VASCM: Pierce's Disease Report from the PDCP - eradication in Santa Clara Co.

[Mary Lindsay, Muns Vineyard]

Thank you to Greg Jenkins for forwarding the following December 
newsletter from the Pierce's Disease Control Program. The PDCP is under 
the California Dept. of Food & Ag, and you can find the website at 
http://www.cdfa.ca.gov/pdcp/ . 

Greg contacted the CDFA to find out more about "the eradication of GWSS 
infestations in Santa Clara County" mentioned in this newsletter, and 
has shared the reply, which is included at the bottom of this message. 
Just in case you didn't know that the GWSS had gotten this close.

If you are interested in receiving the PDCP newsletter, I would email 
pdcpinfo at cdfa.ca.gov <mailto:pdcpinfo at cdfa.ca.gov> and request it. I 
don't see a convenient link to it from the home page.

What We Do in the "Off Season"

The PDCP is a year-round program always working to protect California's 
vineyards from Pierce's disease. During the warmer months, the PDCP is 
kept busy with field activities, but when the weather cools down, 
there's still plenty to do.

The "off season" entails a great deal of work reviewing and updating 
protocols and informational materials, maintaining colonies of 
glassy-winged sharpshooters and parasitoids, conducting maintenance and 
repairs on equipment and facilities, planning and completing contracts, 
preparing the Annual Report to Legislature, soliciting and reviewing 
research proposals, and putting together the annual research symposium 
and proceedings.

The PDCP is working hard year-round. Learn more about the PDCP's "off 
season" work in the winter newsletter, coming soon.

GWSS Eradication Success
The GWSS infestations in the Branham and Evergreen areas of Santa Clara 
County were declared eradicated as of
December 2, 2010. This makes a total of four incipient infestations 
eradicated in Santa Clara County and 15 program wide since its inception.

2010 PD Research Symposium
The 10th annual PD Research Symposium took place December 16th and 17th 
in San Diego. The symposium welcomed 120 attendees each day to hear the 
latest in research from scientists around the world. Read more about the 
symposium in the upcoming winter newsletter.

Regulatory Nursery Program Update
>From January 1, 2010 through October 31, 2010, there were 49,960 nursery 
stock shipments from  GWSS-infested areas to non-infested areas of the 
state.
Year to date, six regulatory actions have been taken by destination 
(receiving) counties due to viable GWSS life stages being present. Each 
of these finds resulted in the issuance of a Notice of Rejection.

Hello Greg,
 
Thank you for your inquiry into the recent eradications of the 
glassy-winged sharpshooter (GWSS) in Santa Clara County.
 
GWSS was first detected in the Branham area on a trap in 2001.  The most 
recent GWSS find was in August 2007.  Foliar and systemic ground 
treatments were conducted on and around the infested properties with the 
insecticide Merit.  These treatments decreased GWSS populations 
significantly. GWSS was found on only six properties in 2006 and 2007.
 
GWSS was first trapped in the Evergreen area in July 2006.  After foliar 
and systemic ground treatments were done using the insecticide Merit in 
2006, GWSS was found on only three additional properties through 2007 
and 2008.  
 
We work cooperatively with the Santa Clara County Agricultural 
Commissioner's office who administers the Pierce's Disease Control 
Program in the county.  Thorough monitoring of traps and surveys by the 
Agricultural Commissioner's office the last few years revealed no 
additional GWSS in the two areas and we were able to declare these two 
areas eradicated.
 
Let me know if you have any additional questions.
 
Thank you & Happy Holidays.
