I've found maybe 5 blades of nutsedge in an area. Can I just paint them with roundup or is there an advantage to using a sedge-specific product? Of course if the problem were worse being able to spray it would be easier, but I'm wondering if I can just use roundup and a paintbrush and have it be just as effective.

I've used Sulfentrazone on my nutsedge and it worked really well. Took it out in about a week, IIRC.

The advantage of using a specific product would be you don't need to go through the trouble of painting it, just spray the area and walk away.

round up does not particularly work well on sedges. it would require almost undiluted concentrate to take it out, and possibly multiple applications at that.

Thanks @thegrassfactor that's the kind of answer I was looking for.

Coincidentally, I was just researching sulfentrazone vs halosulfuron for nutsedge control, and I came across your video on it. So double thanks!

There is an 4way brand (not Ortho wbg), that has sulfentrazone in it. You could get it a Home Depot/ Lowes in the concentrated bottles and it is inexpensive.

One application of concentrated RoundUp brushed on usually kills Nutsedge. Kyllinga is not very susceptible. Hate that weed more than Nutsedge.

If its only a small area I've just weeded it by hand and had no problems. Its easy to pull out and fairly rewarding. sprayed with a selective herbicide after to clean up any baby sedges I missed and never saw another one.

Gotta be careful hand pulling because of the nutlets/tubers. They can easily grow back if they're left in the ground. That said, I've had success hand pulling too (so far).

From what I've read this isn't reliable because the nut part of it can be a half foot or more underground.

I've had good luck using Sedgehammer Plus.

• 13.5 gram package Halosulfuron-methyl - 5%

• Each 13.5 g packet makes 1 gallon of finished solution and already contains a surfactant.

Roundup for Lawns also contains sulfentrazone, so it will knock out nutsedge.
