The Oregon Seed Certification Service provides a service to the public for the maintenance and increase of quality seed and propagating material. The service is provided to insure varietal purity and seed quality through review and retention of crop production records and a series of field and laboratory evaluations.

Legislative action taken in 1937 authorized and required the Dean of the College of Agricultural Sciences at Oregon State University to initiate a program for certification of seed in Oregon. This responsibility has been carried out by the establishment of the Oregon Seed Certification Service, part of the Extension Service and the Department of Crop and Soil Science at Oregon State University.

Scope of the Program

The Oregon Seed Certification Service certifies approximately 250,000 acres of seed crops annually. This acreage represents 50 different crop species. There are approximately 2500 seed growers, 382 seed warehouses and 237 contractors involved in the Oregon Seed Certification process. Detailed current information is available in the Special Reports section of the OSCS website.


The Oregon Seed Certification Service is funded by fees paid by participants in the program. Fees are assessed on the acres entered in the program, and the pounds of seed sampled for final certification evaluation. Specific costs can be found on the OSCS website under Fees and Deadlines.


The Oregon Seed Certification Service is available to the public on a voluntary basis. The application forms and requests for certification may be filed online at http://web.oscs.orst.edu/online/ or through the Oregon State University Extension Service in the county office where the crop is grown.

Specific standards for certification are available through each county Extension office, and are available in the Crop Standards section of the OSCS website.
