How frequently are seed samples tested for purity and germination in California?

Seed samples in California are tested for purity and germination annually, which ensures that seed products meet quality standards and are suitable for planting. This regular testing helps to maintain the integrity of seed lots, confirming that they contain the correct species and varieties, as well as verifying their ability to germinate effectively. The annual testing requirement is crucial for protecting both consumers and agricultural practices, promoting a reliable supply of high-quality seeds needed for successful cultivation.

Testing only upon consumer complaint or at less frequent intervals, such as every two years, would not provide the same level of assurance regarding seed quality and could lead to widespread issues in agricultural productivity if subpar seed were sold or distributed. Therefore, the annual testing protocol aligns with the goals of regulating seed sales and ensuring quality in the marketplace, thereby supporting both growers and the overall agricultural system in California.
