THE SAMPLING OF SEED LOTS.
10.1.
General Procedure:
(a)
In order to secure a representative sample, equal portions shall be taken from evenly
distributed parts of the quantity of seed to be sampled. Access shall be had to all parts of
that quantity.
(b)
For free-flowing seed in bags or bulk, a probe or trier, shall be used. For small free-
flowing seed in bags a probe or trier long enough to sample all portions of the bag shall
be used.
(c)
Nonfree-flowing seeds, such as certain grass seed, uncleaned seed, or screenings,
difficult to sample with a probe or trier, shall be sampled by thrusting the hand into the
bulk and withdrawing representative portions.
flowing seed in bags or bulk, a probe or trier, shall be used. For small free-
flowing seed in bags a probe or trier long enough to sample all portions of the bag shall
be used.
(c)
Nonfree-flowing seeds, such as certain grass seed, uncleaned seed, or screenings,
difficult to sample with a probe or trier, shall be sampled by thrusting the hand into the
bulk and withdrawing representative portions.
(d)
Composite samples shall be obtained to determine the quality of a lot of seed, such as
the percentages of pure seed, other crop seed, weed seed, inert matter, noxious weed
seed, germination, varietal purity, freedom from disease, and effectiveness of seed
treatment. Individual bag samples may be obtained to determine whether the seed is of
uniform quality.

CODE OF COLORADO REGULATIONS

10.2.
Sampling Equipment:
For sampling seeds in bags a trier long enough to reach all areas in the bag shall be used. The trier shall
be so designed that it will remove an equal volume of seed from each part of the bag through which the
trier travels. Unless the trier has partitions in the seed chamber it must be inserted into the bags

The following rules are hereby promulgated under the authority of the Colorado Seed Act pursuant to 35-
27-101 through 125, C.R.S., (1993 Supp. as amended by Senate Bill 93-17). These rules are required by
the Colorado Seed Act, which was repealed and reenacted by the 1993 State Legislature.
They deal with definitions of certain terms used which are not defined in the Act; the requirements for
registration of seed labelers, custom seed conditioners, and retail seed dealers, including the setting of
registration fees; label requirements for agricultural, vegetable and flower seeds, including seed mixtures
and combination mulch, seed and fertilizer products, performance characteristics of flower seed, and
germination standards for flower seeds and for vegetable seeds; label requirements for tree and shrub
seeds; the lists of prohibited and restricted noxious weed seeds; seed sampling requirements and
procedures; analysis and testing of seeds; tolerances on seed label information; and requirements
concerning sales of disease free seed beans.
These rules repeal 8 CCR 1203-6, Parts I through VIII (sic IX) (April 1993), and new rules are adopted in

Adopted October 2, 2003 - Effective December 1, 2003
(a)
Statutory Authority: These amendments to the permanent rules pertain to the registration fees of
the Colorado Seed Act, § § 35-27-101 through 125, C.R.S. (2002), and are adopted by the
Commissioner of Agriculture pursuant to § § 35-27-111(4)(a)(I) and 114(1)(b)(VIII), C.R.S.
(b)
Purpose: The purpose of these amendments are to increase the registration fee to allow more
funds to be spent on seed sample analysis to verify that seed labeling is in compliance with the
Colorado Seed Act and these rules.
(c)
Factual and Policy Issues: The factual and policy issues encountered in the proposal of these
permanent rules are as follows:
(1)
Seed sampling and analysis to determine truth in labeling is an essential consumer and
environmental protection function of the seed regulatory program conducted under the
Colorado Seed Act. Samples are analyzed to ensure that the labeling components such
as pure seed and germination percentage are accurate to protect the consumer. In
addition, the analysis can detect any weed seed present in the product to protect both the
consumer and the environment. The Colorado Department of Agriculture (CDA) performs
the seed sampling and the Colorado State University Seed Laboratory (CSU Laboratory)
provides the analysis function through a contract with CDA. CDA does not have qualified
staff to conduct seed analysis.

