What product can I use to control azalea petal blight?
Try Yates Mancozeb Plus Garden Fungicide & Miticide. It is a multi-purpose, dual-active formulation combining the benefits of mancozeb and wettable sulfur. Both actives have a contact fungicidal action, helping to control and prevent the entry and spread of a range of common fungal diseases.
