Several applications of using what? I Use sulfentrazone at the 4 ounce per acre rate. You may need to do a couple of applications 2 to 3 weeks apart. You’ll need to treat for it every year once it starts to come up. After a couple years you’ll reduce it to the point where you may only need the spot spray. I’ve had real good luck using the above product. Sedge hammer will control it to, but that could get expensive depending on how much square footage you are treating

What are you useing? Location? Timing?
Zone 7 NY, Spring and late summer. sulfentrazone and tried Halosulfuron . Its seeding everywhere. It browns out after the late summer application but it comes back in spring. You dont see it in March but all of a sudden your walking of tufts of sedge. Also using the Herbacide Helper oil so it sticks. One acre property with vegetable garden and perenials everywhere.

Around here nutsedge seldom goes to seed--it spreads by the roots, rhizomes and nutlets--usually when soil is moved for some reason. For instance when perennials are transplanted into the yard from an infested nursery.
It needs temps of about 85 for a week or two before it appears above ground.
Halosulfuron is frequently applied in our state.
Sedgehammer is listed here as only "suppressing" Kylinga.

Is it this @joelcoqui ?
I think the op is dealing with false green kyllinga
It's moved north in recent years