(2)
Use of the CSU Laboratory provides an objective third party analysis when regulatory
action is required because of seed analysis results. It prevents potential conflict of
interest concerns that a private laboratory would encounter particularly since companies
regulated under the Colorado Seed Act operate many of the private seed laboratories. In
addition, it saves CDA costs by not having to develop and conduct a system to provide all
of the samples as “blind samples” to a private laboratory to ensure they cannot determine
the place the sample was taken from. Other regulatory seed laboratories operated by
Departments of Agriculture or Universities in other states have no interest in performing
seed analysis for Colorado.
(3)
The CSU Laboratory revenues have decreased in recent years. This decrease has
caused the laboratory to reduce staff to a level that is not sustainable for operation in the
long term. To obtain sufficient revenue the Laboratory must raise seed analysis costs to
its customers such as the Colorado Department of Agriculture.
(4)
The Colorado seed industry believes the CSU Laboratory provides an essential function
for processing regulatory samples as well as in the education of seed analysts.

be analyzed with the results of a tetrazolium test.
10)
To adopt a new Rule 11.2 which states that the time that a germination test is valid is 13 months,
unless it is stored in hermetically sealed containers, in which case it shall be valid for 24 months.
11)
To adopt a new Rule 11.3 specifying what kinds of cool season grasses will be allowed to be
labeled as to germination for a period of 16 months instead of the standard 13 months, as
allowed under in §35-27-113(1)(a) , C.R.S.
12)
To adopt a new Rule 11.4 which establishes the length of time during which a tetrazolium test is
valid for labeling purposes.
13)
To amend existing Rule 12 to update the tolerance and methods of determination used in the
enforcement of these rules to incorporate the most current tolerances and methods in the
Association of Official Seed Analysts Rules for Testing Seeds, 2008 edition.

and replace them with the correct reference.
16)
To amend Rule 14 to delete outdated references to Section Chief and Plant and Insect Section
and to replace them with the term “Seed Program Coordinator”.
17)
To amend existing language in several places to correct typographical errors.
Factual and Policy Basis Issues
The factual and policy issues encountered when developing these rules include:
1)
The proposed new Rule 1.2(j) is necessary because the term, “tetrazolium test”, which is used in
§35-27-113(1)(a), C.R.S., is not defined in the Act.
2)
A tetrazolium test is different from a germination test in that a tetrazolim test only determines the
percentage of the seeds that are viable (living) rather than the percentage of the seeds that will
likely germinate. Prior to the amendment to §35-27-113(1)(a), C.R.S., in 2007, and the
implementation in these rule changes, seed could not have been labeled with a tetrazolium test.
Because the use of a tetrazolium test will now be allowed for specifically identified seeds; the test
is less stringent; and consumers are used to the label data being obtained from a germination
test; it is necessary to inform them of this fact so they can make an informed purchasing decision.
3)
The amended language to Rules 7.1 and 7.2 is necessary because they contain effective dates
for certain noxious weeds that are now obsolete and confusing.
4)
The amended language to 8.2 is necessary to clarify that the figures are stated as percentages in
the table below the header sentence.

make an informed purchasing decision.
3)
The amended language to Rules 7.1 and 7.2 is necessary because they contain effective dates
for certain noxious weeds that are now obsolete and confusing.
4)
The amended language to 8.2 is necessary to clarify that the figures are stated as percentages in
the table below the header sentence.

