The Missouri Department of Agriculture (MDA) Plant Industries Division, Seed Regulatory Program regulates the state’s commercial seed industry through inspecting firms, sampling and testing seeds and providing information to consumers to assist in making buying decisions. These inspections are intended to prove the reliability of labelers in meeting their claims for seed quality.

All seed retailers are required to have their seed retested for germination every 10 months (counting the month the seed was retested). Seed lots found to be out of test date will be placed on stop sale order until the seed has been retested and a new test date and germination rate is placed on the label or the seed is disposed of in an acceptable manner.

The Bureau of Feed and Seed offers many seed sampling and seed testing services. The charges for analysis and analytical reports on seed samples are listed in the Missouri Seed Regulations 2CSR 70-35.050.
