Abandoned or Neglected Vineyards

Vineyard properties that are neglected or not properly maintained often become reservoirs for populations of various pests and can potentially threaten neighboring production vineyards. A pest like European Grapevine Moth (Lobesia botrana) requires timely and specific treatments to control its populations, and it could thrive if allowed to exist in an untreated habitat. The combined efforts of the wine industry and grape growers would be undermined by abandoned and neglected vineyards which could serve as sources of future infestations.

If you become aware of such a vineyard, please contact the Napa County Agricultural Commissioner’s Office, and we will work to notify the property owner. If you are the owner of an abandoned vineyard, you need to mitigate the pest risks that exist, including making properly timed pesticide applications, removing flowers and fruits, or pulling the entire vineyard. Please contact our office for information on mitigation options. The Agricultural Commissioner has the legal authority to declare such an abandoned and neglected vineyard a nuisance and can compel the abatement of the threat at the owner’s expense.