CODE OF COLORADO REGULATIONS

26
5)
The amended language to Rule 8.1 is necessary to update the rule to bring it in conformity with
the current list of the kinds of vegetable seeds listed and their germination standards in the
Association of Official Seed Analysts Rules for Testing Seeds, 2008 edition.
6)
The new Rule 8.2 is necessary to specify that all vegetable and herb seeds not listed shall have a
designated germination standard since they presently do not. This change is necessary also to
bring these rules into conformity with the Recommended Uniform State Seed Law (RUSSL), as
adopted by the Association of American Seed Control Officials, July 2007 edition, for germination
standards for vegetable and herb seeds not listed.
7)
The proposed new Rule 9.3 is necessary because it will better facilitate inspection and/or
sampling of all seed.
8)
The amended language to Rule 11 is necessary because the old references are obsolete.
9)
New Rules 11.1(a) and 11.1(b) are necessary because the Commissioner is required to specify
by rule which seeds may be analyzed by means of a tetrazolium test. Rule 11.1(a) will allow
certain kinds of seeds that presently do not have established germination standards written for
them by the Association of Official Seed Analysts Rules for Testing Seeds, 2008 edition, to be
analyzed with a tetrazolium test in place of a germination test
ssary because the Commissioner is required to specify
by rule which seeds may be analyzed by means of a tetrazolium test. Rule 11.1(a) will allow
certain kinds of seeds that presently do not have established germination standards written for
them by the Association of Official Seed Analysts Rules for Testing Seeds, 2008 edition, to be
analyzed with a tetrazolium test in place of a germination test. Rule 11.1(b) will allow analysis
with a tetrazolium test these three kinds of seeds, Indian ricegrass (Achnatherum hymenoides),
fourwing saltbush (Atriplex canescens), and chokecherry (Prunus virginiana), that presently do
have rules written for them by the Association of Official Seed Analysts Rules for Testing Seeds,
2008 edition, but do not germinate in a timely fashion.
10)
The proposed new Rule 11.2 is necessary to clarify the valid time for germination tests.
11)
The proposed new rule 11.3 is necessary due to the new language added to §35-27-113(1)(a),
C.R.S. in 2007, which allows specified cool season grasses to be labeled for germination for a
period of 16 months instead of the 13 months specified for all other non-hermetically sealed
containers. These cool season grasses have been shown to retain the germination for a period
longer than 13 months in most cases (i.e. not exposed to direct sunlight, excessive moisture or
high temperatures).
12)
The proposed new Rule 11.4 is necessary because implementation of the tetrazolium test as a
replacement for the germination test for certain kinds of seed requires the establishment of a time
period of validity for labeling purposes. Furthermore, it is scientifically valid and more manageable
to the industry and consumers to stay with the time frame for the validity of the germination test,
for labeling purposes, for these same kinds of seed.
13)
The amended language to Rule 12 is necessary because the old tolerances and methods
referenced are obsolete
uires the establishment of a time
period of validity for labeling purposes. Furthermore, it is scientifically valid and more manageable
to the industry and consumers to stay with the time frame for the validity of the germination test,
for labeling purposes, for these same kinds of seed.
13)
The amended language to Rule 12 is necessary because the old tolerances and methods
referenced are obsolete.
14)
The proposed new title to Part 13 is necessary to bring clarity and continuity to the seed
regulations as the title to Part 13 was removed accidentally when the Rules were converted to the
electronic format.
15)
The amended language to Rule 14 is necessary because the old references are obsolete.
16)
The amended language in Rule 14 is necessary because the old references are obsolete. The
Plant and Insect Section was eliminated as an identified entity within the Division of Plant
Industry.
17)
The amended language is necessary to eliminate typographical errors that had been incorporated
into prior versions of this Act.

