Neighborly Pest Management Working to Prevent Spread of Glassy-Winged Sharpshooter

The company is working with the Solano County Department of Agriculture to control the pest, which vector’s the bacterium that causes Pierce’s disease – a disease that kills grapevines.

SACRAMENTO, Calif. – An important part of the culture and economy in Solano County, Calif., and surrounding areas are the region’s grape vineyards and wineries. As such, the state has devoted resources to protecting vineyards from damaging pests, including the glassy-winged sharpshooter. The invasive pest is a leafhopper that vector’s the bacterium that causes Pierce’s disease – a disease that kills grapevines.
 
While the glassy-winged sharpshooter is established in Southern California, it is not in Northern California. The state’s Pierce’s Disease Control Program, working in cooperation with the Solano County Department of Agriculture, performs early detection pest surveys throughout the region. This monitoring, combined with a successful public awareness outreach program have helped keep the region mostly free of this pest. However, the glassy-winged sharpshooter has been periodically found in Solano County, most recently in 2004, and now in October.
 
“On October 1st, five glassy-winged sharpshooters were confirmed from detection traps in a residential area in Vacaville. Those finds triggered more extensive surveys to discern the extent of the infestation in preparation for eradication treatments,” said Ed King, agricultural commissioner, Solano County. 
 

The glassy-winged sharpshooter thrives on most landscaping plants and vegetation (e.g., citrus, jasmine and crape myrtle trees) so the concern is that they will become established on residential properties and then spread to nearby vineyards.

King said the first part of the Pierce’s disease control program is to saturate these residential properties with sticky traps to limit the extent of the infestation. Once this is accomplished, the next step is eradication efforts. 

After a formal bid process, the county selected Neighborly Pest Management, Sacramento, Calif. to perform the eradication. Neighborly had experience with the glassy-winged sharpshooter, having done this work the last time they were found in Solano County in 2004. 

Neighborly Owner Jim Steed said for this year’s treatment his company performed foliar treatments using Tempo Ultra SC. “It’s not a real heavy treatment. Right now, it is fall (in California) so we have to be careful with wind, but we are treating any host material that we can,” Steed said.

Prior to the application, the county will notify residents, and Steed said the goal is to treat homes where “finds” have been confirmed, as well as adjacent properties. “We’ve been treating 15-30 homes per days,” said Steed, who added that ag department officials are on site to witness the application. To date, Steed said Neighborly has treated about 60 homes.

During the next two months, King said, the Solano County Department of Agriculture will continue to monitor the treated areas and continue public outreach efforts to raise homeowner awareness about the glassy-winged sharpshooter.

Steed added that it’s been gratifying for him and his team to be involved in these eradication efforts. “The pest control that we perform everyday plays an important part in public health but this project also protects one of California's signature resources," he said. "We are thrilled to be a part of this project."
