As an Accredited Lab of the International Seed Testing Association (ISTA), the OSU Seed Lab is authorized to issue ISTA certificates. This service began in June 2009.
Blue Certificates are test reports for seed samples. The certificate refers only to the seed sample, not the lot. Sampling is the responsibility of the customer. We can issue these certificates on any sample, regardless of origin or lot location. There is not a maximum lot size.
Orange Certificates are test reports that represent the entire seed lot. 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 and California.
Here is some basic information to help get customers acquainted with the ISTA Certificate program.
