I have a peach tree in my backyard. It has quite a few peaches and they look pretty good overall, but a few had a spot on them and a jelly like substace came out. In Feb. I used Bayer Advanced insect control and poured all around base. The peaches were about one inch diameter when the brown spots started. Then in March I sprayed the tree with Bonide Fruit tree spray. Some of the leaves have a brown spot on them and they are turning yellow. I live in Northeast Arkansas. I don't know what to do.
