Symptoms and Signs[edit]
Initial infections are small, circular spots, usually with a differently colored zone on the outer edge. Severe cases cause distorted leaves or blight.

Host Range[edit]
Most of the pathogens are quite selective.
Controls[edit]

- Physical Removal: Clean up thoroughly in the autumn to reduce the amount of spores.
- Chemical Controls (synthetic): Neem Oil, Copper-based Sprays
