Fungal (?) on maples

[AaronS]

Hi everyone

My maples are suffering in the damp cool conditions we are having on the tablelands this summer. Leaves are being hit by what appears to be a fungal pathogen. Will try to get some photos later when the rain stops. Anyone else having this issue? If so, what are they doing about it?

Thanks
Aaron

In Melbourne I had my japanese maples in an area that got morning sun and afternoon shade. They ended up with powdery mildew on the leaves (I think that is what it was). The ones I had in sunnier airy places didn't have the problem. A bit of dilute lime sulfer seemed to do the trick. Melbourne has been quite wet this year as also.
