Seed classes recognized for seed certification.

For the eligibility of varieties of seed refer to WAC 16-302-040. Four seed classes are recognized in seed certification, namely: Breeder, foundation, registered, and certified.
(1) Breeder seed is seed or vegetative propagating material directly controlled by the originating, or in certain cases the sponsoring plant breeder, institution, or firm. Breeder seed supplies the source for the initial and recurring increase of foundation seed. Breeder seed may also be used to produce subsequent generations.
(2) Foundation seed (identified by white tags) is first-generation seed increased from breeder seed or its equivalent. Production must be carefully supervised and approved by the certifying agency and/or the agricultural experiment station. Foundation seed is eligible to produce registered or certified seed.
(3) Registered seed (identified by purple tags) is the progeny of breeder or foundation seed that is handled as to maintain satisfactory genetic identity and purity and is approved and certified by the certifying agency. Registered seed is eligible to produce certified seed.
(4) Certified seed (identified by blue tags) is the progeny of breeder, foundation, registered or certified seed which is handled as to maintain satisfactory genetic identity and purity and is approved and certified by the certifying agency. Certified seed is not eligible for recertification, except as provided for in WAC 16-302-035.
[Statutory Authority: RCW 15.49.005, 15.49.081, 15.49.310, 15.49.370(3), and chapter 34.05 RCW. WSR 14-20-050, § 16-302-015, filed 9/25/14, effective 10/26/14.

16-302-020
Seed standards for proprietary variety certification—Application for proprietary certification.

The general seed certification standards provided for in this chapter together with the varieties eligible for seed certification constitutes the basic requirements for proprietary variety certification.
(1) The owner or designee with production or marketing rights of a proprietary variety must submit to the certifying agency a list of growers who will submit applications for certification showing the variety, acreage authorized, processor authorized, and also advising whether the variety is under genetic purity certification or under complete certification. The list of growers must be submitted prior to the application due dates for seed certification as specified in WAC 16-302-050.
(2) Each application for seed certification received by the certifying agency is subject to approval from the list submitted by the owner with production or marketing rights of a proprietary variety.
(3) The certifying agency shall refuse certification of any seed that appears in a processing or conditioning plant not authorized by the owner with production or marketing rights of a proprietary variety.
(4) An application for seed certification may be withdrawn at any time prior to tagging. The applicant is responsible for fees due and owing when an application for seed certification is withdrawn.
[Statutory Authority: RCW 15.49.005, 15.49.081, 15.49.310, 15.49.370(3) and chapter 17.24 RCW. WSR 00-24-077, § 16-302-020, filed 12/4/00, effective 1/4/01.]



16-302-025
Seed standards for genetic purity certification.

All certified seed must conform to the standards of purity and identity or variety in compliance with chapter 15.49 RCW and rules adopted thereunder. The general certification standards together with the specific crop certification standards established in this chapter are the basic requirements for genetic purity seed certification:
(1) Only proprietary varieties and OECD varieties not of United States origin to be tagged under the OECD scheme are eligible for genetic purity certification.
(2) Only the specific crop certification standards established in rule which pertain to genetic purity such as land requirements and isolation, shall apply for genetic purity certification. Fields must not contain other varieties or off-type plants in excess of established standards. The grower is responsible for controlling noxious weeds to prevent seed formation.
(3) Excessive prohibited and/or objectionable weeds, poor stands, lack of vigor, or other conditions, which make inspection by the certifying agency inaccurate, may be cause for rejection of a field.
(4) Field inspection. A field inspection is made by the certifying agency each year at the time the seed crop is in bloom, or at other times as may be most advantageous to determine genetic purity. A complete record must be maintained on the condition of the field (weeds, crop mixtures, etc.) and all information reported to the authorized agent and/or grower. Upon completion of all requirements for field inspection, a final field inspection report is issued by the certifying agency that the seed produced passed genetic purity requirements.
(5) Seed standards. The certifying agency shall test all lots to determine the purity and germination quality. Seed to be certified must not contain seeds of other varieties or off-types in excess of standards established in rule. The quality of each lot of seed represented to be certified must be that which is normally acceptable in the marketing of high quality seed. Failure to maintain acceptable quality shall be considered cause for revoking permission to participate in seed certification by genetic purity.
(6) Processing or conditioning requirements. Only those conditioning plants approved by the department Seed Program are permitted to process seed for certification. Complete records must be kept of all processing or conditioning. Blending of seed lots of the same variety from fields passing field inspections may be permitted with prior approval and if in accordance with requirements for blending. Sampling and all other operations involving certified seed must be under supervision of the certifying agency. The sample must be obtained in accordance with official sampling procedures. The entire lot must be cleaned and in condition for sale at the time of sampling. This sample must be submitted to the seed laboratory for testing to evaluate quality. Lots of questionable quality may be rejected and not eligible for certification.
(7) Certification tags for seed meeting the genetic purity standards must be clearly marked, "genetic purity certified."
(8) Fees for genetic purity certification are as established for each seed crop in chapter 16-303 WAC and the authorized agent or grower is responsible for all fees.
[Statutory Authority: RCW 15.49.005, 15.49.081, 15.49.310, 15.49.370(3) and chapter 17.24 RCW. WSR 00-24-077, § 16-302-025, filed 12/4/00, effective 1/4/01.]



