Nev. Admin. Code § 587.263 - Requirements for isolation
1. 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.
