Each year, Extension faculty from across the US compile fungicide efficacy charts for foliar diseases of corn and soybean. These charts list the major foliar diseases of corn and soybean and the relative effectiveness of foliar fungicides for managing those diseases. Ratings are based on the latest data from field trials across the US. Use the carts to aid your selection of an effective fungicide program for your crop. Corn and soybean charts can be accessed online from the Crop Protection Network.
