S.C. Code Regs. 27-1002. Small Grain Certification Standards (Wheat, Oats, Barley, Rye, and Triticale)
I. Application of General Certification Standards
The General Certification Standards, Clemson University Regulation 27-190, are basic and applicable and together with the following specific standards constitute the standards for certification of small grains.
II. Land Requirements
A small grain crop shall be planted on land on which the last crop grown was of another crop kind other than small grains, or was planted with a class of certified seed of the same variety. A crop will not be eligible for certification if planted on land on which the same crop kind was grown the previous year, unless the previous crop was grown from a class of certified seed of the same variety.
III. Field Inspection
A field inspection shall be made after the crop has fully headed, but before harvest.
IV. Field Standards.
A. General
1. Unit of certification
The unit of certification shall be a field but a portion of a field may be approved provided the discarded portion can be harvested separately and is eliminated from certification.
2. Isolation
a. 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 other than the kind being certified.
b. Wheat for certification must be isolated from a field of rye by a distance of 660 feet.
c. All barley and wheat fields for the production of all classes of certified seed must be isolated by at least 990 feet from other fields which contain smut in excess of the tolerance indicated in the specific field standards.
d. A field producing any class of certified seed must be isolated by at least 660 feet from rye fields of any other variety or fields of the same variety that do not meet the varietal purity requirements of the class of seed inspected and are the same chromosome number. Isolation between diploid and tetraploid rye shall be at least 15 feet.
B. Specific
V. Seed Standards
VI. Size of Lots
VII. Size of Official Sample
A 2 lb. sample of small grains is required for official purity and germination tests by the S.C. State Department of Agriculture.
