Current through Register Vol. XLI, No. 28, July 12, 2024
42.1. Isolation
				areas shall be kept free of any harmful plants that can cause contamination.
				The area, density, stage of maturity, and location of any contaminating pollen
				source is an important factor in cross pollination, and therefore shall be
				noted on the
Seed Crop Inspection Report
for consideration in
				determining certification status. There shall not be any
Cannabis
				sativa
L. plants within 100 m of the crop and not more than 10
				plants/ha beyond 100 m within the isolation requirement. The conditions of each
				crop are assessed by the department, which may alter this standard, usually by
				reducing the number of contaminant plants permitted per square yard, according
				to identified contamination risks.
42.2. The required isolation shall be present
				prior to flowering and crop inspection.
42.3. Industrial hemp seed production crops
				for certification shall be isolated from all other industrial hemp varieties or
				fields not meeting the varietal purity requirements for certification as
