State of Oregon: Seed Regulatory Program - Quality Tag Certification

The Oregon Department of Agriculture issues quality tags for seed lots that meet quality standards. Endophyte tags are issued for lots that meet tolerance standards for endophyte fungi as described in OAR 603-056-0170. Seed lots meeting sod quality standards established in OAR 603-056-0145 may be labeled as "Oregon Sod Quality Seed" using tags issued by the department.

Endophyte Tags

Endophyte tags can be requested by filling out and emailing the Endophyte or Sod Quality Tag Request Form to SeedServices@oda.oregon.gov. Include copies of test results with your application.
To be eligible for Endophyte tags, seed must be officially sampled and tested by the department and found to contain less than 5% endophyte fungi or their metabolites.
For sampling and testing requests, visit the Seed Sampling and Testing webpage.

Sod Quality Tags

Sod Quality testing can only be done by the Oregon Sate University Seed Laboratory. Visit their Oregon Sod Quality website for more information about their procedures.
Sod Quality standards for different seed kinds are established by OAR 603-056-0145 and are described in the table below.
To request Sod Quality tags, fill out the Endophyte or Sod Quality Tag Request Form and email completed forms and test results to SeedServices@oda.oregon.gov.

Kind	Minimum purity	Minimum germination	*Maximum 1 other crop**	*Maximum 5 weed**
Perennial ryegrass	98 %	90 %	0.10 % *2	0.02 %
Marion Kentucky bluegrass	95 %	80 %	0.10 % *3	0.02 %
Other varieties of bluegrass	97 %	80 %	0.10 % *3	0.02 %
Red fescue	98 %	90 %	0.10 %	0.02 %
Chewings fescue	98 %	90 %	0.10 %	0.02 %
Hard fescue	98 %	85 %	0.10 %	0.02 %
Sheep fescue	98 %	85 %	0.10 %	0.02%
Blue fescue	98 %	85 %	0.10 %	0.02 %
Bentgrass	98 %	85 %	0.10 % *4	0.10 %
Tall fescue	98.5 %	85 %	0.10 %	0.02 %

Must be free of ryegrass, orchardgrass, timothy, bentgrass, big bluegrass, poa trivialis, smooth bromegrass, reed canary grass, tall fescue, and clover. When the base sample is one of these kinds, the species will not be considered a contaminant (e.g. ryegrass in ryegrass).
Certification fluorescence levels and appropriate calculation will be applied when determining levels of other crop.
Maximum other varieties of Kentucky bluegrass allowed is 2%. Maximum allowed Canada bluegrass is 0.02%.
A 500-seed count will be used to determine other species of Agrostis.
Must be free of: dock, Rumex spp.; chickweed, Cerastium spp. or Stelloria media; crabgrass, Digitaria spp.; plantain, Plantago spp.; black medic, Medicago lupulina; annual bluegrass, Poa annua; velvetgrass, Holcus spp.; downy brome, Bromus tectorum, and other all-state noxious weed seeds, except Hawaii.
