What actually helps crops perform when conditions get tough?
In this From The Field episode, Dr. John Murphy joins Scott Bingman (AgXplore) and Barry Beaupre (Syngenta) in Southern Illinois to break down stress management, fungicide timing, PGR integration, and how growers are adapting to wet springs and variable crop stages.

If your field is a mix of V5 corn, spiking soybeans, and delayed emergence, this segment is for you.

🔑 What You’ll Learn:
🌱 1. Stress & Ethylene Management
Ethylene is the stress hormone that tells your plant to shut down early. Learn how late-season PGRs like GABA and choline chloride help reduce ethylene production and keep photosynthesis working through grain fill.

☔ 2. Adjusting for a Wet Planting Season
Illinois saw heavy early-season rain. That meant split planting dates and varying growth stages. Scott and Barry walk through how to approach nutrition, fungicide, and PGR applications when your corn is everywhere from emergence to V6.

🧪 3. Fungicide Strategy: One Pass vs Two
They answer the question: Is one fungicide pass enough? Learn how a two-pass system (V5–V8 and R1–R2) is outperforming in-season disease pressure from tar spot, southern rust, and more. It’s not just about staying clean—it’s about staying efficient.

🌾 4. Synergy in the Tank Mix
Build a better tank. Find out how Onward Max, boron, and modern SDHI fungicides like Miravis complement each other to support plant health and yield—without overcomplicating your application or sprayer setup.

📈 5. Nutrient Timing for Pod Set and Kernel Fill
Boron mobility and reproductive efficiency are front and center in this segment. Barry explains how to manage boron during critical pod set windows (R2–R3 in soybeans), and how corn benefits from late nitrogen and sulfur tied to tasseling.

🧠 Field-Proven Takeaways:
Tar spot and southern rust don’t wait. Symptoms lag behind infection, and by then, yield is already lost.

Soybean pods abort under stress. R2 is the moment to preserve flowers and set final yield—don’t miss it.

Photosynthesis = yield. The longer the plant stays green, the more potential you keep.

Plant growth regulators are not a buzzword. They’re real tools that support crop structure, hormone balance, and stress relief when the plant needs it most.

Two full-rate fungicide passes work. Especially in high-humidity regions like the southern Midwest, they’re becoming the new standard.

🎙 Bonus Insight:
Barry shares how decision-making changes across geographies—from his own experience in northern Illinois to Southern states where disease pressure hits harder and earlier. The takeaway? There’s no one-size-fits-all plan—but timing and intentionality always win.

Scott sums it up well:

“If we’re going to ask the plant to perform, we better give it what it needs—before it asks.”
