Corn earworm (or tomato fruitworm; Helicoverpa zea) is a migratory and ubiquitous pest infesting sweet corn ears, among other vegetable crops, throughout the United States. The key to successful management of corn earworm with insecticide applications is timing. The adult moths deposit eggs on the developing silk. Upon hatching, the larvae follow the silk into the developing ear where they are protected from foliar applications and wreak havoc on your produce. This video describes best management practices for corn earworm and resources provided by Purdue University to inform your management decisions. To access the corn earworm trapping network visit:
