Midwest Farmers Advised to Scout for Pests Amid Wet Spring Conditions
US · Published May 15, 2026
Farmers across the Midwest are being urged to monitor their fields closely as warming temperatures and wet spring conditions have created favorable environments for pest activity.
According to entomologists, black cutworm moths have been migrating into the region, with feeding risks for corn expected through late May.
Similarly, alfalfa weevil larvae are actively feeding in parts of Indiana and Michigan, with peak activity linked to heat unit thresholds.

Why It's Important?

The presence of pests such as black cutworm, alfalfa weevil, and true armyworm could lead to significant crop damage if left unchecked. Cornfields with delayed planting or heavy weed pressure are particularly vulnerable to black cutworm feeding, while alfalfa fields in Indiana and Michigan are at risk of weevil damage. True armyworm outbreaks can develop rapidly, potentially affecting corn, wheat, and other small grains. Fusarium head blight in wheat could result in reduced grain quality and contamination with DON toxins. These risks highlight the importance of timely scouting and intervention to minimize yield losses.
