What is the best product for peach leaf curl in Ohio?
We carry a couple of products that are labeled for peach curl, Docket DF containing Chlorothalonil and Bonide Copper Liquid Fungicide which contains Copper Octanoate (Copper Soap). We recommend you contact your local cooperative extension office and speak to the master gardener on staff to find out what has worked best for others in your region and also the best time to apply the fungicides.
