Thank you for your question to eXtension.

There are several fungal diseases that could affect cherry, such as brown rot. These fungal diseases are most serious when we have long periods of rain in the spring, or lots of moisture and humidity during the period leading up to ripening.

The only way to protect your crop and get a decent harvest is to spray a fungicide several times during fruit development, usually at 7 to 10 day intervals. This Purdue publication gives specific information on what to use and when to use it, plus some non-chemical recommendations, for a wide variety of fruit crops: http://www.extension.purdue.edu/extmedia/ID/ID-146-W.pdf .

Please let me know if you have any other questions.
