Our peach trees have brown rot! *sob*

The other day, I walked around the side of the house to check on our fruit trees, and was HORRIFIED at what I saw. Our biggest peach tree, heavy with almost-ripe fruit just a week ago, was now filled with rotting peaches, hanging on brown branches.

It made my stomach weak just looking at it (both from the yuckiness aspect, as well as the realization that we wouldn't be getting any homegrown peaches this year). I snapped a few pictures, then turned to Google to figure out what on earth went wrong.

I came across this page, and it became quite obvious that our peach trees were infected with brown rot, which is a fungus that affects stone fruit. Upon closer inspection, the 2 peach trees that are immediately adjacent to the biggest one are also infected. The ones further down the property seem to be okay, although we'll be keep a close eye on them. I really don't want to have to spray fungicides, but I'm not finding many other alternatives. I'm planning on spraying this fall after we harvest everything from the other trees and garden. Then by next spring, hopefully the chemicals will have been diluted and dispersed enough where there isn't a concentration right where we grow food.

Has anyone else dealt with brown rot? What did you do to prevent it from spreading/returning the following year?

Affected fruit:

A whole lot of mummies...

Golden peaches shine like a beacon of hope. These peaches are furthest away from the affected peach trees, so we're hoping they won't become infected before they are ready to pick (not too much longer now!).
