(ii) Hemp clones are to be handled in such a manner as to prevent co-mingling of varieties or types.
(iii) Facility is to have sufficient physical barriers between growth areas of hemp and other potential contaminating crops prior to flowering and inspection to prevent cross-contamination of type.
(b) Production requirements for open field production:
(i) Field eligibility - Crops should not be grown on land where remnant seed from a previous crop may germinate and produce volunteers that may cause contamination. Crops for mother plants must not be grown on land that produced another crop of hemp within the previous five years.