16-302-030
Standards for production of foundation seed.

The general seed certification standards together with specific crop standards established in this chapter constitute the basic standards for production of foundation seed as deemed necessary by the certifying agency. Seed to be eligible for foundation certification tags, or OECD basic tags, must be approved by the originating plant breeder or his designated agent, and in compliance with the following standards:
(1) Preplanting report. A preplanting inspection, an industry responsibility, must be made of fields to be planted with breeder seed. A written report of the preplant inspection, performed by either a representative of the person issuing the contract or by the grower must be maintained by the variety owner or designee for a minimum of three years. The report shall show the grower's name, number of acres, location, crop history for the past three years, crops to be planted, origin of breeder seed, isolation status, and weed and crop present.
(2) Planting requirement. To distinguish between any possible volunteer and the crop seeded, all fields must be planted in distinct rows. Plants outside defined rows may be construed as volunteers.
(3) Combine inspection. The combine used for seed harvesting must be cleaned and inspected prior to harvesting foundation or OECD basic seed. The combine must be free of all contaminating material. If an official combine inspection is requested, the certifying agency must be notified of the following: The date, time, and location where the combine inspection may be made.
(4) Processing plant inspection. The processing or conditioning plant must be inspected before processing foundation or OECD basic seed and periodic inspections will be made during processing by the processor.
(5) Recleaning, rebagging, preinoculation, treating, or other processes must be approved by the certifying agency. An original tag must be submitted with the request for recertification and the seed must be retagged and resealed on completion.
(6) For a proprietary variety the above combine inspection (subsection (3) of this section), and processing plant inspection (subsection (4) of this section), responsibility may be assigned to the proprietor or his designee upon their request. The variety owner or designee must maintain a report covering required inspections.
[Statutory Authority: RCW 15.49.005, 15.49.081, 15.49.310, 15.49.370(3), and chapter 34.05 RCW. WSR 14-20-050, § 16-302-030, filed 9/25/14, effective 10/26/14.

Limitation of generations for seed certification.

The number of generations through which a seed variety may be multiplied is limited to the number specified by the originating breeder or owner of a variety except that:
(1) Unlimited recertification of the certified seed class may be permitted for crop varieties where foundation seed is not being maintained.
(2) The production of an additional generation of the certified class may be permitted on a one-year basis when:
(a) Prior to the planting season, the certifying agency states that foundation and registered seed supplies in the United States are not adequate to plant the needed acreage of the variety.
(b) Permission of the originating breeder and/or owner of the variety is obtained (if applicable).
(c) The additional generation of certified seed produced is declared to be ineligible for recertification.
[Statutory Authority: RCW 15.49.005, 15.49.081, 15.49.310, 15.49.370(3) and chapter 17.24 RCW. WSR 00-24-077, § 16-302-035, filed 12/4/00, effective 1/4/01.]

