Powdery mildew

Saw some powdery mildew on a customer lawn in Binbrook

Then our office help said someone called about "Dust fungus." They had taken a sample into a nursery and the staff told them this was the name.

It does look like a white dust on the foliage and when you walk through it, a puff of white dust does float through the air.
