Field standards

1. Isolation. a. Prior to flowering and inspection, the field must be isolated from fields of any other variety or fields of the same variety not meeting genetic purity requirements for certification. b. The minimum isolation distances required between inspected hemp and other hemp crops must be maintained as specified in the following table. There must be no hemp plants within three hundred feet [91.44 meters] of a seed field and no more than four plants per acre outside three hundred feet [91.44 meters]. Hemp crops must be isolated from other inseparable crops by a minimum of ten feet.

Specific field standards. a. Roguing to remove undesirable plants must be done before field inspection. Rogued plants must be removed from the field to be harvested. b. Any combination of impurities may be reason for failing an inspection. Unless otherwise specified by the breeder, an industrial hemp crop for certification must not exceed the limits specified in the following table. Impurities may include harmful contaminants (species capable of cross pollinating with the inspected variety), plants of other varieties or distinct types foreign to the variety being inspected, weeds, or other inseparable crops. c. The table indicates the maximum number of impurities permitted in approximately ten thousand plants of the inspected crop. Maximum Impurity Standards per Ten Thousand Plants in Hemp Seed Crops Maximum Number of Dioecious Male Plants Shedding Pollen Maximum Number of Off-Types or Other Varieties Dioecious type foundation - 3 Dioecious type registered - 10 Dioecious type certified - 20 Monoecious type foundation 1 3 Monoecious type registered 2 10 Monoecious type certified 100 20
