How to control septoria leaf spot with rudbeckia

Hello

Last year my rudbeckia became severely infected with what I believe to be septoria leaf spot. By the end of the year, the leaves were almost completely black!! When I looked at them this year, they looked so bad that I just pulled them up. I'd like to plant some more, but I'm afraid that they'll just get sick again and die. Does anyone know how to prevent and/or control this evil disease??
