My peaches are rotting on the tree. I suspect they have Brown Rot. This crop is ruined but what can be done to prevent this in the next growing season?

Based on your description this sounds like brown rot. This is common on peaches and requires a spray schedule for control. http://extension.umd.edu/growit/diseases-stone-fruit
Many cycles of infection can occur in one growing season and ripening fruits are most vulnerable to infection. A protective fungicide barrier is critical from prebloom through preharvest. It is too late to spray this year.
At least, remove and dispose of fruit mummies from the ground and from trees and always try to remove fruit stems attached to the mummies, if a problem.
Next season thin the fruits on the tree. A portion of the fruit is removed so that the remainder will develop adequate size. Look at our website for more reasons for thinning the fruit. http://extension.umd.edu/growit/fruit-trees-fruit-thinning
Look at the spray schedule from Va Tech. You will have to spray next spring. http://extension.umd.edu/growit/home-fruit-preventative-spray-schedule-and-management-common-problem...
