Clearys 3336F Fungicide is labeled for many diseases however without a positive id of the fungus, we are not able to confirm if this product would treat your cherry trees.
Please contact the Master Gardner Division with your County Extension Office for assitance in identifying the disease on your Cherry Laurels and for the best product recommendations and/or active ingredients to treat the disease in your area.
