I would take off all the affected leaves and destroy them. Then I would treat with a product made by Hi-Yield called "copper fungicide". The copper has activity against both fungi and bacteria. You may need to re-treat in 7-10 days. Then I would watch the new growth for symptoms of the disease and treat as necessary. In the fall, cut all of the old plant material off and destroy. The new growth next spring may need to be treated early in the season to prevent the disease from showing up. Good Luck.

the Peony flower
I picked a beautiful peony from the garden for the vase on the table.
Peony is the common name of the plant.
The Jade Peony was written in 1995.
Grandma kept the jade peony in a red envelop in her pocket.
If you are referring to the spots that kind of look like dew then these are resin crystals generally referred to as trichromes. Other things can cause white spots, if they look like a possible fungus that is on the leaf then it could be that too.
Peony Park was an amusement park in Omaha, Nebraska. It closed in 1994.
A red peony means live giving.
The motto of Peony Park is 'The Place to Party!!!'.
