    Basagran & Compass also works. Need to use spreader/sticker. Mix it strong. Spray it when it's as tall as possible with a fine mist (backpack sprayer or ride-on unit). Then wait 3 or 4 days before mowing or watering. We're seeing more of it this year than ever before. Personally, I'm wondering if a 100% kill is even possible, cuz nutsedge is very resilient and hardy. A banner year for it here.......4 to 6 inch rains, record-breaking rainfall, floods, etc. It's all over the place this year.

    I have been using Sedgehammer, but I decided to try some Dismiss this week. It works alot quicker but time will tell if it gets the nutlet or not. Persistance is the key.

    In case most yall haven't heard. There's a new, updated label for Dismiss. 0.18 oz/1000 on fescue. I got it mixed with Momentum FX2 at 1.5oz/1000. we'll see how well it works (or kills fescue :))

    I've heard late apps of sedgehammer don't work well. (haven't used it much)

    A golf course super' friend of mine said w/sedgehammer it comes back next year, but not w/ Dismiss.

    Even though you killed the existing nutsedge that does not mean new plants would not germinate and come through your sod. Your only option is to use a post -emergent like sedgehammer.

    If the nutsedge is coming back next year due to an application of sedgehammer this year, you missed plants or waited too late in the year to spray. No matter what you spray or how often you apply, you'll probably still have a least a little nutsedge the following year.

    I DESTROYED an area of nutsedge in a pretty big development with SEDGEHAMMER and a spreader sticker. took a few days longer than labeled, but i cant argue with the results.
