Brown spot forever?

We have been plagued with some areas of brown spot in our yard for the last few years. We have treated it with a fungicide for several years, and it goes away, but it always seems to return in late summer, or fall. Maybe it just goes dormant?
Anyway, we hired a yard feeding/treatment company this year and when it popped up again recently we called them. They treated it, but the guy told us it was in the soil and you can't get rid of it? That doesn't seem right, what do you guys say? Thanks for your input!

Houston area? Suspect termites.
Next possibility would be "cotton root rot" a fungus that lives in the soil. I have it at my homestead and cannot grow apples or cherries because of it.

The maintenance company is correct. Brown spot is naturally occurring in the soil. It can be controlled but not eradicated. If you've not been treating it generally takes heavier treatments to bring it under control. Then you apply low level prophylactic treatments every month to control it.

Tender, fast growing grass is very susceptible to brown spot and moisture exacerbates the problem. Only fertilize in early spring and fall and do not try to force the grass to be lush and green during the heat of summer. Many people fertilize to make it grow and think that watering can keep it lush during July and August but it creates prime conditions for Brown Spot.

Treat those spots for a week with a daily application of urine followed by an equal amount of water or dilute with water when applied.

Any supporting evidence for the urine treatment?

We're talking about written, factual evidence. Pics themselves are not proof.

Urine can help or hurt grass. I think it depends on either the type of soil or maybe the source. I've seen it both encourage grass growth and pretty much kill it. I'd go with the maintenance companies recommendation - after all, that's what they do for a living!
