Unfortunately, you will need to spray several times, according to the instructions on the fungicide. Make sure to follow all instructions carefully in order to gain the full benefits of the fungicide. Here is an article that will help you with fungicide use:

Along with fungicide use, you will need to stop the spread of spores by removing any and all dead and dying material. Any infected material will be a vector for spreading spores. Keep all fallen leaves raked up and disposed of, completely. Trim all infected growth and respray with a fungicide to help destroy some of the spore load.
