From the manufacturer

Are you tired of bothersome weeds overtaking your lawn?

Ortho Nutsedge Killer for Lawns Ready-To-Spray selectively controls tough weeds like purple and yellow nutsedge (nutgrass), kyllinga, wild onion and garlic, broadleaf plantain, purslane, redroot, pigweed, dandelion, spurge and other listed annual, biennial, and perennial broadleaf weeds. It can be applied on a great variety of Northern and Southern grass types. This no-mix, ready-to-spray formula will help kill pesky weeds, not your lawn.

When to Apply: For best results, apply to weeds when less than 3-inches high.

How Often to Apply: Apply when sedges are actively growing as needed throughout the season. Hard-to-kill weeds may require a repeat application if regrowth occurs.

Where Not to Use: Do not spray over the top of flowers, ornamentals (including herbaceous) or garden vegetables other than those listed on the label under 'Control of Weeds in Ornamentals'.

Do not use on turfgrasses other than those listed on the label.

For Spot Treatments in Your Lawn: Try the Ortho Nutsedge Killer for Lawns Ready-To-Use 24 oz. trigger sprayer.

Customers say

Customers like the performance of the weed moss control agent. For example, they say it works well and produces the best results when nutsedge is just starting to appear in the spring. That said, some complain that it turns the mosses yellow and causes some clover to brown. Opinions are mixed on quality and ease of use.

Customers are mixed about the ease of use of the weed moss control agent. Some mention that it's very easy to use, with an easy hose end attachment. However, others say that the hand spray is not nearly enough for the amount of nutsedge they have in their lawn, and that it takes several times applying. They also say that it works for nutgrass, but it takes a couple of weeks to work.

5.0 out of 5 stars It actually works!

Size: 32 Fl Oz (Pack of 1)Verified Purchase
My neighbor has an infestation of nutgrass and it's been invading my lawn for the last few years. In non-lawn areas, I've used Roundup on it but because of the root system it keeps returning. This stuff not only is killing the nutgrass, it also is killing the oxalis that invades this time of year. Bonus!

4.0 out of 5 stars It Really Works, But the Bottle Needs a Redesign
Reviewed in the United States on July 23, 2023
Size: 32 Fl Oz (Pack of 1)Verified Purchase
I've had nutsedge come up periodically in and around my lawn for the past three years or so. This product really does work (kills the nutsedge without harming the grass around it), but I've bought about 4 bottles in the past few years and this last one I bought from Amazon was defective and spewed the product out where the hose was joined (and all over me). Not good.

The bottle/applicator has always been a bit of a pain to screw onto the hose (meaning it works, but it can be a bit of a struggle or more of a struggle than it should be), but today's brand new bottle was just plain defective in some way. Even with the hose tight it was spewing water (and chemicals) out at the join and all around me/on me.

I'll buy it again, because it really does work, but Ortho should go back to the drawing board on the bottle/applicator.

5.0 out of 5 stars Gets rid of nut sedge quickly
Reviewed in the United States on April 28, 2024
Size: 32 Fl Oz (Pack of 1)Verified Purchase
Each year I had more of this light green patch of weeds called nut sedge. My regular weed killer didn’t touch it so I tried this nut sedge killer. It’s easy to use, covers the typical yard in a single bottle, and quickly kills nut sedge. It even rained later in the same Dayi applied it, but it don’t matter. Within a few days the nut sedge turned yellow and almost melted away. It will take a few weeks for the fescue grass choked out by this weed to reestablish, but at least it now has a good chance. Great product if you have this type of weed in your yard.

3.0 out of 5 stars Worked very well to eradicate Nimblewill, but...
Reviewed in the United States on March 2, 2024
Size: 32 Fl Oz (Pack of 1)Verified Purchase
It completely eliminated the Nimblewill from my TTTF lawn without harming the tall fescue. I had heard it damages TTTF but that must be only certain varieties, or maybe people used too much of it. I plan to try it out on Poa Annua this spring to see if it has any effect. I would have given it 5 stars instead of 3, but its a hassle that it only comes in a hose-end spray bottle, I'd much prefer to mix it myself and use it from a pump spray so there would be much less overspray and waste... but maybe they want you to use a lot of it.

1.0 out of 5 stars So why doesn't the sprayer work?
Reviewed in the United States on March 8, 2024
Size: 32 Fl Oz (Pack of 1)Verified Purchase
Simple task you would think. Hooked bottle up to my hose and started spraying per directions. Sound changed as I switched from WATER to ON, so product should have been dispensing. After several minutes of spraying with both high and low water pressure, no product was dispensed. The product contents line on the edge of the spray bottle never moved down and there was no characteristic change of smell as the sprayer went from WATER to ON. Looks like I've got an expensive and poorly designed hose nozzle instead of a weed killing machine. FYI, the bottle cap is designed to NOT be removable, so there should be no inner seal I forgot to remove, etc.
