Spraying Sedgehammer/Grass Cutting
Posted on 10/27/20 at 11:21 am

Can I cut 24 hours after spraying Sedgehammer or should I wait longer?
I have always had a little nutsedge in my St. Aug but nothing like I have seen right now. Its even growing in large spots in my centipede (front yard) and I have never had it there.
Currently fighting nutsedge, webworms and brown patch in my St. Aug.

Label says wait 2 days after applying

Make sure you use a surfactant

At least 48 hours. If you don't like how Sedgehammer is working try Certainty.

This is a huge. Improved my effectiveness by 50%+

I mixed a little dawn soap with it

Wait 2 days to cut per label directions as already recommended, and Sedgehammer does have surfactant incorporated in the formulation - stated on the label in fine print. Doesn’t hurt to add additional though. Be patient takes a couple weeks + to start dying but it does cease to grow soon after spraying.

I have had success with it before. I'm trying to figure out what caused the nutsedge to take off like it has in the last 3 weeks. Does nutsedge spread by seed? I haven't seen any seed heads on any in my yard. Wondering if my neighbor dropped seed from his mower when he cut my grass.

Seed - I don’t think so, largely the underground tubers. In my yard usually July when it starts emerging. A couple sprays with Sedgehammer 3 or 4 weeks apart controls it for the year. Not sure why your emergence is so late - I’m not seeing any emergence at this time in my yard.

Nudgesedge spread underground through very fine roots and the “nuts”

Nutsedge will spread rapidly if it’s raining a lot. Also, a few plants go unnoticed for the most part so all of a sudden it seems like hundreds grew overnight

Why not mow then spray Op? How often you mowing these days? I’ve only mowed once in the last 3 weeks or so

I can make them out better if I spray before I mow. Mowing about every other week, but was out of town for 2 weeks and noticed it all when I arrived home. I kind of wanted to cut before the storm comes through but it's really not long enough to bother me or rush it. Ill cut Friday or Saturday.

I think Sedgehammer+ has the surfactant in the formulation but Sedgehammer needs a good nonionic at 0.25% v/v Added for max activity.

Nutsedge has a wide emergence window, especially the purple and yellow. Best time to apply the halo (Sedgehammer) is tween Sept 15 and Oct 15. As with any other perennial the source to sink in the plant is shifting from top growth to survival with reserves being moved to storage parts, like tubers (nutlets). So an application at that time, much like with glyphosate on other perennial weeds, will result in being moved to storage organs for activity and much better long term control and reduced populations over time.

You are correct.
I always add surfactant in herbicide solutions whether the label calls for it or not - it’s to cheap and to effective, not to use.

Yep - they specifically state not to use surfactant with that herbicide - another good one for sedges I’ve not used.

So is it still good to apply now? I was planning to apply this weekend after this hurricane passes through.

Apply it after the hurricane.
