Can I spray for Peach leaf curl with fruit on tree?

Question

Can I spray my peach tree for peach leaf curl now that the fruit is on tree? Noticed leaf curl on my trees this past week. Has several peaches on them. I live in western Maryland.

Answer 1

Spraying for peach leaf curl must be done in the fall or in the spring before bud swell to prevent the onset of this disease. Once the fungus enters the leaf, the disease cannot be controlled, which means applying fungicide will not help at this juncture.
