Looks like crabgrass to me. There are specific crabgrass killers, but I don’t have any experience with them as of yet.

Crabgrass – quinclorac is the herbicide you need

You got crabs 🦀. Crab grass. It’s deep rooted and an annual weed. Best bet wait closer to fall. Mow low overseed and keep seeding every week for about a month. You can also put a light layer of hay on top during winter. And repeat before spring really hits. Check local when to seed.

Kill it while you have a chance. Grass took over my whole back yard. I used torocity(knock off of tenacity) and it killed it over a couple weeks, with 1 spray a week.

Lol I just opened reddit to come ask if anyone else’s yard just got taken over in the last 10 days. Your post was the first to pop up. I just put down 2 gallons of spray and need to do more. It must be all this rain and heat. NW Illinois here.
Im ordering this right now for the problem in my other comment.

I really enjoy watching that take over my neighbor’s new lawn and then start invading my own lawn after I have fought countless battles and finally appeared victorious until the bozos next door to me moved in and didn’t even try to tend to their 1/2 acre lawn

I use quinclorac 75DF mixed at 1 Tablespoon per gallon, and add a little surfactant. It’s been working pretty well on the hairy crabgrass I’ve been fighting.
I spray the lawn where I see it coming up and then go back with the spray wand and soak spots like this. It’s usually dead in a week. There is always some you will need to go back and spot spray.

It’s crabgrass, you are providing a perfect environment to thrive by mowing as low as you do. Congratulations 🎉
