Powdery mildew fungus on new sod

I laid sod in May in Calgary, Ab. Weather was cool and rainy during May to August. In August I noticed that the new sod was gray or silvery colored. I watered but it didn’t improve. This sod is in a shady area, east to south location, between the two houses and fence. I have pruned the large tree near this location. Do I need to do anything to get rid of this fungus? Will it kill the new sod? 16 ft x 5 ft Hope not.

Thanks,
Kaye.

This problem can happen if new sod is not watered frequently enough as it is getting established, or alternatively if it is watered too much and there is poor drainage. This article has a good explanation:

Alternatively, if there is a disease, you would most likely be able to wash or wipe off the grey discoloration. This article discusses some other possibilities:
