AMENDATORY SECTION(Amending WSR 03-18-072, filed 8/29/03, effective 9/29/03)

WAC 16-302-410   Standards for sod quality seed.   (1) Except for ryegrass sod quality seed, seed standards for sod quality grass seed are as follows:

Variety	Minimum Purity	Minimum Germination	Maximum* Other Crop	Maximum** Weed
Kentucky Bluegrass	97%	80%	0.1%	.02%
Red Fescue	98%	90%	0.1%	.02%
Chewings Fescue	98%	90%	0.1%	.02%
Tall Fescue	98%	85%	0.1%	.02%

*	Must be free of ryegrass, orchardgrass, timothy, Agrostis sp., black medic, Poa trivialis, brome, reed canarygrass, tall fescue, clover, and meadow foxtail. Maximum allowable Canada bluegrass .02%. When the base sample is one of these kinds, the species will not be considered a contaminant (i.e., tall fescue in tall fescue).
**	Must be free of Big, Canby and Sandberg bluegrass, dock, chickweed, crabgrass, plantain, short-awn foxtail, annual bluegrass, velvetgrass, ((rattail fescue)) Vulpia sp., and noxious weed seeds as listed under WAC 16-302-100 and 16-302-105.

     (2) Seed standards for sod quality ryegrass seed are as follows:

Variety	Minimum Purity	Germination****	Other Crop*	Maximum Weed***
Ryegrass**	98%	90%	0.10%	.02%

*	Must be free of black medic, orchardgrass, timothy, Agrostis sp., Poa trivialis, brome, reed canarygrass, tall fescue, clover and meadow foxtail. Maximum allowable Canada bluegrass 0.02%.
**	Maximum fluorescence levels as determined by breeder or variety owner.
***	Must be free of Big, Canby and Sandberg bluegrass, ((rattail fescue,)) dock, chickweed, crabgrass, plantain, annual bluegrass, velvetgrass, Vulpia sp., short-awn foxtail, and noxious weed seeds as listed under WAC 16-302-100 and 16-302-105. An additional 0.07% of weedy Bromus spp. will be allowed.
****	85% minimum germination allowed on ryegrass varieties as designated by the breeder or variety owner. See list maintained by the seed program.

     (3) A sod seed analysis certificate is the basis of determining if a lot meets sod quality standards. This certificate is issued by the certifying agency and represents a purity analysis, a twenty-five gram noxious all weed all crop exam and a germination test, except a 50-gram noxious all weed all crop exam is required for fescues and ryegrass.

     (4) In addition to a seed certification tag, seed meeting sod quality certified seed standards will be tagged with a special "sod quality seed" tag.
