Fungus on lantana?
Is there a common fungus which infects lantana?
I have some very large bushy beautiful lantanas which about 2 months ago were blooming like crazy. In the past month I've noticed no flowers and figured it was a normal cycle, but the other day looked more closely and saw what looks like powdery mildew on the leaves.
My neighbor has powdery mildew on her turks' cap but mine are doing fine. It's my lantana that look like they have white powder.
Is this a common fungus for lantana? Could it be something else? Is there something I need to do to get rid of it before it kills my plants?
Oh, I'm in zone 8b I think (San Antonio, TX - SE side)
