Crop Talk by IAS – Field Scouting Update | May 26 

Crops are starting to respond as warmer temperatures return, and field activity is shifting quickly across Iowa. What we’re seeing in the field right now is a transition window—early growth is picking up, but weed pressure, uneven emergence, and timing decisions are becoming more important by the day. 

In this week’s episode, the team shares boots-on-the-ground insights on what growers should watch as post herbicide and sidedress season begins. 

In this episode, the team discusses: 

• Warm-up trends and how crops are responding after recent cool conditions 
• Increasing weed pressure and why timing matters for post applications 
• Targeting weeds before they exceed 3 inches for best control 
• Stand counts, emergence variability, and lingering crusting effects 
• Pre herbicide breakdown and what that means for current weed flushes 
• Scouting strategies—checking multiple areas across every field 
• Post application timing, tank mixes, and adjuvant considerations 
• Why mixing fertilizer with post herbicides can reduce effectiveness 
• Best conditions for Liberty applications and why “banker’s hours” matter 
• Crop response considerations with dicamba products in warmer weather 

The Crop Talk team emphasizes that conditions still matter field-by-field. As crops start to grow and weeds accelerate, timely scouting and properly timed applications will make the biggest difference heading into June.
