Answer: Peach leaf curl is a fungal disease that attacks the leaves as they are unfurling. The fungus first causes reddening and cupping of the leaves. The second stage is the development of a dusty white coating of spores. If these spores travel to the fruit, the fruit may show a reddish growth on the surface. The fruit is safe to eat, even if the surface is infected. If possible, pick the leaves off prior to the development of the spores so the fruit won't become infected. You won't want to completely denude your tree - it takes 40 healthy leaves for each developing fruit to provide the tree with the energy to ripen the fruit and maintain overall health. Discard all leaves and fallen fruit at the end of the season. I think it's time for you to change the fungicide you're using; some strains can become immune. Try another brand of fungicide (or use a simple 29% lime-sulfur spray) and spray with the frequency the label suggests. Best wishes with your peach tree.
