South Carolina Code of Regulations
Chapter 27 - CLEMSON UNIVERSITY STATE LIVESTOCK-POULTRY HEALTH COMMISSION
Article 14 - SEED CERTIFICATION STANDARDS
Section 27-1002 - Small Grain Certification Standards (Wheat, Oats, Barley, Rye, and Triticale)
Current through Register Vol. 48, No. 3, March 22, 2024
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.
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.
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.