Responsibilities when participating in the seed certification program.

All participants in the seed certification program must:
(1) Maintain the genetic purity and identity during seeding, growing, harvesting, and postharvest storage, and ensure reasonable precaution is taken to control contaminating crops and varieties, noxious weeds, and seed-borne diseases.
(2) Prevent seed crop and lot mixture when harvesting.
(3) Identify the seed crop as it is delivered to the processor with the assigned field number or numbers.
(4) Clean the seed crop at a seed conditioner approved by the department under WAC 16-302-125. A list of approved seed conditioners may be obtained from the department seed program.
(5) Comply with standards and procedures for seed certification under the authority of chapter 15.49 RCW and rules adopted thereunder.

Land history—Seed certification.

Land requirements for seed certification are as established in the specific seed crop standards. When a cultural practice has proved to be successful, requirements may be modified upon written approval of the seed certifying agency. Cultural practice may include any of the following:
(1) Mechanical means such as deep plowing.
(2) Chemical means such as fumigants.
(3) Other material for seed bed preparation. Materials and methods must be a matter of record. Any practice used must be adequate to ensure varietal purity and must be approved in writing by the certifying agency. Any deviations from established land requirements must be submitted in writing to the certifying agency.

16-302-070
Seed field inspections by the certifying agency.

The certifying agency conducts field inspections as follows:
(1) A seedling field is inspected at the most appropriate time after receipt of seedling application. If the field produces seed the same year of planting, a seedling producing inspection is made prior to harvest.
(2) Each year a crop of certified seed is produced, field inspections are made at a time when factors affecting certification are most evident.
(3) The unit of certification is defined as the entire field standing at the time of inspection. A portion of a field may be certified if the area to be certified is clearly defined by flagging, stakes or other visual means. The border area of the field is considered the unit of certification if it is planted to the same crop and is inclusive of the acreage applied for.
(4) The unit of inspection may include areas adjacent to a field or areas of surveillance if these areas contain factors that would impact the certification eligibility of the seed crop as defined in the specific crop standards. Such factors may be, but are not limited to, contaminating pollen sources, weeds, jointed goatgrass, jointed goatgrass hybrids or other crop.

16-302-075
Tolerances stated as "none found."

A tolerance of "none found" for contaminating or diseased material in either field or clean seed standards means that none was found during the normal procedure of field inspection or seed sample testing. None found does not constitute a guarantee that the field or seed is entirely free of the contaminant or disease.
[Statutory Authority: RCW 15.49.005, 15.49.081, 15.49.310, 15.49.370(3) and chapter 17.24 RCW. WSR 00-24-077, § 16-302-075, filed 12/4/00, effective 1/4/01.]



16-302-080
Seed fields ineligible for seed certification.

(1) A seed field is not eligible for certification unless a field inspection is made prior to defoliation or harvesting.
(2) Prohibited noxious weeds must be controlled to prevent seed formation, with the exception of jointed goatgrass or jointed goatgrass hybrids, the presence of which in "small grain" fields will be cause for rejection. Follow-up inspections may be conducted to ensure weed control was sufficiently carried out to prevent prohibited noxious weed seeds from being harvested with the seed crop. Excessive objectionable weeds may be cause for rejection of a seed field. Excessive weeds, poor stands, lack of vigor, or other conditions which make inspection inaccurate may be cause for rejection. A field producing foundation or registered seed that warrants a rejection because of noxious weeds may be reclassified to certified blue tag class if upon reinspection the field meets certified blue tag standards.
(3) If a seed field is rejected for certification, the grower may reapply to the certifying agency and pay a fee for reinspection after the cause for rejection is corrected, unless otherwise specified in chapter 16-302 WAC. No more than two reinspections are permitted for each field per year.

SamplingMethods used in the sampling, inspecting, testing, analyzing and examining seed for certification.

