Planting seed in the western Washington regulated area—Protocols when certain documentation is unavailable.
When no documentation exists verifying that a crucifer seed lot is free from regulated diseases, the following protocols must be followed before the seed is planted in the western Washington regulated area:
(1) A crucifer seed lot will be classified as a suspect seed lot if the seed lot lacks the documentation verifying that the lot complies with the crucifer seed quarantine requirements of this chapter.
(2) Suspect seed lots must:
(a) Not be offered for sale in the western Washington regulated area.
(b) Be treated by an approved treatment method.
(c) Be sown in a greenhouse and the seedlings must pass inspection by seed program inspectors before transplanting to the field.
(3) Any greenhouse operation used to grow crucifer seedlings for transplant must:
(a) Physically separate suspect seed lots from other crucifer production within that greenhouse.
(b) Monitor and document the location and identity of each suspect seed lot during production.
(4) It is a violation of this chapter for seedlings from a suspect seed lot to be topped, clipped, chopped or undergo any other treatment to toughen them or reduce their size.
(5) All seedlings from a suspect seed lot that exhibit symptoms of regulated diseases must be physically separated from asymptomatic transplants in that lot.
(6) Before shipping seedlings from a suspect seed lot, the seedlings must be inspected by department seed program inspectors for the presence of regulated diseases.
(a) If no symptoms of regulated diseases are detected during this inspection, the suspect seed lot is considered in compliance with this chapter and may be sold and planted within the western Washington regulated area.
(b) If seedlings display symptoms of regulated diseases, laboratory testing for the diseases is mandatory.
(c) If seedlings from a suspect seed lot test negative for regulated pathogens or diseases after appropriate pathological testing, the suspect seed lot is considered in compliance with this chapter and may be sold and planted within the western Washington regulated area.
(d) If the presence of a regulated disease is confirmed by laboratory testing, all seedlings from a suspect seed lot may be subject to a quarantine order or destruction order under WAC 16-301-570.
(7) Any crucifer seed production fields, plant beds, or greenhouse production that will be planted with or receives production from suspect seed lots that are determined to be free from regulated diseases under subsection (6) of this section must be entered into the Washington state phytosanitary inspection program as required under WAC 16-301-240.
(8)(a) It is a violation of this chapter to plant seedlings from a suspect seed lot that tests positive for any regulated disease in the western Washington regulated area.
(b) Any suspect seed lot testing positive for any regulated disease may be subject to a quarantine order or a destruction order under WAC 16-301-570.
