As of June 1, 2022, the Ohio Seed Improvement Association’s seed testing laboratory and COST lab have closed.  All Certified, Identity Preserved, and Quality Assurance seed lots still need a complete test with a varietal purity. A copy of the results needs to be sent to OSIA prior to any tags or certificates being issued. Below is our list of recommended seed labs. Please contact these labs for information on pricing and tests available.