(1) The terms used in seed testing and the methods of sampling, inspecting, analyzing, testing and examining seed for certification are those adopted by the AOSA as shown in WAC 16-301-010. Other testing methodologies such as, but not limited to, genetic testing may also be used to determine certification eligibility.
(2) The entire lot of seed must be cleaned, the quantity defined, and in condition for sale at the time of sampling, except for ryegrass, which may be sampled under the early sampling program as allowed in WAC 16-302-091.
(3) The department shall obtain a representative sample for laboratory analysis of each lot of seed for certification. The sample shall be taken in accordance with official sampling procedures. Official sampling procedures are as follows:
Seed in bags.
(a) When more than one core is drawn from a bag, follow different paths. When more than one handful is taken from a bag, take them from well-separated points.
(b) For lots of one to six bags, sample each bag and take a total of at least five cores or handfuls.
(c) For lots of more than six bags, sample five bags plus at least ten percent of the number of bags in the lot. Round numbers with decimals to the nearest whole number. Regardless of the lot size, it is not necessary to sample more than thirty bags.

Program for early sampling of ryegrass.

The procedure for participating in the program for early sampling of ryegrass is as follows:
(1) Any company participating in this program must submit a report to the seed program listing the grower, acreage, variety, and field number of each field to be enrolled. This report must be filed by June 15th of each year. For fields that are in their second year of production or beyond, all lab numbers of tests from the previous year must also be provided.
(2) The seed company is responsible for having their field personnel sample each field in the windrow. The sample must be obtained from well-distributed points throughout the field. It is recommended that samples be thrashed and cleaned prior to testing. An additional fee will be charged for samples that are not cleaned. Samples must be forwarded to the seed program with the following information: The crop and variety, field number, grower, the name of the seed company, and a request for germination and fluorescence test. The sample must also indicate that it is being submitted under the early sampling program for ryegrass.
(3) At the time of conditioning the seed, a composite sample must be submitted to the seed program for purity testing. The sample information must indicate the seed is from a field under the early sampling program for ryegrass. In addition to providing complete certification information, the lab number on which the fluorescence test was conducted must also be provided. The seed program may run a fluorescence test on the composite sample to verify the results from the early sample.
(4) Certification tags will be issued upon completion of all required testing meeting the minimum certification standards for ryegrass. A tagging request must be filed with the seed program.
(5) Failure to comply with the requirements of this section will result in the disqualification of the seed company from the early sampling program for the year.

16-302-170
Other considerations in applying the standards for certification.

(1) Any crop certification standard, with the exception of germination that is expressed as a percent will be derived from a test based on the minimum weight for purity analysis as specified in the 2013 AOSA rules for that crop unless otherwise specified in rule.
(2) Any crop certification standard that is based on a number per pound will be derived from a test based on the minimum weight for noxious weed seed examination as specified in the 2013 AOSA rules for that crop unless otherwise specified in rule.
(3) For species that have a high rate of inherent dormancy, it will be acceptable to use the percent of total viability instead of germination percentage for certification only. State and federal seed laws require seed be labeled on a germination test.
(4) For species or varieties that contain GMO (genetically modified organism) traits, herbicide resistant traits, or other novel traits, each seed lot may be required to meet minimum trait standards as defined by the breeder or trait owner. The variety description must define the trait. To determine the level of trait present, a test such as PCR (polymerase chain reaction) or specified bioassay test may be required. If a test is not otherwise available the variety owner must provide testing protocols to the department.

Distance required from fields planted with:
Fields less than five acres
Fields five acres or more
Foundation

75 feet
45 feet
(3) In cases where an adjoining field is planted with a different variety of alfalfa, or alfalfa of a lower class, isolation may be obtained by measuring off the required strip in the certified seed crop field. This isolation strip may be mowed for hay or it may be harvested for uncertified seed under the following conditions:
(a) The grower must apply for certification of the entire alfalfa seed field and clearly stake off the isolation strip. The entire field must pass all certification requirements, except for isolation at time of inspection. The field report will show rejection due to lack of isolation.
(b) The grower must harvest and deliver to a department approved conditioning plant the seed from the certified portion of the field separately from the seed from isolation strip. After the seed is weighed and lotted in, the weight of the seed from the isolation strip is to be reported to the seed program. At this time the seed program records will indicate the field has passed certification.
(4) Isolation is not required in an alfalfa seed field producing certified class seed when the isolation zone is less than ten percent of the entire field being certified if there is a clear ten-foot line of demarcation between adjacent varieties. The isolation zone is the area calculated by the length of the common border with other varieties by average width of the certified field falling within the one hundred sixty-five-foot isolation distance requirement.

