Notice from the Ag Commissioner on GWSS Sighting in Residential Solano County

​On Friday, October 1, 2021 a total of five glassy-winged sharpshooters (GWSS) were confirmed on two different traps in a residential part of Vacaville, in Solano County. A delimitation survey that began on Saturday, October 2 confirmed some presence of GWSS at several more sites near the initial trap found through a visual survey. All of the finds so far have been in urban, residential settings in Solano County.
 
The Solano County Agricultural Commissioner’s office & the Pierce’s Disease Control Program are working together on next steps.  The Napa County Ag Commissioner’s office will share a press release and any relevant guidance as soon as available. Current protections in place in Napa County include:

• The Ag Department continues to inspect all incoming plant shipments from out of the county, regardless of the origin nursery and its location
• GWSS urban traps and nursery traps are placed throughout the county
• We track our landscape receiving locations and place GWSS traps up within days to additionally monitor for potential pests

 
NVG will continue to work with the Napa County Ag Commissioner’s office to keep growers informed as we learn more.
