What information is required on a seed label?
A seed label must include specific information about the type and quality of the seed. Requirements vary depending on the kind of seed and its intended use.
Required label information
In general, seed is labeled with the following information:
- Kind and Variety
- Lot number
- Percentages of purity, other crop seed, weed seed, and inert matter
- Noxious weed seeds (by name and number per pound)
- Germination, dormant, hard seed, and total viable percentages
- Test date or "packed for"/"sell by" dates
- Origin of the seed
- Name and address of the labeler
Testing requirements
All label information must be based on seed tests (including purity exam, noxious seed exam, and germination testing) conducted according to Association of American Seed Control Officials (AOSA) Rules for Testing Seeds. All labels must indicate the presence of and number per pound for Prohibited and Restricted Weed Seeds (PDF).
Seed lots contaminated by Amaranthus species must be tested appropriately to determine whether they include Palmer amaranth (Amaranthus palmeri). This determination requires genetic testing.
Retail outlets that sell this seed must keep the original label provided by the seed labeler. Both the labeler and the retailer are responsible for ensuring that germination test dates are up to date on seed that is offered for sale.
Sales records and file samples
Seed labelers must maintain records, including:
- Seed test results
- Invoices for seeds purchased
- Invoices for seed sold
- A copy of the label
- A representative file sample of each seed lot
Seed types and labeling requirements
Agricultural Seed
Labeling Agricultural Seed (PDF) includes seed for:
- Grain and forage production
- Lawn and turf grass seed
- Native grass seed or mixtures intended for agricultural use
Native grasses, forbs, and mixtures
Labeling Native Seeds (PDF) used for conservation and restoration projects are considered agricultural seed but have some unique characteristics that have additional labeling considerations.
Vegetable and flower seed
Labeling Vegetable & Flower Seed (PDF) intended for home gardeners are typically sold in small packets. Labeling requirements differ from agricultural seed.
Tree and shrub seed
Labeling Tree & Shrub Seed (PDF) represents a smaller segment of the Minnesota seed business but has specific label requirements.