(2) Foundation corn single crosses:
(a) Foundation single cross. A foundation single cross must consist of the first generation of a cross between: Two inbred lines; an inbred line and a foundation back cross; or two foundation back crosses.
(b) Foundation back-crosses:
(i) A first generation foundation back cross must be the first generation cross between a foundation single cross of related inbred lines and an inbred line which must be the same as one of the inbreds in the foundation single cross.
(ii) A second generation foundation back cross must be made by using a first generation back cross as the seed parent and the pollinating parent shall be an inbred line. The inbred line must be the same as the inbred parent used in making the first generation back cross seed parent.
(c) A male sterile line may be substituted for its fertile counterpart as one parent of a foundation single cross if the male sterile line has been backcrossed for not less than five generations to its fertile counterpart, or the male sterile line is the same in other characteristics as its fertile counterpart.
(d) Male sterile lines propagated by hand pollination will be are eligible for certification.
(e) A pollen restoring line may be substituted for its nonrestoring counterpart in a foundation single cross if the pollen restoring line is the same in other characteristics as its nonrestoring counterpart.
(3) Hybrid corn seed:
(a) Hybrid corn seed is seed to be planted for the production of feed or for use other than seed. It may be any one of the following:
(i) Double cross - The first generation cross between two foundation single crosses.

(b) Foundation single cross seed and foundation back cross seed planted for the production of double cross, single cross, or three-way cross hybrid corn seed must be completely certified by a recognized seed certifying agency.
(c) Inbred line seed planted for the production of single cross or three-way cross hybrid corn seed to be used for grain or forage production must meet the requirements for the definition of an inbred line (as provided for in subsection (1)(b) of this section) and be certified.
(d) Only the class "certified" is recognized.
(4) Inbred seed and the seed of each parent for single crosses must meet one of the following requirements:
(a) Be in the hands of the originator;
(b) Be a line obtained directly from the originator;

Field standards for corn seed certification.

Except for hybrid corn field standards for corn seed certification are:
(1) Corn seed isolation requirements are:
(a) An inbred must be so located that it is not less than 660 feet from other corn except when the inbred is grown as a pollinator in a single cross production field. Any ear parent(s) in the same isolated field must be entered for certification, inspected, and meet all field requirements for certification.
(b) A specific foundation single cross must be located so the seed parent is not less than six hundred and sixty feet from other corn for pollinator rows and other seed parent(s) in the same isolated field. All seed parent(s) in the same isolated field must be applied for certification, inspected, and meet all field requirements for certification.
(c) Differential maturity dates are permitted for modifying isolation distances for inbred lines or male sterile inbred line increases if there are no receptive silks in the ear or seed parent at the same time pollen is being shed in the contaminating field.
(d) Foundation inbred or single cross production fields of dent sterile popcorn need not be isolated from yellow dent field corn.
(e) Corrections for improper isolation must be made by one of the following methods:
(i) By completely destroying or by detasseling the necessary contaminating corn before silks appear in the ear or seed parent in the field to be certified; or
(ii) By completely destroying the plants which are improperly isolated from the contaminating corn before the final field inspection.
(2) For corn single crosses, nine feet is the maximum distance a seed parent row must be from a pollen parent row.
(3) For corn single crosses, the minimum population of pollen shedding plants per acre is two thousand. Ineffective pollen parent plants must not be counted.
(4) Corn single cross fields being inspected for certification must contain not less than four hundred pollen plants per acre that are actively shedding pollen when more than twenty-five percent of the seed parent silks are apparently receptive.
(5) Corn single cross detasseling or pollen control. More than five percent of the seed parent must have apparently receptive silks for the following provisions to apply. Apparently receptive silks are emerged silks which are not wilted or brown.
(a) An isolation of a specific foundation single cross is not accepted for certification if at one inspection more than one-half percent of the stalks of the seed parent have shed pollen, or if the total number having shed pollen on any three days of inspection exceeds one percent.
(b) Cytoplasmic male sterile seed parent plants; detasseling (cutting or pulling) to control plant pollen is permitted.
(6) Corn field roguing:
(a) Definitely off-type plants must be destroyed completely so that suckers do not develop. Plants showing definite hybrid vigor or a definitely different type from the inbred or parent being inspected are classified as definitely off-type.
(b) For inbred lines, an isolation in which more than one-tenth of one percent (one per one thousand) of definitely off-type plants have shed pollen, when at the same time more than five percent of the plants have apparently receptive silks, is not certified.
(c) For single crosses, an isolation in which more than one-tenth of one percent of definitely off-type plants are present in the seed parent, when the silks have turned brown, is not eligible for certification.
(d) Sucker tassels and portions of tassels of off-type plants is counted as shedding pollen when two inches or more of the central stem, the side branches, or a combination of the two has the anthers extended from the glumes.

