CDFA Secretary Karen Ross has set the Pierce’s disease winegrape assessment for the 2012 harvest at $1.00 per $1,000 of value, based on the recommendation made by the PD/GWSS Board at its June board meeting.

The assessment is used to fund research to find a solution to Pierce’s disease (PD), and other activities related to the transmittal of PD, a bacterial disease vectored by the glassy-winged sharpshooter that kills grapevines.

For more information about the PD/GWSS Board and how assessment funds have been used, visit www.pdgwss.net.
