Interagency certification of crops and varieties other than those recommended by Cornell for use in New York and other than those listed in “Varieties Eligible for Certification” list, shall be considered only on prior application to the certifying agency. Approval for interagency certification of such a variety is contingent on it being recommended by an appropriate State agency in the area of intended use. Crop varieties not listed in “Varieties Eligible for Certification” but recommended by the Cornell University Agricultural Experiment Station for use by New York State farmers will be eligible for interagency certification upon application to the certifying agency.
