Seed potato classification.

(1) All seed potatoes entered for certification are classified on the basis of production phases as follows:
(a) Prenuclear (PN) - Micropropagated potatoes or seed potatoes grown in a greenhouse or screenhouse under sanitary conditions free of insects, weeds that can harbor potato diseases or other sources of disease contamination.
(b) Nuclear (N) - First field production year.
(c) Generation 1 (G1) - Second field production year.
(d) Generation 2 (G2) - Third field production year.
(e) Generation 3 (G3) - Fourth field production year.
(f) Generation 4 (G4) - Fifth field production year.
(g) Generation 5 (G5) - Sixth field production year.
(2) If a seed lot fails to meet the standards established in this chapter for its class, then it will be reclassified to the earliest generation for which it meets established standards.

Production requirements.

(1) A grower may not recertify any seed lots, except nuclear, if ring rot has been detected on his or her seed potato farm during the previous two years. Nuclear seed potatoes may be recertified by the original grower if laboratory testing of the seed by a laboratory approved by the department shows negative results for ring rot.
(2) Prenuclear class.
(a) Prenuclear seed lots must be derived from disease tested micropropagated plants. All testing methods and laboratories must be approved by the department.
(b) A minimum of one percent (and not less than twenty samples) of prenuclear seed produced in a greenhouse must be tested and found free of potato virus X (PVX), potato virus Y (PVY), potato virus S (PVS), potato leafroll virus (PLRV), Erwinia carotovora ssp. caratovora (soft rot), Erwinia carotovora ssp. atroseptica (black leg), and Clavibacter michiganense ssp. sepedonicus (ring rot).
(c) The department will inspect all facilities used in the production of prenuclear class seed potatoes on a periodic basis. Department approval is necessary in order to utilize these facilities.
(3) Nuclear class.
(a) Nuclear class seed potatoes must be propagated entirely from prenuclear plants.
(b) Each nuclear class seed lot must be distinctly separated in storage and in the field.
(c) If a ground rig is used for spraying, wide enough spacing between rows must be left, so that tires will not touch plants during the growing season.
(d) Growers must plant cut seed and single drop seed separately, with single drop seed identified.
(4) Generations 1, 2, 3, 4 and 5.
(a) Growers must leave a distinct separation between lots of seed potatoes from different classes. The same separation must be left between different varieties, unless the varieties are readily distinguishable by visual observation. The separation must consist of one of the following:
(i) A strip of land at least six feet in width, that is unplanted or planted with another crop; or
(ii) Visible markers such as flags in every corner of the lot, and also at intervals not to exceed one hundred yards.
(b) When more than one lot of seed potatoes is planted in the same field, growers must stake or mark the identity of each lot.

(3) A postharvest test is required for seed lots that will be recertified, except when planted back on the same seed potato farm.
(4) In order to be eligible for certification in Washington state, seed lots from other states or countries must be eligible for recertification in the state or country of origin and must meet the requirements of this chapter.
(5) A seed lot blended from two or more different sources of seed is not eligible for recertification.
(6) A seed lot infected with powdery scab is not eligible for recertification.
(7) Generation 5 (G5) seed lots are not eligible for recertification.

Land requirements.

(1) The department will not accept any field infested with nematodes.
(2) Detection of ring rot in a field will make that field ineligible for production of certified seed potatoes for three years. Presence of volunteer potato plants in a field with ring rot history will disqualify the current field crop for certification. Plants outside of the defined row are considered volunteers.
(3) Nuclear class seed potatoes must be produced in a field that has not been planted with potatoes for at least four years.
(4) Generation 1, 2, 3, 4, and 5 class seed potatoes must be produced in a field that has not been planted with potatoes during the previous year unless the prior potato crop was certified seed potatoes of an earlier class of the same variety.

Field inspection.

(1) The department will visually inspect each seed lot at least two times during the growing season. The department may make additional inspections if the department deems it necessary.
(2) The department will reject all seed lots that do not comply with minimum field inspection standards at the time of inspection.
(3) Growers must notify the department of unusual field conditions, which may cause premature dying from any cause prior to the final reading of the field.
(4) Postharvest testing is required for any seed lot with a field condition preventing adequate field evaluation at the time of the first field inspection.
(5) If the department is unable to perform the final field inspection of a seed potato lot for any reason at least one of the following actions will be taken:
(a) The seed lot will be denied certification;
(b) The seed lot will be denied recertification; and/or
(c) The lot must be postharvest tested and found free of ring rot.
(6) The department will reject any seed lot in which ring rot is detected and will conduct additional inspections on all of the grower's remaining seed lots. The department will not recertify any seed lot associated with or planted after the rejected lot. The department will submit samples of ring rot detected during field inspections to an approved laboratory for confirmation.
(7) The department may require a postharvest test and withhold certification pending results of the postharvest test on seed potato lots exposed to any chemical that causes tuber-borne injury. Any seed potato lot showing five percent or greater tuber-borne chemical damage in the postharvest test will be rejected for certification.

(c) Lots for which a postharvest test is required by WAC 16-324-399.
(2) Testing of seed lots submitted for postharvest testing in subsection (1)(a) and (b) of this section by ELISA for PVY is optional. Seed lots officially sampled by the department for PVY testing will be subject to disease tolerance listed under WAC 16-324-420.
(3) A minimum of four hundred tubers must be submitted for each seed lot entered for postharvest testing. Seed lots less than 0.25 acre in size must submit a minimum of four tubers per total hundred weight with a minimum of fifty tubers.
(4) The applicant is responsible for the cost of postharvest testing.
(5) Seed lots in the postharvest test which fail to comply with the disease tolerance requirements set forth in WAC 16-324-420 are not eligible for recertification.
(a) The applicant must notify in writing all receivers of any seed lot that failed to comply with postharvest tolerances set forth in WAC 16-324-420.
(b) Acceptance of a seed lot that fails to comply with the tolerances set forth in WAC 16-324-420 must be based on a written buyer/seller agreement. The grower must provide the department with a copy of the written agreement within thirty days of receiving the postharvest results.
