Disease or water stress?

[swami7774]

I’ve got several spots that have developed on my front lawn over the past 3 weeks or so. We’ve had very inconsistent rain this spring/summer but I augmented it with irrigation. Any guesses to what this is? TIA.

Its really hard to tell; it could be disease, it could be poa-a or triv dying off.

You probably need to take some closer pictures, but every summer I could never really tell what was turning brown. The KBG I wanted or the poa-a I was trying tonged rid of. Just be advised that poa-a will bounce back in the fall, the poa-a in my yard always seemed to make it through the summer.

POA is more indestructible than anything man can make.

Baloney - I have seen acres of Poa Pratensis die in no time at all.

And yet, even though I've been in either extreme or severe (whichever is worse) drought for the past two years and haven't been able to water, it's still hanging on in much of my lawn.

Small patches of K31 have survived.

There are big sections of my lawn where all poa and festuca (including native sheep fescue) have died, but poa pratensis is pretty hardy.
