Septoria leaf spot produces brown or black lesions on the leaf, powdery mildew looks like a white powder sprinkled on the leaves, and aster yellows produces witches brooms, doubled flowers, dwarfing and yellowing. All fungal diseases proliferate in wet conditions, so avoiding over-head watering and watering in the evening, keeping the plants thinned out so air can pass around the leaves, avoiding using nitrogen fertilizers to limit susceptible new growth and removing the infected leaves will help control the disease. Dusting sulfur is effective on powdery mildew, as is spraying the leaves individually with a strong stream of water to knock off the spores. Copper-based fungicides are effective on septoria can slow the spread of the disease and protect new growth from it. There is no chemical treatment for aster yellows.
