Yes, you have to spray a fungicide (Funginex or Immunox), which prevents and protects the leaves from fungus. Start early in the spring as soon as your rose bush begins putting out leaves and continue every 7 to 10 days throughout the growing season. Alternate different fungicides so a resistance to one fungicide will not develop.
