[ Filed May 24, 2013, 10:49 a.m. , effective June 24, 2013 ]
Purpose: This rule-making order amends chapter 16-324 WAC, Rules for the certification of seed potatoes by:
(1) Adding an additional laboratory test for potato virus Y (PVY) for all lots entered for post-harvest testing;
(2) Eliminating the latent virus testing requirement for potato virus X (PVX);
(3) Adding definitions for "seed potato farm" and "ELISA testing";
(4) Allowing nuclear generation seed potatoes to be recertified if tests are negative for bacterial ring rot disease;
(5) Revising the requirement for physical separation in the field between lots of different classes (generations) or different varieties;
(6) Changing G1 requirement that the seed potatoes must be produced in a field that has not been planted with potatoes from three years to one year; and
(7) Requiring all G1 lots, with the exception of those lots of less than a quarter acre that are planted back on the same farm, to be post-harvest tested.

(1) A grower ((is)) may not ((eligible to produce nuclear, generation 1, or generation 2 seed potatoes)) 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.
(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. ((sependonicum)) sepedonicus (ring rot).
(a) Growers must leave a distinct separation ((of at least six feet unplanted or planted to some other crop)) between lots of seed potatoes from different classes. ((A similar)) 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:
