LEAVES AND STEMS TURN GRAY ON RUDBECKIA

Fayetteville, NC(Zone 7b)

MY RUDBECKIA CAME UP THIS YEAR AND HAVE BEAUTIFUL FLOWERS ON THEM BUT NOW SOME OF THE LEAVES AND STEMS HAVE TURNED A GRAY COLOR. CAN ANYONE TELL ME WHAT THE PROBLEM COULD BE. I HATE TO LOOSE THE PLANTS.

Can you post some pictures? Might be something like powdery mildew but hard to say without seeing it.

will post picture tomorrow. i was told it was a fungus that rudbeckia get. one plant will be fine and the one next to it will turn gray looking and die away.
