Has anybody ever seen orange spots on mallow plants? One of the mallow plants here seems to be under attack by this stuff. Anybody know of ways to prevent this? Foliar sprays? Companion plants? Any tips would be appreciated.

When I worked in a retail nursery in Seattle, WA we rarely carried ornamental Malva spp. because rust was so common. I am not aware of a solution. If you are in PNW (assumed by moniker), this has been a nasty spring for such vulnerabilities.
