What is this grass in my clover?

I have this grass growing in my clover and can't seem to get rid of it.
Is it Orchard grass?
Any recommendations on how to kill it?

sedge.

sedge.

Yep, looks like yellow nutsedge to me. If you do a search at Keystone pest solutions for “sedge” a few products show up. Look for something with the same main ingredient as sedgehammer. May find something cheaper. I’ve used it on my lawn at home never on a plot. Did so so on the sedge in my grass. But I didn’t do the recommended follow up application.
