STANDARDS FOR CERTIFICATION OF GRASS SEED
Section 587.323 - Requirements for isolation
Current through September 16, 2024
1. Except as otherwise provided in subsection 2, the following requirements for isolation must be met if at least two different strains of the same species of grass are in bloom at the same time:
| Type of Reproduction | Border to Be Removed | Minimum Isolation | |||
| Foundation | Registered | Certified | |||
| Cross-pollinated................................ | 0 feet | 900 feet | 300 feet | 165 feet | |
| 9 feet | 600 feet | 225 feet | 100 feet | ||
| 15 feet | 450 feet | 50 feet | 75 feet | ||
| Strains at least 80 percent apomictic and highly self-fertile species...... | 0 feet 9 feet | 60 feet 30 feet | 30 feet 15 feet | 15 feet 15 feet | |
2. If different classes of the same variety, which must also meet certification requirements, are being grown on the same or adjacent fields, the requirement for isolation may be reduced to 25 percent of that shown in the table in subsection 1. The minimum isolation for all seed classes of tetraploids is at least 15 feet from diploids of the same species.
3. Border removal is allowed only in fields of at least 5 acres. A border must not be removed until pollination of the crop to be certified is completed. The distance is the minimum isolation required for each class of seed after border removal.
4. For the purposes of this section, varieties within species with both cross-pollinated and apomictic type of reproduction are considered highly apomictic for minimum isolation unless otherwise specified for that variety.
