There's a couple more pictures

 

Here is a better wide view pic to see bright green spots.

 

Can anybody help me out with above? Please

 

It's not jungle rice, it's poa trivialis. Looks very much like the triv I've been killing this year and last. Virginia Tech soil/plant lab positive identified mine as poa triv and said to use glyphosate to kill it. Spray at least two/three apps of glyphosate about a week apart for the foliage and roots to absorb the AI to kill the plant, do it during the spring when the plant is actively growing before it goes dormant during hot summer. If possible reseed or put down sod after final kill spray before summer is in full swing.

 

Thanks a lot for positive I'd. I was hoping otherwise but had a feeling that it was triv.

I'll second @Powhatan on this one: Poa Trivialis.

Rutgers published a blog post on this last year: https://turfblog.rutgers.edu/?p=1192

It's been rampant the last 2 years in Jersey with all of the rain we've gotten. Perfect conditions for it to explode.

 

@critterdude311 thaks for the link to that article. The pictures they show are identical to my yard. I spot sprayed with glyphosate two days ago. I see no other option than to suck it up a deal with collateral damage. I will attempt to put some seed down once it is dead but we'll see how that goes. Definitely going to focus on fall pre-emergent rather than over seed. I also have a lot of poa annua😞

 

And now my yard looks like this. It's sucks but sometimes you gotta take drastic measures.

 

My wife said, grass was looking so nice what happened with all of those brown spots? I told her that's where the squirrels pee. Naturally she didn't buy that one for a second. She knows how obsessive I am and how I'm always out in the yard doing something. LOL

 

LOL, do we have the same wife? I killed a bunch of spots, due to triv, and she was like "the yard looks like crap, what did you do now?"

 

You have to break some eggs to make an omelette.

 

I am in southeast PA and its exploded all a sudden in my yard too.

first saw it last year and there were a lot of posts on here about people seeing it too. Several members got it officially ID'd as triv after a lot of discussion of jungle rice, orchard grass, ect.

There is a long running thread here:

Didn't do anything last year to it, but will be getting out with round-up this weekend. i have a larger area so I think I'm going to get some PRG to put down to get something up quickly prior to summer and then most likely have my normal overseed in the early fall.

I have a large cluster right in the middle of the yard. It shows up pretty well in the pic below. I'm thinking of just hitting that whole area rather than selectively trying to get each plant and just be done with it. I then have smaller areas I can hit individually where smaller plants are growing.

Wife and the neighbors already think I'm nuts with the yard, this will only further convince them.
