Leaf curl on peach tree

Question

My peach tree was full of blossoms and looking really good. All of a sudden it seems the whole tree is full of leaf curl. I had really warm weather and then it got very cold and wet again. I have the copper fungicide which suggests using in the fall or before blooms in the spring. Is there anything I can do now after the blooms have come and gone?

Answer 1

No, fungicides have no effect after the disease has taken hold.
