1 None of the Prohibited Weed Seeds listed in Section V in the OSCS Handbook, nor St Johnswort is allowed.

Restricted weed seed tolerances as indicated for each crop, allows one seed to be found in the Noxious weed seed exam working sample [ref. 1 lb = 453.6 grams], and applies to the following species: Corn bedstraw, Buckhorn plantain, Docks, Sheep sorrel. In no crop, may Corn Bedstraw exceed 45 per pound, as per Restricted Noxious Weed Seed Tolerances [OAR

603-056-0205]. Seed testing of all PVG species, including tree and shrub species, will include both a purity working sample and a noxious working sample.

2 For purposes of seed testing and the use of the ammonia test (see OSCS Certification Handbook, Section IX Definitions, D3 Ammonia Test), Idaho fescue and Roemer’s fescue are included in the Festuca ovina aggregate; accordingly these species will be examined with the ammonia test for incidental seeds of Chewings and Red fescue.
