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 timothy seed analysis certificate is the basis of determining if a lot meets the quality timothy 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 timothy seed standards will be tagged with a "quality timothy seed" tag.
