Listen in as Dr. Julie Peterson from the University of Nebraska Lincoln discusses western bean cutworm with host Ed Zaworski in this “I See Dead Plants” podcast.
Despite the name, “bean cutworm,” cutworms do not use soybeans as host plants. They lay eggs on corn and dry edible bean crops, and the larvae feast on new growth, such as corn tassels and then maturing corn kernels. In addition to the damage they cause, western bean cutworms spread disease between plants.
