The effect of foliar fungicides applied on foliar disease, stalk rot and yield of corn were evaluated during the 2011 growing season at six locations in Iowa: ISU Northwest Research and Demonstration Farm near Sutherland; ISU Northern Research and Demonstration Farm, Kanawha; ISU Northeast Research and Demonstration Farm, Nashua, Ames (central); ISU Southeast Research and Demonstration Farm near Crawfordsville; and the Armstrong Research and Demonstration Farm near Lewis (Fig. 1). Foliar fungicides were applied at various growth stages on corn (Table 1).
