Brown Patches in St. Augustine Grass?

My back yard started forming brown patches recently and I can't figure out what is causing it. Some of the spots look like someone poured gas on them. The spots are very defined, dark brown, totally dead and dryer than a popcorn fart. Other areas are just slightly brown and/or the blades of grass are turning yellow. I dug up a few spots looking for grub worms but didn't find any. I then sprayed some fungus stuff on the yard from Lowes last month and it hasn't helped. Can anybody recommend a product that they have had positive results from? Please hurry because it's spreading to my front yard!

Continue to use the Fung Away that you buy from Lowes. You might try using the granules applied with a spreader. Water them in good.

You can also go to the feed store and buy some corn meal. It isn't the same thing that you buy at the grocery store and you need to get it from a feed store. Spread it liberally on the areas and water it in.

You more than likely have a fungus and you can spread it with your mower. You need to spray clorox on the bottom of your mower and the blade, or you will be spreading it to the rest of your yard.
