GRASS SEED
CERTIFICATION REQUIREMENTS AND
STANDARDS
I. BASIC RULES
The UCIA General Seed
Certification Requirements and Standards are basic and with the following
constitute the requirements and standards for grass seed certification.
II. SEED PRODUCTION
A. APPLICATIONS
1. Dates
and fees for applications are as listed in the General Requirements and
Standards.
2.
For the seedling year, fill out "Application for Certification
for Annual Crops and Seedling Perennial Crops"; in the second and subsequent
years fill out "Application for Certification for Established Perennial
Crops".
B. SEED
ELIGIBILITY
A list of grass varieties currently
certified in Utah (See Prefix A) is updated periodically, but other varieties
may be eligible. Note the seed
classes eligible to plant for certification; in some varieties there is no
Registered class.
C. LAND
REQUIREMENTS
1. Grass
entered for certified seed production must be planted on land free from any
type of perennial grass plants (including quackgrass and other weedy perennial
grasses) as determined by field inspection by a UCIA representative at a time
preceding planting when such grasses would be actively growing.
2. Foundation,
Registered, and Certified seed must be produced on land which has not grown or
been seeded to the same genus during four, three, or two years, respectively,
prior to the year of proposed planting.
3. Isolation:
a. A
fenceline, roadway, or strip at least 5 feet in width and which is mowed,
uncropped, or planted to some other crop than the kind in question shall
constitute a field boundary (unit of certification).
b. A
seed field, to be eligible for the production of a class of certified seed,
must be isolated from any other strain of the same species or any other species
with which cross pollination occurs, in bloom at the same time, as listed
below:

*a The isolation distances also apply to the following wheatgrass
selections which cross in varying degrees under field conditions:
Intermediate wheatgrass (Agropyron
intermedium = Thinopyrum intermedium) must be isolated from pubescent wheatgrass (Agropyron
trichophorum = Thinopyrum intermedium).
"Standard" crested wheatgrass
(Agropyron desertorum), Siberian wheatgrass (Agropyron fragile = sibiricum) and 'Fairway' crested wheatgrass
(Agropyron crisatum; often contaminated with A. desertorum
types) must be
isolated from each other and from hybrids such as 'Hycrest' and 'CD II'.
Beardless wheatgrass (Agropyron
inerme = Pseudoroegaeria spicata), bluebunch wheatgrass (Agropyron spicatum = Pseudoroegaeria spicata), and R/S Hybrid wheatgrass
(bluebunch wheatgrass X quackgrass) must all be isolated from each other; R/S
Hybrid wheatgrass must also be isolated from quackgrass (Agropyron repens).
Streambank wheatgrass (Agropyron
riparium = Elymus lanceolatus) must be isolated from thickspike wheatgrass (Agropyron
dasystachyum = Elymus
lanceolatus).
Snake River wheatgrass is a subspecies
of Elymus lanceolatus and the variety 'Secar' must be isolated from both bluebunch (beardless) wheatgrass
and streambank (thickspike wheatgrass) selections.
*b When
different classes of the same variety are being grown on the same or adjacent
fields, the isolation requirements may be reduced to 25% of that shown in the
above table.
*c Isolation
distance may be reduced by removing specified border on fields of 5 acres or
more. Such removal shall not occur
until pollination of the crop to be certified is completed.
*d Isolation
for the Certified class is based on the size of the certified field and the
percentage of the field within 165 feet of another variety of grass. If 10 percent or less of the certified
field is within the 165 foot isolation zone, no isolation is required--only a
definite separation such as a road, fenceline, bare ground, etc. If more than 10 percent of the field is
within the isolation zone, that part of the field must not be harvested as
certified seed.
The "isolation zone" is
that area calculated by multiplying the length of the common border(s) with
other varieties of grass by the average width of the certified grass field
falling within the 165 ft. isolation distance requirement.
D. SEEDING
1. It
is recommended that grasses be planted in rows at least 18 inches (preferably
30" - 36") apart so that (a) volunteer plants and weeds may be
cultivated out; (b) makes it
easier to inspect and rogue out off-types; and (c) seed yields will be maximized.
2. When
more than one strain or variety of any one genus of grass may be grown for seed
production on any one farm the UCIA must be consulted to ensure proper planting
equipment cleanup and field isolation so varietal mixtures do not occur.
3. Reseeding
new grass plantings shall be limited to the first two years, and the field must
be inspected before reseeding.
Additional fees may be charged for re-inspection. The seed source for reseeding must be
of the same class as the original seed used, or the field will be reclassified
to the lowest seed class planted.
E. FIELD
INSPECTION
1. A
seedling inspection will be made by a UCIA representative during the first
season of growth to evaluate the stand and perennial weed control status.
2. At
least one field inspection after heading out but before harvest will be made
each year that a certified seed crop is to be harvested.
F. FIELD
STANDARDS
1. Fields
producing Foundation or Registered seed will be subject to reclassification or
rejection if volunteer plants of the same species are allowed to mature
seed. Excessive natural reseeding
may disquality Certified fields.

G. HARVEST
Grass seed may be moved in bulk (box
or truck) or in bags (each clearly identified) from the harvesting machine to
farm storage or to conditioning facilities. Identity and purity of seed must be maintained and prior
approval of equipment and facilities used for transporting, handling, and
storing of seed must be given by a UCIA representative.
