 Is there a pre-emergent that kills or helps control Nut grass?
I went to the local Lesco and picked up Manage (by Mansanto)
The directions say to "add 2 teaspoons nonionic surfactant"
I have no idea what that is can someone help me out with that?

Don't know of any pre-emergent specifically for nutgrass. I guess a
pre-emergent for crabgrass would probably stop seeds from germinating,
but I've never heard of it being used. Nor does it seem necessary.
Manage will easily eliminate it when it's growing.

A surfactant is a molecule that is can bond to water on one end and
something oily on the other end. Think of soap. In the case of
herbicides, it helps the herbicide spread out and attach to waxy
leaves instead of sitting there in tiny balls or rolling off.

Not sure why they specify non-ionic, though I think that type may
perform better in hard water. You could buy a surfactant at Lesco,
but considering problems like it's probably in a lifetime size qty for
home use, f it were me, I'd use a little bit of liquid dishwashing
soap and it should work fine.

Cyperus esculentus is *not* a grass.

You would probably have better luck with Sedgehammer (also from Lesco). If
they're still selling Manage, my guess would be it's old product.
Sedgehammer is the replacement for Manage. Gowan bought the rights to the
name Manage, last year IIRC.

You don't say what type of nutsedge you're trying to control. If it's yellow
nutsedge, controlling it is about all that can be done until it runs out of
energy and stops sending up shoots. Purple nutsedge, on the other hand,
might have some method of killing it, from what I've seen in some obscure
article on the internet; but don't hold your breath. Spray the shoots with
anything that will kill the shoots, but don't expect to kill the seed-nut
because it will continue sending out shoots until it depletes its energy
source. Of course, you can alway try to dig it out, but it no guarantee that
you'll find the nut. Just keep spraying, and pull out the occasional lone
shoot. The nuts are edible, in case you wish to gather a fistful and clean
them and roast them. Just about the time you begin to enjoy them, they'll
probably die off!

By the way, nutsedges are allelopathic (like walnut trees) and secrete a
chemical that discourages growth of other plants in order to assure its own
survival. Definitely a good idea to get rid of it if you can.
