This has been popping up in my zoysia this year. I think it's nutsedge but I wanted to get the opinion of the board experts before I treated it. Thanks for the help!

You are correct , nutsedge.

That Zoysia looks like a lazy teenager. Slow to wake up.

It always takes it's sweet time. It'll be pretty healthy by the end of May.
Thanks for the help. I have some Sedgehammer on the way.

I have MSM Turf will that knock out the Chamberbitter??

Dismiss is the only thing that kills the Nutsedge we have in Houston. Sedgehammer or anything else from HD/Lowes was completely ineffective. It's expensive, but a bottle will last a while.

It will. Celsius is better but a couple apps of msm will take care of it.

Certainty or sulfranzatone kills nutsedge

MSM will NOT kill chamberbitter. Atrazine or Celsius works.

I don’t know why you are yelling at me but msm will kill chamberbitter.

The infamous sedge, I use dismiss on mine it's a never ending battle with that shite, took me 3 yrs to control button weed, but this shite pisses me off.

I’m using the all-in-one chart that was posted a few weeks ago. The chart does not list MSM as a killer for chamberbitter. I’m just quoting the chart.

From Grok:
quote:
MSM Turf’s Fit: While MSM Turf may have some effect on chamberbitter as a broadleaf weed, its absence from recommended lists suggests it’s not the most effective. Celsius WG or a 2,4-D-based herbicide might offer better control, especially since chamberbitter’s rapid seed production requires quick, thorough action.
