The Oregon Department of Agriculture Plant Health Program ensures the production of various virus-tested plants by Oregon nurseries that meet the regulatory requirements of domestic and international markets. We administer a voluntary virus certification program (OAR 603-051-0855 to 603-051-0859) and provide nursery audits, inspections, and pathogen testing for the industry.
What nursery stock do we certify?
The program certifies
ornamental and fruit trees as rootstock, interstock, or top-stock, including:
- Malus (apples and crabapples)
- Prunus (fruiting and ornamental cherries, plums, peaches, apricots, and almonds)
- Pyrus (domestic, Asian, and flowering pears)
- Cydonia and Chaenomeles (quince and flowering quince)
Plant Health also provides
official testing for blueberry (Vaccinium spp.) nursery stock at the request of growers to meet interstate quarantine rules.
