I assume you mean that the peach fruit has brown rot. Young fruits are normally resistant, but may become infected through wounds. As fruits mature they become more susceptible to attack, even in the absence of wounds. Fruit infections appear as soft brown spots which rapidly expand and produce a tan powdery mass. The entire fruit rots rapidly, then dries and shrinks into a wrinkled “mummy.” Rotted fruit and mummies may remain on the tree or fall to the ground. Fruit infection may spread rapidly, especially if environmental conditions are favorable and fruits are touching one another. In brown rot on peach fruit, the fungus invades the twig causing a twig blight as well.

The most complete fact sheet I have seen on the prevention and control is from Ohio State at: https://ohioline.osu.edu/factsheet/plpath-fru-29
