Apple moth quarantine extends in Bay Area counties

New discoveries of the light brown apple moth prompted state officials to expand the quarantine boundaries in Sonoma and Santa Clara counties.

A new quarantine of about 18 square miles is now established in the Sebastopol area of Sonoma County while an existing quarantine in the Milpitas area of Santa Clara County increased by about 64 square miles.

About 2,414 square miles are now under quarantine in California. State and federal quarantine regulations prohibit the movement of all nursery stock, all cut flowers and all host fruits and vegetables within or from the quarantined area unless it is certified as free from the pest by an agricultural official or is purchased at a retail outlet.

The highly destructive moth has not been found in the San Joaquin Valley, but trapping for it continues statewide. The moth is capable of harming more than 2,000 plants and more than 250 crops.
