i would love to see some tests done with
with the 3 available products(msma, sulfentrazone, sedgehammer)
for control of nutsedge

i would like to see 3 test plots loaded with NS
treated with one of each product for maybe 2-3 applications
and see which plots have regrowth of NS after a week, month , year

i have doubts that any of these products can really completely kill the underground
growth

any 1 know of any university studies done or likewise?

I don't know about any studies but Sedgehammer spot spraying has been great for me. I can spray it before or after mowing and the next week, it's yellow and dead.

I've had hit & miss with MSMA on sedge. Morethis year than i've ever seen. My best control is 2 apps 2weeks apart with 48oz/ acre MSMA & good surfactant. The only problem with this is that i don't like to to go back to re-treat just 1 or 2 yards.

I had good luck with Sedgehammer with silicone wetting agent last month--went back today--nutsedge was gone.

Tried using Momentum F/X this year as in a hadheld sprayer for Nutsedge.
Great results!... just have to make sure you spray both sides of the leaf, and use sticker.
Much cheaper than sedgehammer and yes it does kill it and quickly.

What are you using as a surfactant with the Sedgehammer? That stuff is awfully pricey. I wat to make sure it sticks.

Hawkeye from Lesco is good--but--costs $49 for a half gallon. So use a ordinary spreader sticker(any non-ionic surfactant). Or for small batches, dish detergent.

I'm surprised 2 pages and no one has brought up reading the label.

If Sedgehammer is Manage you are very limited to how much you can apply in a years time, as I recall you are only supposed to apply once every 6 weeks. No more than 4 applications per year.

Pretty much as I remember no more than 4 apps per season. Here is a link http://www.gowanco.com/Reference/Document.aspx?rid=312
