(1) Seed standards for quality timothy grass seed are as follows:
Minimum % Purity | Minimum Viability by Germination or TZ Test | Maximum % Other Crop (a) | Maximum % Weed (b) | |
Timothy seed | 97 | 85 | 0.20 | 0.02 |
Purity component percentages are based on 1 gram sample size. | ||||
(a) | Must be free of ryegrass, orchardgrass, 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 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.
