Learn how to accurately stage corn when lower leaves have dropped off, so you can stay on-label with herbicide applications and keep plants healthy through the season. In this Agronomy Moment episode, Wendell Koehn and agronomist Celena walk through a simple, field-ready method to confirm growth stage from V5 to V7 using a dug plant on the tailgate.

  • Why accurate corn staging matters for herbicide labels and management decisions
  • How to dig, split, and read internodes to confirm V5, V6, and V7
  • What to look for at the crown and soil line when staging
  • When dark or discolored crowns might signal fusarium or other issues
