If both greenhouse or laboratory production and the field production are inspected by the official seed-certifying agency, then they will be considered separate production units. If only the greenhouse or laboratory production or only the field production is inspected, then it will be considered 1 unit. Storage, laboratory, greenhouse, and screenhouse inspection and testing protocols shall be approved by the director of the department of agriculture based on acceptable sanitation procedures.(d) Collect, or cause to be collected, representative tuber or plant samples of certifiable seed potatoes for winter testing or other tests as may be required for certification.(e) Issue certification tags, or bulk certificates for each container or bulk shipment of certifiable potatoes or, upon request by an applicant who has sold seed potatoes which must be shipped before the winter test results are known and which are otherwise certifiable, issue tags or bulk certificates for each container or bulk shipment that contains the statement that the potatoes met summer field and laboratory certification requirements but were shipped before the official winter test results were available.(f) Apply inspection tolerances to field inspections and winter tests on the basis of visual observations, except when deemed appropriate by the certifying agency to confirm visual observations or suspected latent infections by analytical methods.Mich.
