Black Spot
The characteristic black spots on infected leaves are patches of fungus, not dead tissue. The organism attacks only roses; it survives on canes and fallen leaves, then spreads easily during misty, foggy, or rainy weather. Black spot is common in regions where summer weather is warm and humid.
