Seed conditioning, sampling, and laboratory inspection
Cite as N.D. Admin. Code ยง 74-03-01-11
1.
Identification in storage. Field-inspected seed must be identified at all times. Identification
must be traceable to field inspection numbers from the crop year in which the seed was
produced. Conditioned seed in storage must be identified by kind, variety, class, and lot
number displayed on the bin or storage container.
2.
Preconditioned sample testing. To hasten labeling or determine the quality of seed which
has passed field inspection prior to conditioning, a representative sample of seed may be
submitted to the state seed department for the purpose of germination and disease testing.
The sample should be cleaned on a small mill or hand sieve to approximate as nearly as
possible the quality of the entire lot after conditioning.
Results of germination and disease tests conducted on preconditioned samples may be used
for final certification purposes. A labeler may request new tests for labeling purposes after the
seed lot is conditioned. Fragile crops such as soybeans, field beans, lentils, chickpeas, and
field peas must be tested for germination after the final conditioning of the seed lot to assure
correctness of label claims. The labeler is responsible in all cases for information stated on
seed labels.
3.
Conditioning. All field-inspected seed which is to be labeled must be conditioned and must
meet the minimum seed standards for the crop and class. Field-inspected seed may be
conditioned either by the grower or by an approved seed conditioner.
a.
Conditioning by seed grower.
(1)
A seed grower does not need an approved conditioning facility permit if the grower
conditions the grower's own seed on the grower's premises with the grower's
equipment.
(2)
The seed grower must complete a sampler's report in its entirety, attach the report
to a two-pound [.907-kilogram] sample that is representative of the entire seed lot,
and submit to the state seed department for analysis.
b.
Conditioning by an approved facility.
(1)
To be eligible for final certification, field-inspected seed shall be conditioned by a
facility approved by the seed department. Seed conditioned at an unapproved
facility will be ineligible for final certification.
(2)
If ownership of the seed lot is transferred to a different individual or entity, the
grower must complete and sign a grower's declaration. Transfer of ownership of
field-inspected seed is limited to an approved conditioner or bulk retailer unless the
transfer has been approved by the commissioner.
(3)
While conditioning, the seed lot must be sampled at regular intervals by an
authorized sampler. The sample and completed sampler's report must be submitted
to the state seed department for analysis.
4.
Sampling procedures. Representative samples of seed for testing and analysis must be
collected during or after conditioning in accordance with sampling procedures outlined in the
current association of official seed certifying agencies operational procedures. All seed lots
eligible for final certification shall be sampled during conditioning as follows:
a.
Portions of conditioned seed may be drawn by hand as seed is conditioned to form a
composite, representative sample for a seed lot; or
b.
Automatic mechanical devices may be used to continually or intermittently draw
representative samples as a seed lot is conditioned.
5.
Maximum lot size and numbering.
a.
The maximum lot size for bagged seed is five thousand bushels [17619.54 dekaliters]
except for small seeded legumes and grasses which is twenty-two thousand five hundred
pounds [10000 kilograms]. Bulk seed lots do not have a maximum size limit except bin
capacity. Each bin is considered a separate seed lot. For all crops, one sample for each
lot is required. The entire lot must be certified at the time final certification is completed.
b.
The lot number shall be designated by the labeler. For purposes of easier identification
on-site, the labeler should incorporate the storage bin number in the lot number.
6.
Commingling (mixing) of inspected seed fields. Seed of the same kind and variety from
different fields that pass field inspection may be commingled if the seed is of the same class
and general quality. If seed of different classes is commingled, the seed becomes eligible for
the lowest class only.
7.
The state seed department may resample any lot of seed before final certification or after the
seed is labeled.
8.
Official samples. At the request of a customer, an official sample may be collected by a
representative of the seed department, with expenses incurred by the customer. The seed
department shall determine the appropriate collection method and sample size. Sampling bulk
seed in bins requires that a minimal amount of seed is withdrawn from the bin. The amount
shall be determined by the quantity of seed in the lot, but shall be no less than five percent of
the total lot size. Test results from official samples shall supersede all previous test results and
shall be final.
9.
Laboratory analysis.
a.
All laboratory testing shall be done by qualified personnel of the state seed department.
Analysis and tests of seed samples and definition of analysis terms shall be in
accordance with the rules of the association of official seed analysts (AOSA). In certain
cases when time constraints are critical to the efficient movement of certified seed, the
commissioner may accept germination or other test results from an approved laboratory.
b.
If more than one sample of seed from the same lot is tested without additional
conditioning, an average shall be taken of all purity tests conducted. Results from the
most recent germination or disease test shall be used as the final result.
c.
Seed from certain classes or kinds, or both, may be subject to variety identification
analysis at the discretion of the department, with testing fees payable by the grower or
labeler.
