Atticus Empero Nutsedge Killer (1.33 oz) Halosulfuron Herbicide Concentrate

This stuff actually works! I'm always a bit skeptical about lawn weed killers but I'm quite happy with this stuff. It is expensive, but you use just a tiny amount (one mini scoop per gallon). It knocked down most of my nutsedge within about a week. I apparently missed some so I had to spray again a couple months later, but it seems to be working really well. It turns the nutsedge yellow/brown within a couple days.

Works great, just have to be patient. It stunts the growth and plant slowly dies out.

Kills nutsedge, a little goes a long way.

Seems to work as advertised. It may take a few applications but the horsetail grass I sprayed is dying.

I have Nutsedge growing in my flower beds so I purchased Atticus Empero Nutsedge Killer based on internet reviews. It has the same ingredients as Sledgehammer but it's cheaper. It comes with a very small spoon that provides the correct amount to add to a 1-gallon sprayer. I used a 1/2 of spoonful along with a surfactant (so it will stick to the Nutsedge blades) into a hand spray bottle filled with water. I then sprayed the Nutsedge blades. It takes a couple of weeks for the Empero to kill the Nutsedge but it did a fantastic job of killing it all the way to the bulb (Nut) which prevents it from coming back. (Note: Do not mix more than you need because Atticus Nutsedge Killer has a 7-day life which weakens over time while sitting in a sprayer.) I highly recommend Atticus Empero Nutsedge Killer for killing Nutsedge.
