Corn and soybeans continue to grow rapidly across Iowa as heat and humidity push development forward. Across much of the region, corn is tasseling or nearing tassel, while soybeans are reaching key reproductive stages. This week, our agronomy team shares boots-on-the-ground insights on fungicide timing, disease pressure, insect activity, and what growers should watch as application season ramps up.

In this episode, the team discusses:

• Corn tasseling progress across Iowa
• Soybean growth stages and identifying the R3 fungicide timing window
• Gray leaf spot, common rust, eyespot, bacterial leaf streak, and early tar spot concerns
• Western corn rootworm beetle emergence and scouting reminders
• Fungicide timing recommendations for corn and soybeans
• One-pass versus two-pass fungicide strategies
• Disease pressure and how weather conditions influence development
• Ground rig, drone, and aerial application considerations
• Heat, humidity, and plant uptake during fungicide applications
• The importance of field-by-field evaluation before making application decisions

Featured this week:
