WAC 16-302-091   What is the 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 ((window)) 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.

[Statutory Authority: RCW 15.49.005, 15.49.081, 15.49.310, 15.49.370(3) and chapter 17.24 RCW. 00-24-077, § 16-302-091, filed 12/4/00, effective 1/4/01.]

     (2) A person desiring to condition seed must make application to the department for a permit on a form provided by the department.

     (3) To obtain department approval for a seed-conditioning permit, the department conducts an inspection. A facility must show evidence that:

     (a) Seed for certification is handled in a manner which prevents mixture of lots of seed;

     (b) The seed conditioning facility is maintained and cleaned. Equipment must be easily accessible for cleaning and inspection, and must be cleaned between lots;

     (c) Each lot of seed is identified with a lot number;

     (d) Screenings are disposed of in accordance with chapter 15.49 RCW; and

     (e) Seed is sampled in accordance with WAC 16-301-095 ((and)), 16-302-090 and 16-302-091.

     (4) A seed conditioning facility must be approved by the department prior to handling seed for certification in bulk.

     (1) A blend data sheet, including proof of certification, verifying the origin and the certifying agency along with the analysis and pounds of each lot must be submitted to the certifying agency for approval.

     (2) Each lot of certified seed shall:

     (a) Meet standards acceptable to the certifying agency.

     (b) Be sampled under supervision of the certifying agency prior to mixing. The sample shall be obtained in accordance with official sampling procedures. The sample shall be identified with:

     (i) The verification of certification, origin, and certifying agency;

     (ii) The kind/variety;

     (iii) The analysis and size of lot.

     (3) The certifying agency reserves the right to:

     (a) Refuse permission to use individual lots;

     (b) Approve the equipment to be used and procedure to follow in mixing;

     (c) Approve the containers and labeling to be used; and

     (d) Sample the final mixture.

     (4) The certifying agency will identify each container with an official certification label verifying that the individual lots used were certified seed lots.

     (5) For a mixture to be labeled sod quality each component shall meet sod quality standards in WAC 16-302-410.

     (6) Fees for turf seed mixing shall be the same as the current blend fee. Refer to chapter 16-303 WAC for appropriate fees.

Foundation	Registered	Certified		75 feet

     (c) Isolation is not required in fields 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 feet) 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 feet isolation distance requirement.

     (d) A field eligible for the production of foundation, registered or certified seed must be isolated from classes of the same variety of apomictic (A) and self-fertile (S) species in accordance with the following requirements:

     (i) A field producing foundation or registered seed must be a minimum of fifteen feet from a field planted with a different class of the same variety.

     (ii) A field producing certified seed must be a minimum of five feet from a field planted with a different class of the same variety.

     (e) If it is not possible to provide minimum isolation distances for fields producing foundation, registered or certified seed exceeding five acres in area, border removal is permitted. Border removal requires removal of the portion of the field being certified that is adjacent to a contamination source. The following requirements apply if the grower uses border removal:

     (i) The minimum distances required for border removal are as follows:

	Minimum Isolation Distance Required for Fields Producing:
Border to be removed from the field being certified		Foundation	Registered	Certified
0 feet		900 ft.	300 ft.	165 ft.
15 feet		450 ft.	150 ft.	75 ft.

     (ii) The grower must apply for seed certification of the entire field and clearly stake off the border removal portion before inspection of the field by the certifying agency.

     (f) The border removal portion of the field may be harvested for uncertified seed under the following conditions:

     (i) 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.

     (ii) 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)) logged 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.

**	Refers to distance from other small grain fields. Foundation class fields must be isolated ninety feet from fields of the same genus. In addition, each rye field for certification must be isolated by three feet from fields producing a certified class of the same variety, and by six hundred sixty feet from other rye fields. Each triticale field for certification must be isolated by three feet from fields producing a certified class of the same variety, and by three hundred feet from other triticale, rye and wheat fields for foundation and registered class, and three feet for certified class, unless otherwise stated by plant breeder.
***	Refers to other small grains, except that no rye or triticale is permitted in barley, oat, or wheat; no vetch is permitted.

     (2) Small grains - seed standards:

Class	Foundation	Registered	Certified
Pure seed (min.)	98%	98%	98%
Inert (max.)	2%	2%	2%
off-type(*) (max.)	None found	2/lb	4/lb
Other small grain(*) (max.)	None found	1/lb	2/lb
Other crop(**) (max.)	None found	0.03%	0.05%
Weed seed (max.)	0.01%	0.01%	0.03%
Objectionable weed seed(***) (max.)	None found	None found	1/lb
Wild oat (max.)	None found	None found	None found (****)
Viability(*****) (min.)	85%	85%	85%

(*)	The combination of other small grain and off-type must not exceed 2/lb for registered class, and 4/lb for certified class. The tolerance for rye or triticale, is none found in barley, oat, or wheat. The tolerance for rye is none found in triticale. The tolerance for triticale is none found in rye.
(**)	Excluding off-type and other small grain. No vetch is allowed in small grain seed
(***)	Excluding wild oat.
(****)	1/lb for certified class oat.
(*****)	A certification certificate is issued upon receipt of either an official AOSA tetrazolium or germination test which meets minimum Washington viability standards. NOTE: State and federal seed laws require seed be labeled based on a germination test.

Note:

For all classes the purity analysis is based on 100 grams examined. For registered and certified classes, noxious weed, vetch, off-type, and other small grain((,)) determinations are based on 500 grams examined. For foundation class, noxious weed, vetch, off-type, and other small grain determinations are based on 1000 grams examined.