20.6
Adopted November 19, 2009 - Effective December 30, 2009
Statutory Authority
These amendments to these rules are proposed for adoption by the Commissioner of the Colorado
Department of Agriculture (“CDA” ) pursuant to his authority under the Colorado Seed Act (the “Act”), §
35-27-114(1)(b), C.R.S.
Purpose
The purpose of this proposed rule amendment is to increase the registration fee paid by retail seed
dealers from $25 per year to $50 per year.
Factual and Policy Basis Issues
The factual and policy issues encountered when developing these rules include:
1)
By statute the Seed Program is funded by a combination of general funds and cash funds. The
revenue for the cash funded portion is generated by the registration fees paid by seed registrants
to label, condition or sell seed in Colorado
il seed
dealers from $25 per year to $50 per year.
Factual and Policy Basis Issues
The factual and policy issues encountered when developing these rules include:
1)
By statute the Seed Program is funded by a combination of general funds and cash funds. The
revenue for the cash funded portion is generated by the registration fees paid by seed registrants
to label, condition or sell seed in Colorado.
2)
Pursuant to 35-27-111 Registration of Seed Conditioners, Farmer Seed Labelers, Retail Seed
Dealers, and Seed Labelers – Forms –Fees-Renewals; there are four types of seed registrations
in the Seed Act and Rules and Regulations. These four types are Seed Conditioners, Farmer
Seed Labelers, Retail Seed Dealers, and Seed Labelers. The Seed Conditioners maximum fee
allowed by statute is $300. The current fee is $300. The Farmer Seed Labelers maximum fee
allowed by statute is $75. The current fee is $75. The Retail Seed Dealers maximum fee allowed
by statute is $75. The current fee is $25. The Seed labelers maximum fee allowed by statute is
$300. The current fee is $300.
3)
During the 2008 legislative session the General Assembly removed $20,000 from the general
funded portion of the seed program budget to help with the overall State budget needs.
4)
The seed program has consistently cut back on the work conducted by the program to meet
budget constraints. This is documented in the number of seed samples collected and seed
inspections performed. The program took 550 seed samples in 1999 and has gradually reduced
that number to the current 301 to account for budget constraints. The program averaged over 900
seed inspection per year in the late 1990s and is now conducting about 650 inspections per year.
5)
In order to avoid reducing the program activities more and therefore decreasing the value of the
program, the industry seed ad hoc advisory committee recommended that fees be increased to
offset the general fund revenue removed in 2008
to account for budget constraints. The program averaged over 900
seed inspection per year in the late 1990s and is now conducting about 650 inspections per year.
5)
In order to avoid reducing the program activities more and therefore decreasing the value of the
program, the industry seed ad hoc advisory committee recommended that fees be increased to
offset the general fund revenue removed in 2008.
6)
Since the only fee not at the statutory cap is the Retail Seed Dealer registration it is proposed to
raise this fee.
7)
The program has an average of 900 retail seed registrations per year. 900 registrations multiplied
by the $25 increase would generate roughly $22,500.
8)
The fees for this category of seed registration have not been increased since the statutory
change to have seed registrations and fees was enacted in 1993.

Adopted June 12, 2019 – Effective July 30, 2019
Statutory Authority
These amendments to these rules are proposed for adoption by the Commissioner of the Colorado
Department of Agriculture (“CDA”) pursuant to the authority under the Colorado Seed Act (the “Act”), §
35-27-114(1)(b), C.R.S.
Purpose
The purpose of this proposed rule amendment is to:
1.
Increase the registration fee paid by retail seed dealers from $50 to $75 per year.
2.
Increase the additional location fee paid by seed dealers and seed conditioners from $25 to $75
per year.
3.
Update the reference to the Tetrazolium Test to the 2010 edition, published by the Society of
Commercial Seed Technologists and the Association of Official Seed Analysts.
4.
Update the reference used to measure tolerance of seed testing when enforcing truth in labeling
to the October 2018 edition of the Rules for Testing Seeds, published by the Association of
Official Seed Analysts.
5.
Update the department address to its current location in Broomfield, CO.
Factual and Policy Basis Issues
The factual and policy issues encountered when developing these rules include:
1
Update the reference used to measure tolerance of seed testing when enforcing truth in labeling
to the October 2018 edition of the Rules for Testing Seeds, published by the Association of
Official Seed Analysts.
5.
Update the department address to its current location in Broomfield, CO.
Factual and Policy Basis Issues
The factual and policy issues encountered when developing these rules include:
1.
By statute, the Seed Program is funded by a combination of general funds and cash funds. The
revenue for the cash funded portion is generated by the registration fees paid by seed registrants
to label, condition, or sell seed in Colorado. The current registration fees do not provide sufficient
revenue to administer the Seed Program effectively, and, without increasing the fees, the
Department would need to cut back on work conducted by the Seed Program (i.e., seed
collection, sampling, and testing). To Date, the Department has curtailed its sampling from 550
seed samples in 1999 to 250 seed samples at present and over 900 seed inspections per year in
the late 1990s to approximately 300 inspections per year at present.
2.
Pursuant to section 35-27-111, C.R.S., there are four types of seed registrations: seed
conditioners, farmer seed labelers, retail seed dealers, and seed labelers. The only fees not
presently at the statutory cap are the retail seed dealer registration fee and additional location
fees for seed labelers and seed conditioners. therefore, these are the only categories in which the
Department may increase fees.
3.
The Industry Seed Ad Hoc Advisory Committee recommended that fees be increased to address
the funding deficit and to ensure that program activities not be negatively affected.
4.
The Seed Program has an average of 900 retail seed dealer registrations per year (355 primary
locations + 563 additional locations). 355 registrations multiplied by the $25 increase would
generate roughly $8,875 for the Seed Program.

