The general seed certification standards are basic and together
with the following specific standards constitute the standards
for the certification of small grains in Missouri.
Seed Source
The grower must have planted Foundation or Registered seed
of an eligible variety.

Isolation
- Since rye is a cross-pollinated plant, no other variety
may be located within 660 feet of the field(s) of rye being
produced under certification.
- Wheat, barley and oats must be separated from each other
or a different variety by a barren strip at least five feet
wide.

Land Requirements
Small grains may not be planted on land which
was in small grains the two previous seasons unless certified
seed of the same class and variety was grown.
Back to top
Field Standards
- Seed fields shall be inspected at least once prior to
harvest, preferably near maturity.
- It will be the responsibility of the applicant to rogue
and remove from each field any vetch and off-type plants.
- The field must be free of plants of onion, garlic, field
bindweed and relatively free of corn cockle and docks.
- Where two classes of the same variety (Registered and
Certified) are planted in the same field, you must show
on the application either the number of rows of each class
or have a marker at each end of the field showing where
one class ends and the other begins.
