As an Accredited Lab of the International Seed Testing Association (ISTA), the OSU Seed Lab is authorized to issue ISTA certificates. This service begain in June 2009.
Blue Certificates are test reports for seed samples. They do not represent a seed lot; therefore, sampling is the responsibility of the customer. We can issue these certificates on any sample, regardless of origin or lot location.
Orange Certificates are test reports that represent whole seed lots. To ensure that the certificate accurately represents the seed lot, the lab is responsible for both sampling and testing. Our samplers are located in the Pacific Northwest region.
Here is some basic information to help get customers acquainted with the ISTA Certificate program.
