(1) Growing, transportation or processing of Brassica seed is regulated under provisions of this section only within the borders of a Brassica seed production district, as described in WAC 16-326-010.

(2) No Brassica seed crop grown for any purpose is regulated as part of a Brassica seed production district, if it is harvested or mowed before flowering or otherwise handled so that pollen production is prevented. Note that other regulatory requirements, such as the provisions of the crucifer seed quarantine rule found in WAC 16-301-490 through 16-301-580, are applicable.

(3) Brassica seed crops, including seed grown for planting and seed grown for crushing or extraction for fuel or oil, may only be grown in locations that have been identified in a timely manner through the pinning process.

(a) Pinning for Brassica seed production in Brassica seed production district 1 will be held at least once a year at the WSU Northwestern Washington Research and Extension Center, 16650 State Route 536, Mt. Vernon, Washington 98237. Contact the WSU Mount Vernon Skagit County Extension office at 360-428-4270 for information about pinning events for district 1.

(b) Pinning for Brassica seed production district 2 will be held at least once a year at the WSU Grant-Adams Area Extension office, 1525 E. Wheeler Road, Moses Lake, Washington 98837. Contact the WSU Grant-Adams Area Extension office at 509-754-2011, ext. 4313 for information about pinning events for district 2.

(c) Dates, times, locations and other information about pinning events will vary.

(d) Pinning for Brassica seed crops produced for planting must be performed by an authorized representative of the contractor for the crop. If the seed produced for planting is not being produced for a contractor, or if the contractor waives the pinning privilege, then the grower is responsible for pinning the location of the crop.

(e) Pinning for Brassica seed crops produced for fuel or oil must be performed by an authorized representative of the grower.

(4) Transportation and handling of Brassica seed within any Brassica seed production district must be performed in a way to prevent inadvertent spread of seed or production of volunteer plants. All shipments of viable seed must be in covered containers from which the seed cannot leak.

(5) Volunteer Brassica plants must be controlled as soon as feasible, but always prior to pollen production or blossoming.
