LBAM and what it means to the Napa County Producer

With the discovery of one Light Brown Apple Moth (Epiphyas postvittana) within
the Napa City limits, numerous regulatory changes have been imposed upon the
citizens and businesses of Napa County, including homeowners, farmers,
maintenance gardeners, retail and wholesale nurseries, field crops, and growers
of produce and cut flowers. In order to explain what is happening, we will
discuss the subject with regard to the location of the property.
Under this quarantine, the county is divided into two areas – the area under
quarantine, as defined by the California Department of Food and Agriculture, and
the rest of Napa County. The map of the area under quarantine is available at
the following website: http://www.cdfa.ca.gov/phpps/pdep/lbam-qmaps.pdf.
For all properties within the quarantine zone:
At the time of this writing, this area encompasses residential and agricultural
areas situated in an approximate 1.5 mile radius from the intersection of Highway
29 and Lincoln Avenue. We have approximately 17 retail or wholesale nurseries
and landscape holding yards, 2 certified producers, and about 15 wine grape
growers situated within this zone.
CDFA has written the quarantine language such that no produce, nursery stock,
cut flowers, fresh garlands or wreaths, green waste, or harvested commodities
may leave any property unless the owner of the above items has a compliance agreement with the Agricultural Commissioner. A compliance agreement is a
mutual, voluntary agreement of what each party (Ag Commissioner and the
business) agrees to do to enable the business to operate legally and to prevent
further spread of the pest.
For example, if you harvest your winegrapes and press them at a facility on the
same property, then you would not need a compliance agreement. But, if you
harvest and transport the grapes off-site, then you will need a compliance
agreement. In turn, if you are a receiver, you may also be subject to a
For all properties outside of the CDFA quarantine zone and within the boundaries
of Napa County:
Any business that produces the commodities listed above may move those commodities within Napa County. However, if they are taken into the quarantine zone, they must be processed or left there or protected from further infestation. If they are moved to another location, such as a winery within Napa County and outside the quarantine boundary, there is no requirement for a compliance agreement. However, if those commodities move outside the county boundary to another county, state, or country (such as winegrapes going to Oregon, certified producers selling produce or cut flowers in Solano County, or lavender buds going to Canada), a compliance agreement is required. Without the proper paperwork and inspections, other jurisdictions can reject or destroy your shipment.
What should you do?
Do not share produce unless you first process it. For example, pickle the olives or make the apple butter at your house. Then give it away.
Determine ahead of time whether you will have to have any of the above-mentioned commodities leave the quarantine area or the county. Contact the Agricultural Commissioner’s Office well in advance so that we can work with you
to issue the compliance agreement before you have to ship. For those grape growers who will be harvesting for sparkling wine, please contact us as soon as you read this article. Call our office at (707) 253-4357 and tell the receptionist that you need to get an LBAM compliance agreement. She will forward you on to someone who can assist you.
What will we do?
We will assess your situation and then assign a biologist to work with you to arrange for LBAM traps to be placed on your property and to write up the agreement.
At the time of this writing, there are eight other counties under quarantine regulation for LBAM: Marin, San Francisco, Contra Costa, Alameda, San Mateo, Santa Clara, Santa Cruz, and Monterey. If your business receives or transports regulated commodities from any of the infested counties, you may be required to have a compliance agreement. We can answer specific questions related to your business on a case-by-case basis. Call our office for more information.
