Nutsedge-Now or Later (Not the candy!)

Is it worth killing the established nutsedge that I have in my yard now or just depend on my Pre-M apps to control it for next growing season.
Thanks!

What are the typical lows and highs where you live? Nutsedge grows slowly below 70--seldom a problem--until the temp exceeds 80 in the spring.

Many pre-emergents have no effect--be sure you use the correct product labeled for nutsedge. It arises from nutlets--not seed.

Since its so dry here right now with projected highs in the mid 70s-low 80s and lows in upper 50s-low 60s. It may be ok the wait on a treatment. I'm hoping cool weather will come and give me a break.

If its your lawn try hand pulling if its in a small area that will help to starve the tuber. Nutgrass is something I battle continuously.

nutsedge control

I treated some nutsedge Sept 3rd.
I used Manage (now named Sedgehammer). It was somewhat effective after 13 days--at least the lower leaves were brown. Growth was slow--but that could be due to cool weather. Top pic.

I also used Surge--it was effective--it worked nicely. Lower pic. Surge contains some sulfentrazone as an active ingredient.

The area had plenty of crabgrass also--now mostly brown.

Not sure what grass type but celsius applied in the fall has some excellent effects on underground tuber. Wild garlic/onion for instance, it will cease winterization and rot the stuff during the winter.

Fore,
Warm season for me. I dont do cool season.
This comes from my rep on muda and zoysia. The problem is cost associated.
I am becoming alarmed with our increasing problem locally of dallisgrass. Cant use msma and sencor. Sencor doesnt have res label and msm gone from the res label. The only thing left is a 150.00
Per acre treatment twice a year. See how well this factor figures into basic accounts. There is always gly and spot treats....... Landmine syndrome!

Man...that is around 3 times even a great mixture of 3-way plus Quicksilver - times 2 more if you have to hit it twice a year. Thanks for your response.

Pre-M will not control Nutsedge. Your best bet is to use either Pro Sedge, Sedgehammer (same active ingredient of Halosulfuron), or Dismiss (active ingredient of Sulfentrazone) on it next year as it begins to show up.
