Abstract

In 2024, the effect of commercial fungicides on foliar diseases of corn were evaluated at six Iowa State University Research and Demonstrations Farms: the Northwest Research and Demonstration Farm (NWRF, Sutherland), Northern Research and Demonstration Farm (NRF, Kanawha), Northeast Research and Demonstration Farm (NERF, Nashua), Central Iowa Research and Demonstration Farms, (AEA, Boone), Armstrong Memorial Research and Demonstration Farm (AMRF, Lewis), and Southeast Research and Demonstration Farm (SERF, Crawfordsville). All sites had a history of soybean in 2023. The hybrid planted was at the farm’s discretion. Plot size, planting, fungicide application, and harvest dates, are shown in Table 1. Depending on the location, fungicides were applied with a knapsack or ground rig sprayer.
