N.D. Admin. Code 74-03-01-08
The production unit for certification shall be a field. No field or part of a field will be accepted unless field boundaries are clearly defined and properly isolated according to the specific crop standards. Isolation distances may be extended at the request of the seed commissioner for reasons including the production of transgenic crops or other kinds in proximity to fields being grown for the purpose of seed certification.
When it is necessary to remove a strip to obtain proper isolation, the part of the strip to be removed must be cut into the field to be inspected.
If two classes of the same variety are planted adjacent to one another in the same field, and field inspection has been applied for both, isolation may be accomplished by placing a flag at each end of the field ten feet [3.05 meters] into the higher class of seed, prior to inspection. The flags must be plainly visible at the time of inspection. The grower may harvest that isolated ten-foot [3.05-meter] section of crop with the lower class of seed.
