Man I got infested or something but I mowed the lawn today to discover this all over my yard. I had it aerated 2 weeks ago and then overseeded with a light slow release fertilizer on it. Its pretty much all dead sod that breaks right up when I pull on it.
So whats the fix. I'd rather not dig it all up and was kind of hoping overseeding/watering would do the trick.

It's hard to say from a couple pics. Sorta looks like the remnants of a pink snow mold or something (but not active anymore). Seeding with good soil contact will bring up new grass. Maybe you went a little heavy with the fert?
How many pounds of Nitrogen per 1000ft2 did you put out? What are the temperatures day and night? |
| It was in the 80's for a bit last week but now is down to the 50's. I used Scotts "new lawn" or whatever you call it. Supposed to be used on newly seeded or sodded grasses. I know last year I had quite the weed problem. I'm wondering if the spray I used killed the whole area. |

It is likely a perennial weed grass that died last year. Run a thatching rake over it, and over seed. It may also be an area that died from disease last year. I would thatch it, put some fresh top soil on it, over seed and fertilize. Make sure you hit it with an insecticide fertilizer when the temps come up. (July)
The problem with the picture is it could be the result of so many things. The snow mold is another possibility. (We had it around here big time this year, and that is rare. The snowpack was heavy and lengthy this last winter.) Make sure the fertilizer you put down this year did not contain a pre-emergent for crabgrass. It also prevents grass seed from germinating. If you put down a pre-emergent, top soil is a must to have a chance at over seeding. |
