The general standards as adopted in this chapter are basic and apply to small grain.\n\nB. Land requirements. A crop of small grain will not be eligible for certification if planted on land on which a small grain crop was grown the year previous except a crop of the same variety grown from certified seed.\n\nIn fields double-cropped, neither or the two crops grown in the previous calendar year shall have been the same kind as the crop being inspected, unless they were grown from a class of certified seed of the same variety.\n\nC. Field standards.\n\n1. Field inspection. At least one field inspection shall be made after the crop is fully headed when varietal or crop mixtures can best be determined.\n\n2. Isolation.\n\na. Wheat, oats, barley, triticale. A field shall be separated by a strip of ground adequate to prevent mechanical mixtures. The strip may be either mowed, uncropped or planted to some crop than the kind being certified.\n\nb. Rye. All rye fields used for the production of certified seed shall be isolated by at least 220 yards from the fields of any other variety or varieties of rye or fields of the same variety that do not meet the varietal purity requirements for certification. Isolation between diploid and tetraploid rye shall be at least 15 feet.\n\n3.
