Section 587.263 - Requirements for isolation1. Except as otherwise provided in subsections 2 and 3, the minimum distance a field of alfalfa must be from a different variety or a field of the same variety of alfalfa that does not meet the requirements for varietal purity for certification is: | Class Produced | Field of Less Than 5 Acres | Field of 5 Acres or More |
| | |
| Foundation | 900 feet | 600 feet |
| Registered | 450 feet | 300 feet |
| Certified | 165 feet | 165 feet |
2. Requirements for isolation for the certified class are based on the size of the field and the percentage of the field within 165 feet from another variety of alfalfa. If 10 percent or less of the certified field is within 165 feet, no isolation is required, but a definite separation must be maintained. If more than 10 percent of the field is within 165 feet, that part of the field must not be harvested as certified seed. The zone of isolation is calculated by multiplying the length of the common border with other varieties of alfalfa by the average width of the certified alfalfa field falling within the requirement of a distance of 165 feet isolation.3. The distance of isolation between classes of the same variety may be reduced to 10 feet, regardless of the class or size of a field.4. If a portion of a field meets the requirements for isolation, a clear line of demarcation must be established between the certified and noncertified portions of the field.Nev. Admin. Code § 587.263
