Section 285.623.209. Perennial cross-pollinated grasses (timothy, reed canarygrass, and orchardgrass).

(1) Timothy, reed canarygrass, and orchardgrass seed for the production of foundation seed shall be planted where the same species has not been seeded or grown for at least 5 years.

(2)    To be eligible for the production of timothy, reed canarygrass, and orchardgrass certified seed, a field shall not have grown or been seeded to the same species during the previous 2 calendar years unless either the crop was of the same variety and the same  or a higher seed class and passed field inspection for certification or had been summer fallowed for 2 full seasons before seeding  to  another  variety.  Fall  seeding  is permitted in the second year.

(3)   The certifying agency will determine the length of time that  fields will be eligible for certification.

(4)   Fields shall be rogued before harvest to remove off-type plants  and other grasses  or weeds  which  have seed  that cannot be removed by mechanical means.

(5)   Field standards for timothy, reed canarygrass, and orchardgrass seed are as follows:

Classes of Seed

Factor	Foundation	Certified
Other varieties 1	none	1:50
Isolation (feet)2	1,320	1653

1Maximum permitted ratio of plants.

2When different classes of seed of the same variety are being  grown  on the same or adjacent farms, the isolation requirements may be  reduced  to 25.0% of these distances. 3(a) For fields that are certifiable except   for   isolation,   the   field boundary may be established by placing permanent   5-foot    posts,  90  feet from the offending field, on either edge of the field.  The   crop  between the newly established boundary  lines  and the  offending   field  may  be removed after flowering as a separate field. The crop may be harvested  as uncertified seed.

(b) When 2 fields are separated by a natural or permanent barrier, such as a township, county, state, or federal highway, drainage ditch, or tree or shrub row, the isolation may consist of a 15-foot strip next to the barrier that can be either destroyed by mowing after bloom, but before harvest, or harvested as uncertified seed. The barrier shall be free of headed plants of the crop being inspected.

(6)   Seed standards for timothy seed are as follows:

(7)   Seed standards for reed canarygrass seed are as follows:
