Symptoms: This disease can occur on mango inflorescences, young leaves, young fruit and young stems. Generally, a powdery fungal growth can be seen on the affected parts. On young stems and leaves, small lesions in the early stage are surrounded by a brown ring; later the lesions merge into large white patches, which then gradually turn blue-purple.
