	Minimum % Purity	Minimum Viability by Germination or TZ Test	Maximum % Other Crop (a)	Maximum % Weed (b)
Orchardgrass seed	90	85	0.20	0.02
Purity component percentages are based on 3 gram sample size.

(a)	Must be free of ryegrass, timothy, Agrostis sp., Poa sp., brome, reed canarygrass, tall fescue, and meadow foxtail.
	Must be free of the above listed contaminants based upon a 50 gram examination.
(b)	Must be free of alfilaria (redstem filaree), Bromus sp., chickweed including all other species in the Caryophyllaceae family, henbit, Poa sp., wild carrot, prohibited noxious weeds listed in WAC 16-301-045, and restricted noxious weeds listed in WAC 16-301-050.

(2) A quality orchardgrass seed analysis certificate is the basis of determining if a lot meets the quality orchardgrass seed standards. This certificate is issued by the certifying agency and represents a purity test, a 50 gram noxious, all weed, all crop exam, and a viability test.

(3) Seed meeting quality orchardgrass seed standards will be tagged with a "quality orchardgrass seed" tag.
