I.
Amplification of General
Certification Standards.
A.
The General Standards are amplified as follows to apply specifically to
seeded type turf bermudagrass produced from vegetatively propagated fields. This
is done in accordance with the procedure specified by the originator.
B.
Only those fields planted from sprigs harvested from breeder or
Foundation fields will be eligible for certification. When fields are
established by vegetative propagation for reproduction, from different clones,
foundation plots of each clone must be maintained and inspected to insure
genetic purity (Standards for vegetative propagation will apply). This crop is
produced under a limited generation system as defined in section XLI A.
C.
For a field to be eligible for certification, the grower must notify the
Association in writing during the calendar year of planting or sprigging that he
intends to certify subsequent crops, although he need not certify the crop the
first year of any subsequent year.
II. Land Requirements
A.
A field to be eligible for the production of Foundation seed must not
have grown or been seeded to the same species during the previous five years and
must have included a cultivated crop for three years.
B.
A field to be eligible for the production of Certified seed must not have
grown or been seeded to the same species during the previous three years and
must have included a cultivated crop for two years unless the crop was the same
variety and passed field inspection for certification. All fields or portions of
fields intended for certification must have a definite boundary such as a fence,
ditch, roadway or barren strip at least ten feet wide.
C.
A field to be eligible for the production of Foundation or Certified
planting stock must have been thoroughly inspected at a time prior to planting
(pre-plant inspection), when objectionable plants can be determined, and must
have been found to be free of (or
controlled/contained) noxious weeds and other strains of the same species being
planted. Further the field being inspected must not have been tilled or
otherwise molested prior to the inspection in such a way as to obscure
objectionable weeds.
III.
Field Inspection
A.
Each field intended for certification must be inspected prior to planting
and at harvest; one additional inspection shall be made after greenup and prior
to heading depending on the type being inspected. A fall inspection may be
applicable if needed.
IV.
Field Standards
A. General
1.
Unit of certification
The unit of certification
shall be a field, but a portion of a field may be approved provided the
discarded portion can be harvested separately and is eliminated from
certification.
2.
Isolation
A field to be eligible for certification
must be isolated from any other perennial grass, meeting isolation standards, by
a barrier that will prevent encroachment or mechanical mixing during harvest.

in the above table.
3.
Sod Production
If the turf type seeded variety
production field is established from clonal stock it may not be used for any
class of certified sod production. Only Foundation seed may be used to produce
Certified sod.
