2. B. Production Requirements. To be eligible for the production of all certified classes, plots and containers/tanks shall be left undisturbed for a minimum of four weeks prior to planting, and found to be free of sea oats and noxious and objectionable weeds.

   1. 1. Plot Requirements

      1. a. Only one variety of sea oats shall be grown per plot.
      2. b. Plots of different varieties must meet the minimum isolation distance at all points.
      3. c. All seed heads shall be routinely removed from plants after flowering begins to ensure viable seed are not produced.

   2. 2. Container/Tank Requirements

      1. a. Soil used for container/ tank production shall:

         1. i. come from an area that has not produced sea oats for a minimum of one year
         2. ii. be free of visible sea oats rhizomes and stems prior to transplanting.
      2. b. Only one variety of sea oats shall be grown per production tank.
      3. c. Different varieties shall be grown in separate tanks units unless individual varieties are separated by solid sided partition that will not allow rhizomes or stem material to spread between or within tank units.
      4. d. All seed heads shall be routinely removed from plants after flowering begin to ensure viable seed are not produced.
3. C. Grower Inspections. Plots and containers shall be routinely inspected by grower to ensure that all requirements of this Section are being met.

4. D. LDAF Inspections. Production plots and containers/tanks shall be made accessible for inspection by the grower.

   1. 1. Plots and containers/tanks shall be inspected by LDAF within four weeks prior to transplanting to ensure they are free of volunteer sea oat plants and noxious and objectionable weeds.