16-302-295
Field standards for hybrid corn seed certification.

Field standards for hybrid corn seed certification are:
(1) Hybrid corn seed isolation:
(a) A specific hybrid must be located so that the seed parent is not less than six hundred and sixty feet from corn of a different color or texture with the following exceptions:
(i) Hybrid seed production fields of dent sterile popcorn need not be isolated from yellow dent field corn; or
(ii) When the contaminating corn is of a different color or texture aggregating less than one-fourth acre on one exposure, the isolation distance may be modified in accordance with the table listed in this section.
(2) A specific hybrid corn must be located so that the seed parent is not less than four hundred and fifteen feet from other corn of the same color or texture. The planting of pollen parent border rows and the size of the crossing field according to the following table may modify this distance.

Different dates of planting will not divide a field for isolation purposes but may divide the field for detasseling inspection.
(a) The border rows and pollen parent rows must be planted with certified first generation seedstock, must be shedding pollen simultaneously with silk emergence of the seed parent and must not be separated from the seed parent by more than thirty-three feet.
(b) A field planted with the same eligible pollen parent may be used as an isolation buffer if it is applied for certification, inspected and meets field requirements for certification.
(c) Full credit is not given where poor stands of border corn exist, where the border rows have been detasseled, or where, for any reason, the border rows are not shedding pollen as plentifully as the pollen parent rows. Because of the difficulty of obtaining and maintaining a good stand of corn, the planting of more than the minimum number of border rows is recommended.
(d) The maximum distance a seed parent row shall be from a pollen parent row is fifteen feet.
(3) Corrections for improper isolation of hybrid corn must be made by one of the following methods:
(a) By completely destroying or by detasseling the necessary contaminating corn before silks appear in the seed parent in the field to be certified; or
(b) By completely destroying the seed producing plants that are improperly isolated from contaminating corn before the final field inspection.
(4) Hybrid corn detasseling or pollen control. More than five percent of the stalks of the seed parent must have apparently receptive silks for the following provisions to apply. Apparently receptive silks are emerged silks which are not wilted or brown.
(a) An isolation is not accepted for certification if upon inspection by the certifying agency more than one percent of the stalks of the seed parent have shed pollen, or if the total number having shed pollen on any three days of inspection exceeds two percent.
(b) When more than one combination of hybrid corn is grown in the same isolation and the seed parent of one or more is shedding pollen in excess of one percent, all seed parents having five percent or more apparently receptive silks at the time is disqualified for certification unless adequately isolated from the shedding seed parent.
(c) Sucker tassels and portion of tassels are counted as shedding pollen when two inches or more of the central stem, the side branches, or a combination of the two have the anthers extended from the glumes.
(5) A male sterile seed parent may be used to produce certified hybrid corn seed by either of two methods:
(a) Seed of the normal fertile seed parent is mixed with the seed of the male sterile seed parent of the same pedigree either by blending in the field at harvest or by size at conditioning time. The ratio of male sterile seed parent seed to normal seed parent seed does not exceed two to one.
(b) The male parent involves a certified pollen restoring line or lines so that not less than one-third of the plants grown from the hybrid corn seed produce pollen that appears to be normal in quantity and viability.
(6) Hybrid corn roguing:
(a) Definitely off-type plants in a parent line planted for the production of single cross or three-way cross hybrid corn seed to be used for grain or forage production must be completely destroyed so that suckers do not develop.

