What the state seed corporations charge, variety by variety, with the date each rate took effect.
A seed rate is set by a schedule and holds until the next revision. It does not move daily, so this page shows an effective date instead of today's date. If the newest date below is months old, that is the rate still in force, not stale data.No schedule has been collected yet. A rate appears here only once a published schedule has been read, because guessing a seed rate between revisions would be inventing a number.
