EGVM Program Update 2015
In 2015, for a third straight year, no European Grapevine
Moths (EGVM) have been detected in traps deployed in Napa County. Continued cooperation by the winegrape
industry and local, state and federal departments of agriculture has
contributed to the success if the EGVM eradication program. In August 2014, southern areas of Napa County
were removed from the EGVM quarantine. See the quarantine map.
For 2015, 65 growers and vineyard management companies
treated 93 sites that were within 500 meters of a 2013 EGVM detection. This represented 1,900 acres of vineyards. Staff of the Napa County Agricultural
Commissioner’s Office conducted on-site verifications of these
applications. Growers operating within
the Napa County quarantine area followed sanitation practices and shipping
protocols required in compliance agreement exhibits. During harvest, Ag Commissioner staff
conducted compliance checks of both haulers and wineries to assess compliance
with cleanliness of bins and equipment as well as possession of required
compliance agreement documents.
If no moths are detected through the second flight of 2016,
the United States Department of Agriculture will likely lift the EGVM
quarantine for Napa County and the entire state. Currently a post eradication plan is being
formulated to address future EGVM trapping plans, continued education and
outreach strategies, as well as to develop a proactive plan to survey for and
detect other serious grape pests.
