Gray leaf spot (fungus) on St Augustine grass

Conroe, TX(Zone 9a)

I have identified my grass problem and read that I should spread corn meal or spray milk on the infected area. Does anyone have positive experience with either of these methods or have other organic suggestions?

Some sod was laid in early February after a landscaping project and that is where I first saw the gray leaf spot. Could it have been brought in or is it caused by my own overwatering only?

Thanks for your input.

I sprayed my lawn with milk last week and have mowed once. So far, the fungus has stopped spreading even after watering. And, thank goodness, the lawn did not smell like soured milk afterwards.
