The delayed planting season makes it easier for pests like black cutworm to invade. Black cutworm, the most damaging cutworm species in corn, is a migratory pest that shows up in the spring with storms.
The threat of black cutworms is a possibility every year. These pests arrive yearly in April and May with spring storms after migrating from the South. Their damage can range from very little to severe cases of stand loss in cornfields. Midwest cornfields serve as a main hotspot for these insects.
Alfalfa crops face many insects throughout their growing season. Some of these insects are beneficial and control a variety of pest species throughout the season, while others have the ability to decrease forage tonnage and quality.
