Organicide 3-In-1 Garden Spray Concentrate is not specifically labeled for leaf curl. Per the product label, "Diseases: Organocide Bee Safe 3-in-1 Garden Spray controls certain fungal diseases such as (but not limited to) Powdery Mildew, Downy Mildew, Black Spot on Roses, Helminthesporium and Greasy Spot on Citrus." For more information on this, you may contact the manufacturer (Organic Laboratories LLC) at 772-286-5581.
Another option would be Bonide Liquid Copper Fungicide Concentrate which is labeled for leaf curl. You may view the product label here.
