The following (a) - (p) are notes to the above table. | |
(a) | Not to exceed 0.25% other grass species for blue tag seed. |
(b) | Grass seed must not contain more than 45/lb. for registered seed 91/lb. for certified seed, singly or collectively, of objectionable weed seeds. (See (f) of this subsection for certified bentgrass and redtop exemption.) Grass seed shall be free of the seed of prohibited noxious weeds. |
(c) | A tolerance of 0.50% may be allowed for samples containing weedy Bromus spp. provided the total of all other weed seeds does not exceed 0.30%. |
(d) | A standard tetrazolium (two hundred seed) test may be used in lieu of germination test. NOTE: State and federal seed laws require seed be labeled on a germination test. |
(e) | A tolerance of 0.80% may be allowed in registered and certified wheatgrass containing small grain seed provided the total of all other crop seed does not exceed 0.10% for registered class and 0.50% for certified class. |
(f) | Certified seed must not contain over 907 seeds per pound, singly or collectively, of the following weeds: Plantago spp., big mouse-ear chickweed, yarrow, spotted cat's ear, and dandelion. |

(n) | Total viability as allowed in WAC 16-302-170 can be substituted for germination percentage. |
(o) | Turf type fescues 97% pure seed. Range/reclamation types 92% pure seed. Varietal designation of turf or range/reclamation types is to be made by the breeder or variety owner. If no designation is made, the variety will be considered a turf type. |
(p) | 10% slender wheatgrass is allowed in the certified class of Critana and 5% Elymus species allowed in the certified class of Schwendimar, provided that the total of all other grass species does not exceed 0.25% and total other crop, including all other grass species does not exceed 0.50%. |
