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.
In this episode:
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
A practical example of using stress mitigation + fungicide to reduce late-season problems
If you’re walking fields and guessing between V6 and V7 from the row, this short episode shows you how to confirm the stage with confidence.
