Oregon's Grape Pest & Disease Quarantine (OAR 503-052-0051) 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. As part of a multi-state harmonization project, the Oregon Department of Agriculture, Washington State Department of Agriculture, and the Idaho State Department of Agriculture worked closely with stakeholders in all three states to update their respective state quarantines based on current science, pest and disease pressures, and industry needs.

​More information about Washington's rulemaking efforts can be found on their Grape Pest Quarantine webpage. Washington's rule will be effective February 14, 2021.

Idaho adopted new rules for Grape Planting Stock and updated their quarantine in 2020. More information can be found on Idaho's Rules Governing Grape Planting Stock webpage.

​​This page contains information about Oregon's rulemaking process and will be updated with additional information and resources to assist importers of grapevines and grapes in complying with the quarantine rules.
