Expert Response

This tree has peach leaf curl. Your earlier submission of a tree with severe damage is not going to recover. There is likely bacterial canker on the tree, and iw tree will need to be removed. Peach leaf curl by itself doesnt typically kill a tree. There could be an additional fungus or an issue with nutrients in the soil. A home soil test in the area of the peaches could identify if there are nutrient imbalances in the soil that are predisposing the trees to be weaker.

The only time to treat peach leaf curl preventatively with a fungicide is in the Spring just before bloom. In addition, you should remove infected leaves and not mulch them into the ground.


Since your site has a history of peach leaf curl, I would suggest 2 fungicide applications on a 7 - 10 day interval. The safest, effective fungicides available for backyard peach trees are copper soap (copper octanoate) or copper ammonium and are known as fixed copper fungicides. Apply either of these copper products with 1% horticultural oil to increase their fungicidal effectiveness. The synthetic fungicides chlorothalonil, ziram, carbamates and ferbam are also very effective. When using fungicides, be sure to read the label before use and apply according to instruction.
