Answer by  janeb (71)

Black-eyed Susan disease is a fungal disease that affects plants and their leaves. The fungus is called Septoria Rudbeckiae, and it usually starts as black, angular lesions that spread into bigger and bigger areas of the leaves. The best way to treat it is to remove the infected leaves at the end of the growing season.

This is a disease for plants and especially for leafs. A sort of black spots will appear on leafs. This is caused purely by the germs and fungal infection for the plant. These infections for the plants are highly possible in winter season. With the help of germicides we can protect the plants from this disease.


Answer by  dwammer (710)

Black eyed Susan disease is a fungal spore that infects the plant and causes unsightly black spots and low leave count. The plant will continue to grow but unless a fungicide is applied or the leaves are removed, the spores will continue to infect the plants. The leave spots are mostly cosmetic but they also hold the spores.
