Grape Quarantine

Oregon's Grape Pest & Disease Quarantine (OAR 603-052-0051) establishes a quarantine for all areas of the United States and Oregon where harmful grape pests and plant diseases, as defined in this rule, are found.

All grapevine planting stock, including both potted and bareroot plants, cuttings, bench grafts, tissue culture plants, and seeds are covered by the quarantine. For more information, see the Oregon Grape Pest & Disease Quarantine Handout.

Vine mealybug (Planococcus ficus) in Oregon

Vine mealybug (VMB) was found in Oregon for the first time in summer 2021 by OSU Extension - male VMB were found in vineyards in Jackson County, OR. More information is available in the Vine mealybug Pest Alert Handout.  VMB is one of the most important pests in grape-growing regions and is a vector for leafroll viruses. Establishment and spread of VMB throughout Oregon's winegrowing regions would be a serious threat Oregon's wine industry.

What actions has ODA taken?

• Delimitation Surveys. In 2022 ODA conducted surveys to determine the extent of the infestation around the first two sites – 450 traps were placed on over 130 properties. It is currently believed that the infestation is contained to approximately 1.5 square miles around the initial finds. ODA will continue to trap in 2023 in Jackson County.
• Quarantine. Properties with grapevine plantings and positive trap finds were notified that they were under quarantine. Quarantine requirements and management recommendations were communicated. Vineyards applied at least one treatment in 2022.
  

Think you have found VMB or another mealybug in Oregon?

Report suspected finds in the reporting database. You will be asked to share the location and date of the observation, putative identification, and a photo if available.

Resources for mealybug identification

• Mealybug sampling protocols in English and Spanish. Note: these reference Gill's mealybug, but protocols are effective for VMB.

Oregon's Grape Pest & Disease Quarantine (OAR 603-052-0051)

The following pests and diseases are considered harmful organisms under Oregon's quarantine rules:

• Grapevine fanleaf virus
• Grapevine leaf roll-associated viruses
• Grapevine virus A
  **formerly Grapevine corky bark disease agent**
• Grapevine virus B
  **formerly Grapevine corky bark disease agent**
• Grapevine red blotch virus
• Grapevine phylloxera (Daktulosphaira vitifoliae, Viteus vitifoliae)
• Vine mealybug (Planococcus ficus)
• European grapevine moth (Lobesia botrana)
• Pierce’s Disease(Xylella fastidiosa)
• Fan-leaf virus nematode (Xiphinema index)

Certification Program Requirement - Effective January 1, 2023

In addition to other quarantine requirements, beginning January 1, 2023, all Vitis spp. plants and plant parts, including cuttings, bare-root plants, and rooted plants must originate from an approved certification program. Currently, California and Washington are the only approved programs. Phytosanitary certificates must accompany all shipments.

Notification Requirements for Importing Grapevine into Oregon

• Notification is required for all shipments of Vitisspp. plants and plant parts as described in OAR 603-054-0027.
• Recipients shall notify the department no later than two days after shipment arrival of the following information:
  • Number of grapevines, rootstocks, seeds, or softwood cuttings
  • Shipper's name and address
  • Consignee's name and address
  • Approximate date of delivery
  • Applicable copies of phytosanitary certificates and lab reports
• Ways to notify:
  • Email quarantine@oda.state.or.us
  • FAX 503.986.4564
  • Mail to Nursery Program, Oregon Department of Agriculture, 635 Capitol St NE, Salem, OR 97301

PPA 7721 Grapevine Pathogen Testing Project

ODA's Plant Health Program has funds available for testing of Vitis spp. planting materials for several quarantine pathogens of concern for grapevine. These pathogens include Xylella fastidiosa (Pierce's Disease), Grapevine red blotch virus, and Grapevine leaf roll-associated virus 3. These pathogens were identified as being of significant concern to Oregon's grape industries.

Funding for testing is available through a Plant Protection Act Section 7721 (PPA 7721) grant awarded to the ODA Plant Health Program. Funding is available for 2022 and 2023.

Pacific Northwest Grapevine Quarantine Harmonization Project

As part of a multi-state harmonization project, the Oregon Department of Agriculture (ODA), Washington State Department of Agriculture (WSDA), and the Idaho State Department of Agriculture (ISDA) worked closely with stakeholders in all three states to update their respective state quarantines based on current science, regional pest and disease pressures, and industry needs.

• ODA's updated quarantine rule was effective April 1, 2021.
