Seed Testing
FAQ
What is the purpose of the MCIA Seed Laboratory?
The MCIA Seed Laboratory tests seed for quality. It conducts germination, physical purity (including inert, other crop, and weed contaminant percentages) and noxious weed seed exams, varietal verification, vigor, tetrazolium (TZ), and herbicide bioassay tests, as well as other crop-specific tests.
The MCIA Seed Laboratory is accredited by the USDA Accredited Seed Laboratory (ASL) Program and is Process Verified for germination, physical purity and noxious-weed seed examinations for species contained within the AOSA Rules for Testing Seeds and/or the Federal Seed Act.
The MCIA Seed Laboratory is also officially recognized by the Canadian Food Inspection Agency (CFIA). The Laboratory can grade seed lots destined for marketing in Canada to establish a Canadian pedigreed grade name.
Who determines how seed is tested?
The MCIA Seed Laboratory follows testing rules established by the Association of Official Seed Analysts (AOSA). The AOSA Rules for Testing Seeds, used by regulatory agencies and commercial labs throughout the U.S., standardizes seed testing procedures for numerous species. Other rules may be applied when testing seed intended for export to foreign markets, such as Canada.
Why should my seed be tested?
Seed testing is one of the final steps in the seed certification process. Test results will be used to verify that standards have been met for a particular crop and seed class. MCIA requires seed lots it certifies to be tested at the MCIA Seed Laboratory, except for native species, which may be tested at an authorized lab. Testing information can also be used for labeling and/ or quality assurance. Service testing is also available for seed that is not in the certification program. A host of tests offered, including germination, vigor, purity, and moisture, can help a seed producer, seller, or buyer assess seed quality.
How do I submit samples?
Sample bags are available from the MCIA Office for submitting your samples. Fill the bag with a representative sample to the top line for large seeded agronomic crops, and to the middle line for most natives, grasses, and small-seeded legumes. Include an MCIA Sampling Report, available on our website or from the MCIA Office, providing seed lot information and indicating the tests to be conducted on your sample.
What should I look for after seed is tested?
Seed tested as part of certification will receive a Seed Certification Report, indicating the test results and a passed or failed lot status. Preliminary samples, carryover seed, and non-certified seed will receive a Laboratory Report of Analysis, which will indicate the results of the tests requested. You can receive preliminary and final results by e-mail, and a final report will be mailed to you.
