Good news!
Peach leaf curl disease is not going to bother your garden.
Here is our page on so-called 'stone' fruits (those that have pits) that includes peaches: 
https://extension.umd.edu/resource/growing-stone-fruits-home-garden/
The link within that page goes to an Ohio State peach leaf curl publication that states:
"Leaf curl is not difficult to control. Since the fungus survives the winter on the surface of twigs and buds, a single fungicide spray, thoroughly covering the entire tree", in either November or early spring before bud-break "will provide control."

Thanks for your fast reply Christine.  I’ll get the spray to be prepared to apply in November. 

You're welcome.
