Crop Talk by IAS – Field Scouting Update | June 17

Post applications are moving quickly as weather windows open, but field conditions continue to vary across Iowa and southwest Wisconsin. What we’re seeing in the field right now is a mix of progress and pressure—recent storms, saturated soils, and rapid weed growth are all shaping how this season is unfolding.

In this week’s Crop Talk, the agronomy team shares boots-on-the-ground insights on spray timing, weed control challenges, early crop stress, and what growers should be watching next.

In this episode, the team discusses:

• Post herbicide progress in corn and soybeans across regions
• Wet conditions, storm damage, and crop recovery (leaning, yellowing, compaction)
• Waterhemp and grass pressure increasing with delayed applications
• Spray considerations including gallons per acre, adjuvants, and coverage
• The “150 rule” and how heat + humidity impact herbicide performance
• Adjusting tank mixes and AMS rates based on conditions
• Early-season stress showing up from excess moisture and sidewall compaction
• Alfalfa insects and disease, including aphids and leaf spot management
• Early disease risk in corn following wind damage and leaf injury
• Fungicide planning and why preventative timing matters
• Planning ahead for resistance management and future herbicide programs

Conditions still vary field-by-field. Staying timely, adjusting to weather, and continuing to scout will be critical as we move deeper into the growing season.
