What are these and how do i get rid of them, they grow about 3 times faster then my grass and are alot lighter in color?

It looks like quackgrass from your picture of a few blades or could be a rough stalk bluegrass (poa trevialis) being larger patches of lighter color from your description. I've had the same issue in some areas of my lawn, and tenacity helped if you can get your hands on it. The other way is to pull it/ dig it out, unfortunately. I did this in some larger spots of my yard. Careful if you plant seed mixes from big box stores, many times sun/shade mix has the poa in it as it does well in shade.

Check out this link for some info I found on it and some pics to maybe match up what your yard looks like? https://extension.umd.edu/hgic/roughstalk-bluegrass

I'm pretty sure that's not quackgrass, and I don't think tenacity works on triv. Perhaps what you both have/had is/was poa annua? Dmur, can you post any other photos?

Not quack and not poa t.

It looks like a sedge. Maybe yellow nutsedge.

Does it have a triangular stem? If so, probably some type of sedge. If you hold it at its base and roll it between your finger and thumb the triangular stem will be very noticeable if it has one.

Nutsedge.

Sulfentrazone or halosulfuron (sedge hammer ). The easiest thing to find is propably the ortho brand sedge killer and it's already mixed. I've never seen halosulfuron already mixed as I think it has a short shelf life in water. Sulfentrazone works faster in my opinion.