This isolation strip may be mowed for hay or it may be harvested for uncertified seed under the following conditions:
(a) The grower must apply for certification of the entire red clover field and clearly stake off the isolation strip. The entire field must pass all certification requirements, except for isolation at time of inspection. The field report will show rejection due to lack of isolation.
(b) The grower must harvest and deliver to a department approved conditioning plant the seed from the certified portion of the field separately from the seed from the isolation strip. After the seed is weighed and lotted in the weight of the seed from the isolation strip is to be reported to the seed program. At this time the seed program records will indicate the field has passed certification.

16-302-560
Miscellaneous field and seed inspection standards for buckwheat, chickpea, field pea, lentil, millet, soybean, sorghum, small grain seed certification.

(1) Field inspection timing for buckwheat, chickpea, field pea, lentil, millet, soybean, sorghum, small grain seed entered in the certification program are:
(a) For field pea and lentil - When seed crop is in full bloom;
(b) For chickpea (garbanzo bean) - When seed crop is mature enough to differentiate leaf type (compound or simple leaf type), with a second inspection occurring between full bloom and late pod stage for registered and foundation class. Certified class requires a second inspection at late pod stage if ascochyta blight is observed during the first inspection;
(c) For soybean - When seed crop is in full bloom and of mature color;
(d) For open pollinated sorghum - When seed crop is in full bloom, and optionally again when seed crop begins to show mature color;
(e) For hybrid sorghum - Two inspections during bloom and one inspection after seed begins to show mature color;
(f) For small grains - When seed crop is fully headed and of mature color;
(g) For millet - One inspection during bloom and one inspection after seed begins to show mature color; and
(h) For buckwheat - One inspection when seed crop is in full bloom.
(2) Any condition or practice which permits or causes contamination of the seed crop, such as failure to prevent seed formation of prohibited noxious weeds, or excess weeds including excessive objectionable or restricted noxious weeds, or mechanical field mixing, is cause for rejection upon inspection. Fields rejected for jointed goatgrass or jointed goatgrass hybrids are not eligible for reinspection and must remain ineligible for any production of certified classes of small grain seed until a reclamation procedure, as specified in subsection (3) of this section has been completed. Fields rejected for other causes will remain eligible for reinspection.
(3) The jointed goatgrass reclamation procedure includes the following:
(a) Each grower must develop a reclamation plan for his/her affected fields. The plan must be based on the most current recommendations of Pacific Northwest scientists and Washington State University cooperative extension as well as good management practices. The plan may include use of certified seed, spring cropping practices, and late tilling and planting. No particular program is specified or endorsed and compliance with a program does not assure eligibility for the production of certified classes of small grain seed. Eligibility is based solely upon results of field inspections as provided in (b) through (e) of this subsection.
(b) The rehabilitation and inspection program duration is three years for irrigated land and five years for dryland without production of certified small grain seed and the first year of certified seed production thereafter.
(c) Annual inspections of the affected fields are conducted by the certifying agency during the prescribed rehabilitation period at such time that the jointed goatgrass or jointed goatgrass hybrids would be most visible.
(d) Following the prescribed period of rehabilitation and during the first certified seed production year, a minimum of three field inspections are conducted by the certifying agency.
(e) If jointed goatgrass or jointed goatgrass hybrids are found during any inspection as provided in (c) and (d) of this subsection, the rehabilitation program is determined unsuccessful or the field is declared ineligible and the rehabilitation and inspection program for that field must begin again at year one of the procedure.
(4) Field run lots of seed of the same variety may be commingled to facilitate storage and conditioning.
(5) No prohibited noxious weed seeds are permitted upon inspection for seed standards.
(6) Germination minimum refers to germination when sampled.
(7) If chemically controllable seed-borne diseases are noted upon inspection for field standards and seed standards for small grains, treatment of seed is required.
(8) Wild oat, isolated patches and borders must be removed or clearly marked so as to avoid harvesting with the rest of the field. If rejected, a reinspection is necessary to assure clean-up efforts are satisfactory. Spot checks are conducted on fields where heavy patches or contaminated borders were noted. Harvesting these areas with the rest of the field is cause for rejection of the entire field.
(9) The official laboratory providing seed analysis for the purpose of certification is the department.
(10) For all fields planted with varieties that contain the CLEARFIELD trait as defined in the variety description, documentation will be required to be submitted with the certification application verifying that the production field meets all production guidelines and was sprayed with the appropriate herbicide. CLEARFIELD is a trait that makes a plant resistant to the Imazamox herbicide.

