    noticed this on a few of my lawns.i dont do any pest. apps. i subcontract that out but, im curious what this problem is.
    there are some of these brown spots on the lawn yet most of the lawn looks real good.

    Canadian geese dropings? can kill grass? Is those black and white feathers in the pic?

    If it is You need to ask your customer if they want it done and what I mean by this is having the lawn sprayed with flight control. It been a big problem this year. It not cheap but look it up it could be this.

    Poa annua is annual bluegrass. It looks OK in spring, then goes to seed, and usually craps out when the hot weather arrives. That may be it. I actually have a lawn I just looked at yesterday with the same problem. I wasn't completely sure, but I thought it was bentgrass that had died. It was a small area in a sunny area of the lawn. If anyone else has any ideas, I would love to hear them.

    Could also eb what's left of a fungus. How is the soil? The remaining grass doesn't look to good. Might be staved...

    You didn't use a Shade mix did you? Creeping Red Fescue can act like Poa and die out when the temps get up over 90-95 degrees. Or after a pound of nitrogen.
