Dead Grass / Weed Identification

I live in Northern NJ (Bergen County) and I have been battling issues with my lawn all year. I had/have several patches of missing/dead grass. I laid down 2 bags of Pennington Northeast seed (Pennington® : Northeast Mix) which filled most holes but it seems to be different than the existing grass. I also have quite a bit of dead grass which could be due to my dog but he is small and other neighbors with dogs don't have these patches. I always use the mulch feature on my mower so could it be the dead clippings? If so, I assume it would be everywhere and not in patches. A few weeks ago I noticed weeds sprouting up EVERYWHERE. I am not sure where they came from? I use Weed-B-Gone in various areas when I notice a weed or two but this came out of no where.

1) What grass do I have?
2) Why do I have dead patches?
3) What is that weed? Crab Grass? Why is it sprouting up now everywhere?

Looks like fescue to me and the weed is crabgrass. The turf could be perinnial rye also. My first impression was drought stress and isolated dry spots. Also might have noticed disease as well. What is the weather like and do you water regularly?

Fescue and perinnial rye, correct? I have a 4 zone sprinkler system that is scheduled daily for 15 minutes. We have had a lot of hot days during the summer but other lawns in my area look fantastic.

Daily for 15 minutes could be over watering and promoting disease. Try backing off to every other day schedule and just keep eye on soil moisture to adjust from there. It is also better to water early A.M. like 5 or 6 so that the plant leaf does not stay wet for prolonged periods. Most fungi thrive in warm humid environments!

Longer, deeper watering on a less frequent schedule will promote deeper roots. You need 1-2" per week and it's best if that happens in a couple of mornings, rather than daily.
