In this PCT Shorts agronomy update, Jonah Johnson answers one of the most common spring questions from wheat growers:

“Am I too late to spray my wheat?”

Many wheat fields remain greener than expected, even where nitrogen hasn’t been applied yet. Jonah explains how winter snowfall can deliver atmospheric nitrogen, sometimes providing up to 12 pounds of actual nitrogen per acre, helping support early wheat growth.

He also covers what really determines whether applications are still effective:

• ✅ How wheat growth stages impact nitrogen demand
• ✅ Why the jointing stage (GS6) is a key turning point
• ✅ The importance of flag leaf emergence (GS9) as the cutoff
• ✅ Whether nitrogen and sulfur applications still make sense
• ✅ What to consider before tank‑mixing herbicides or fungicides

For growers trying to make one‑pass spray decisions before head scab timing, this short video highlights what still works — and what may be too late.
