Phytophthora ramorum regulations for nursery growers
Phytophthora ramorum is a serious pathogen of many ornamental and native plants grown in Oregon. The regulations described in this section have been designed to help prevent the spread of this pathogen. All Oregon nurseries should take the regulations very seriously. If your nursery is found with Phytophthora ramorum plant material, the USDA and the ODA will work with you to meet all regulations, to eliminate the pathogen from your nursery, and to limit its spread to other nurseries.
Many details of regulations discussed in this section will change frequently. Please revisit website references regularly to obtain the most current information.
Regulations are designed to assure that nursery stock is free of Phytophthora ramorum.
