I have a Florida Prince peach tree that I have been growing for about two years. The leaves routinely get small brown spots, and then the leaves turn a yellowish-brown and fall off. The tree will sprout new leaves in several weeks and the process will start again. I think the culprit is brown spot fungus but I am not sure (pictures are attached). I have been spraying the tree with Daconil, now on a weekly basis, but it does not cure the disease. Can someone confirm what is attacking my tree and recommend a treatment?