Isolation requirements for industrial hemp seed certification.

Isolation requirements for industrial hemp seed production are as follows:
(1) Isolation areas must be kept free of any harmful plants that can cause contamination. Not more than one plant per eleven square feet of harmful contaminants (species that can cross pollinate with the inspected crop) is permitted within the required isolation distance(s) adjacent to the inspected crop. The conditions of each crop are assessed by the department, which may alter this standard, usually by reducing the number of contaminant plants permitted per square yard, according to identified contamination risks.
(2) Foundation, registered and certified industrial hemp must be isolated from any marijuana production licensed by the liquor and cannabis board by a distance of fifteen miles.
(3) Industrial hemp seed production crops for certification must be isolated from all other industrial hemp varieties or fields not meeting the varietal purity requirements for certification as follows:

Field inspection standards and tolerances for industrial hemp seed certification.

(1) Industrial hemp seed production crop fields shall be inspected by the department in three stages.
(a) The first inspection should be conducted before female (pistillate) flowers of the inspected crop are receptive and after the formation of male (staminate) flowers before pollen is shed.
(b) The second inspection should be conducted during the receptive stage of the female plants in the inspected field, normally within three weeks of first inspection.
(c) The third inspection should be conducted within ten days prior to harvest. The grower must notify the department of anticipated harvest date. Fields not harvested within ten days of the third inspection will require an additional inspection and THC test.
(d) Isolation areas will be inspected for volunteer plants and harmful contaminants at each department inspection.
(2) Off-type male flowers must be removed by the grower prior to producing pollen and evidence of removal must be identifiable during the department's crop inspection.
Rogued male flowers must be removed from the field and buried or otherwise destroyed by the grower to prevent pollen production.
(3) If dioecious male plants start flowering before removal from field, all plants around them must be destroyed by the grower within a radius of ten feet for foundation seed, six feet for registered seed and three feet for certified seed.
If dioecious male plants or if other off-type male flowers are found to be shedding pollen during any inspection, an additional inspection will be required within seven days to verify adequate control of detrimental pollen. An additional reinspection fee will be assessed by the department.
(4) Plant samples will be taken by the department for THC testing at the third inspection. Test results in excess of 0.3% THC will be cause for rejection and the field may be subject to destruction.
The seed crop for certification may be harvested after the third inspection and the THC sample has been submitted for testing. However, no seed or other industrial hemp by-products may be transported off of the registered land area until THC testing with a result of 0.3% THC or less has been received and a release notice to the grower has been issued by the department.
(5) Intersexual plant type ratios shall not exceed the limits when defined in the variety description by the breeder.
(6) Excessive weeds or other factors that prevent varietal purity and identity determination shall be cause for the department to reject the affected field for certification purposes.
(7) Fields planted in such a manner that prevents inspector access shall be cause for the department to reject the affected field for certification purposes unless the grower remedies the condition in a timely manner as required by the department.
(8) Maximum impurity standards must not be exceeded based on six replicated counts of ten thousand plants according to the following table:
 
Maximum impurity standards per 10,000 plants
 
Maximum number of "too male" monoecious plants
Maximum number of dioecious male plants shedding pollen
Maximum number of other impurities including other varieties
