Peach tree Gumosis
I've got gumosis on a 5 year old Harvester peach tree.
After a fairly exhaustive search, I'm finding that there is no known, safe fungicide for this disease. Every search says to plant varieties that are resistant to this disease, but I can't find a listing of these so called resistant varieties. Does anybody have a list. I've even contacted the USDA, and they've been no help.
