Large irregular yellow/dead one month old Saint Augustine

Hello, I planted sod a month ago. I have 11 large yellow spots where the grass is dying. It isn't just one area but is pretty much across the whole yard. The type of grass is Saint Augustine's Palmetto. The neighbor right next to me doesn't have this issue. The 3rd week it was planted it rained for a week straight. I was watering early morning and right before sunset. This is my first real sod yard. Do you have any idea what may be causing it? I am including pictures.

Where do you live? (always my first question because it usually is a factor in the solution)

The first picture didn't show me anything alarming. Second and third clearly show an advanced fungal disease process going on.

How long did the grass sit on the pallet before you put it down? The disease you have usually results from insufficient air movement over the grass. Did you leave a pile of leaves in that spot or maybe other garden clippings? It doesn't take much when left there for a few days.

The organic solution would be to apply ordinary whole ground corn meal at a rate of 20 pounds per 1,000 square feet over the entire lawn (because you don't know where it is and not showing up yet). Then reapply again in 3 weeks. You can get ordinary corn meal in 50-pound bags at a feed store. Call first. You do not want corn gluten meal. That has other uses. You want ordinary corn meal. It should be about $10 per bag.

The chemical solution I cannot help you with. In these warmer zones when you read the fungicide labels carefully, they are only good for temps below 75 degrees and no rain for the following week. One of the reasons I went to a full organic program was due to the success I had with corn meal on this fungal disease.