The Seed Program has an average of 900 retail seed dealer registrations per year (355 primary

5.
The Seed Program has an average of 300 registered seed labelers and seed conditioners, with
approximately 50 of those 300 registrations including additional locations. Increasing the
additional location fee for these businesses would raise $2,500 for the Seed Program.

The amendments to these rules are proposed for adoption by the Commissioner of the Colorado
Department of Agriculture (“CDA”) pursuant to the authority under the Colorado Seed Act (the “Act”), §
35-27-114(1)(b), C.R.S.
Purpose
The purpose of the proposed rule amendments is to:
1.
Update incorporation by reference language for the Tetrazolium Testing Handbook (“Handbook”)
and the Rules for Testing Seed (“Testing Rules”), published by the Society of Commercial Seed
Technologists and/or the Association of Official Seed Analysts, to meet the requirements of § 24-
4-103(12.5)(a)(iv), C.R.S, of the State Administrative Procedure Act.
Factual and Policy Basis Issues
The factual and policy issues encountered when developing these rules include:
1
ing Handbook (“Handbook”)
and the Rules for Testing Seed (“Testing Rules”), published by the Society of Commercial Seed
Technologists and/or the Association of Official Seed Analysts, to meet the requirements of § 24-
4-103(12.5)(a)(iv), C.R.S, of the State Administrative Procedure Act.
Factual and Policy Basis Issues
The factual and policy issues encountered when developing these rules include:
1.
The State Administrative Procedure Act sets forth the requirements for incorporating by reference
all or any part of a code, standard, guideline, or rule that has been adopted by an agency of the
United States, this state, or another state, or adopted or published by a nationally recognized
organization or association.
2.
Specifically, the State Administrative Procedure Act requires that the rule states where copies of
the code, standard, guideline, or rule are available for a reasonable charge from the agency
adopting the rule and where copies are available from the agency of the United States, this state,
another state, or the organization or association originally issuing the code, standard, guideline,
or rule.
3.
Although the rules identified the publishers of the Handbook and the Testing Rules by name, they
did not provide an address or website where the Handbook or Testing Rules could be obtained
from the publishers. The amendments to the rules now include a specific URL where the
Handbook and Testing Rules can be obtained for purchase from the publishers.
4.
A newer version of the Testing Rules became effective October 1, 2019, and the rule
amendments update the relevant edition to 2019.

Factual and Policy Basis Issues
The factual and policy issues encountered when developing these rule amendments include:
1.
Section 35-27-125, et seq., C.R.S., was set for repeal on July 1, 2020. Prior to repeal, the Act
was scheduled to undergo a sunset review through the Department of Regulatory Agencies
(“DORA”), consistent with section 24-34-104, C.R.S. Subsequent to the sunset review, DORA
recommended continuation of the Act

was scheduled to undergo a sunset review through the Department of Regulatory Agencies
(“DORA”), consistent with section 24-34-104, C.R.S. Subsequent to the sunset review, DORA
recommended continuation of the Act. The General Assembly reviewed DORA’s
recommendations and passed House Bill 20-1184. House Bill 20-1184 continued the Act, and
codified into the statute minimum yearly registration fees for each registration category and for
certain categories of second business locations.
2.
Because the fee provisions in the Act became effective June 25, 2020, the fees described in the
Rules were no longer accurate. As such, the Department is revising the Rules to harmonize the
Rules to the Act. This will avoid stakeholder confusion with respect to operative fees moving
forward.
