Phytophthora Aerial Blight
Periwinkles that is infected by this disease have leaves that take on a grey color, the leaves also shriveled. Constant moisture or the rainy season encourage this disease. The use of mulches is believed to control aerial blight by acting as a barrier between soils which are infested and the plant itself.
