Garden Tech Daconil Fungicide Concentrate is labeled for use on flowers, but does not specify a target disease for peony on the product label. You can contact the manufacturer directly with specific product questions at (941) 722-3285, or via their website's contact page here.
Additionally, you can reach out to the Master Gardener at your local extension office here for assistance in identifying and treating the disease impacting your peonies. We are happy to assist you in placing an order once you know exactly what you are dealing with and what product you need.
