Grape Quarantine

California Grape Quarantine

The Oregon Department of Agriculture (ODA) updated its grape quarantine rules earlier this year to minimize the risk of dangerous invasive species coming into Oregon. The ODA has provided a letter for use by Oregon winemakers in communicating the requirements of the quarantine to California winegrowers prior to importing grapes.

In addition, Oregon winemakers must adhere to “control and eradication methods for harmful pests and diseases. Control and eradication methods used shall only be those approved by the Department and will be based on the best available science.” These methods my include composting of infected fruit.

Washington Grape Quarantine Compliance Agreement Set

The Oregon Department of Agriculture (ODA) and Washington State Agriculture Department (WSDA) officials have signed a compliance agreement designed to govern the rules of the quarantine against pests and diseases that was recently extended to include wine grapes. The agreement between Oregon and Washington will result in WSDA providing the ODA with a list of Washington growers exporting to Oregon and WDSA’s survey data on the Vine mealybug and European grapevine moth. Oregon buyers of  grapes will not be required to obtain phytosanitary certifications or undergo an inspection of their fruit.
