Wireworms are an important pest of corn, other field crop seedlings, and vegetables and can cause significant damage if not controlled. This field trial was established to evaluate the efficacy of neonicotinoid seed treatments and in-furrow soil insecticides to protect seedling field corn under a heavy wireworm pressure scenario. The trial was conducted on a commercial production field in Perkins County near Madrid, NE (40.781993° N, −101.463666° W). The field was selected for its likelihood to have heavy wireworm pressure due to the following: 1) past farmer observations of crop damage when planted to field corn in 2012; 2) sandy …

The objective of this field trial was to evaluate the efficacy of a single application of foliar insecticides at preventing feeding damage by the western bean cutworm (WBC), an important pest of corn and dry beans. Direct feeding by WBC larvae on developing kernels in the ear can result in yield loss, whereas WBC infestation can also lead to secondary fungal infections. WBC has undergone a rapid range expansion into the eastern Corn Belt within the last 16 yr. This study was conducted within the historic range of WBC, at the University of Nebraska-Lincoln’s Henry J. Stumpf International Wheat Center …
