  • Submit a Pre-Harvest Report to your county agricultural commissioner at least 45 days prior to the anticipated harvest date.
    • The name and contact information of your selected ISO 17025 accredited testing laboratory shall be included in this report.
  • The commissioner, or a third-party sampler designated by the commissioner, shall schedule a sampling date within 30 calendar days of the anticipated harvest date, but no later than 11 calendar days prior to the anticipated harvest start date listed on the pre-harvest report.
    • Any changes to the Pre-Harvest Report must be notified to the commissioner no less than 5 calendar days prior to the scheduled sampling date.
