a fungus amongus

I've lost most of my peaches the past two years to a powdery fungus.  This year, I went online and researched it.  Louis sprayed the tree three times during the various growth stages and though we still had quite a few peaches overtaken by the stuff, the tree was loaded with good fruit as well.
A little over a week ago, because the branches were so heavy they were bent nearly over, I picked the largest of the fruit and because it was just off ripe, we put it in a covered box in a cool place.  I cleaned up the bad fruit which must be disposed of.  A few days later, we looked in the box and the whole thing was taken with the gray fungus.  We disposed of that and on Sunday evening we picked as much as we could before it got too dark to see, washed the peaches in the new outdoor sink, and peeled, sliced and bagged them for the freezer. 
This morning, I went up and finished the picking, washing, peeling and slicing.  In all, I put up about a gallon of peaches in quart freezer bags.  If we hadn't lost the first bunch, we probably would have had 3 gallon or more.
This evening, I cleaned up the bad fruit again, bagged it and will send it to the landfill tomorrow. The only other choice is to burn it according to the sources I read on the internet.  We will trim the tree up now that the fruit is off and spray it and the ground around down with this soap stuff that is supposed to kill the rot.  Hopefully the tree will have new growth before fall so that next year it can have a good crop again. 
The sources seemed to agree that the stuff can be eradicated in two years with diligence.  So next year we may have to do the same.  The fruit is good, even if somewhat bird pecked, and will be worth the effort if we can kill the disease.
