I have an attractive acanthus plant which unfortunately for the second year has had its leaves badly attacked by a white mildew of some kind

Is there any spray I can use to cure this? . We can cut off and destroy the worse affected leaves but wonder if the plant's longterm life is now doomed?

Dear Primrose, don’t think there are any sprays that the general public can buy these days, that actually work.
Maybe a good watering and mulch might help with the problem….
