Land requirements for grass seed
certification. (1) Land requirements for production of grass
seed are as follows:
(a) A grass field planted with breeder seed for the
production of foundation seed must not have been seeded to the
same species, subspecies, variety, or strain of grass during the
preceding five years of planting. The field must be planted in
spaced rows. The five-year eligibility may be waived to three
years with the use of fumigants and other short-term soil
sterilization chemicals with prior approval of the certifying
agency.
(b) A grass field planted with foundation seed for the
production of registered seed must not have been seeded to the
same species, subspecies, variety, or strain of grass during the
preceding three years.
(c) A grass field planted with foundation, registered, or
certified seed for the production of certified seed must not have
been seeded to the same species, subspecies, variety or strain of
grass during the preceding year from planting unless the previous
planting was of the same variety and eligible to produce
foundation, registered or certified seed.
(d) Reseeding of a grass field because of failure or partial
failure of the first seeding may be done by referring to the
guidelines in WAC 16-302-045(5).
(e) Grasses of the same kind growing in fencerows and other
areas adjacent to the field must be controlled to prevent
blooming.
(f) Prohibited noxious weeds in the field, or on ditchbanks,
roadways, etc., adjacent to a certified field shall be controlled
to prevent seed formation.
