Colorado Revised Statutes Title 35. Agriculture § 35-26-101.5. Legislative declaration

(1) The general assembly hereby finds and determines that nursery stock can harbor plant pests and diseases and operate as a disease vector. Unregulated production and shipping of nursery stock presents an unacceptable risk to the state's agricultural, forestry, and horticultural interests and to the state's general environmental quality.

(2) Therefore, the general assembly hereby declares that it is necessary to ensure that nurseries produce healthy plants and that nursery stock shipped to other nurseries, brokers, or out-of-state customers meets the national nursery stock cleanliness standard.
