Most fertilizer with 30-50% slow release nitrogen such as sulfur or polymer-coated urea, urea formaldehyde, or natural organics are use to combat this issue. But because it is slowly released, this fertilizer will be most effective if irrigated regularly If it is a problem in your yard as well, regular mowing will help break the disease cycle and help the turf outgrow the disease. If rust is a perennial problem on your turf, consider increasing the annual nitrogen applied. Good Luck!
