Hi,

Dormant, delayed dormant, and postharvest treatments are effective timings for peach leaf curl.

Please refer to the Peach Pest Management Guide for available materials.

If this is backyard fruit you are limited to coppers or products containing the fungicide chlorothalonil.

Please see the leaf curl page in the PNW disease management guide for recommended materials specific for home use (marked H):
