Foliar Fungicide Study on Soybean

Results and Discussion All fungicide treatments reduced foliar disease symptoms (Table 1). Both Cercospora leaf blight and Septoria leaf blight (brown spot) were significantly controlled by the application of fungicides, regardless of timing or frequency. Yields were protected by the use of fungicides in this trial. All treatments exceeded the untreated control (UTC) (67.5 bu/ac) even though three treatments (Headline at R1, Headline at R3, and Quadris at R3) were not significantly different from the control. Plots treated with BAS703 02F had the highest yields.
