Killing Nutsedge

[MikeC]

Been using a Monsanto product called "Manage" Herbicide for killing nutgrass in the yard and garden. (It only has a turfgrass usage label)
They just sold the rights to it and the new name is "Sedgehammer". It works very well and is really pricey. $75 per ounce. Treats one acre.

Just found another product that is the exact same chemical and the exact same concentration called "Sandea" for only $30 bucks per ounce. It has a vegetable production label.

Wouldn't we like to choke some of these chemical manufacturers for playing games with us? :mad:

But they hand out such nice hats, sweatshirts, ice scrappers, blah, blah blah it makes us forget how much we pay them every year. :)

Tha only down side to the nutsedge selective is they have such a delayed reaction. i usually mix it with a little quickpro or alcohol. gives immediate stress and makes the customer think it is doing something immediately!

I have found that a slow kill works much better than an immediate kill.

For instance; spraying "diquat" on grass or weeds will turn it completely brown overnight but it comes back within a few weeks.

Roundup, or the generics, give a slow kill (sometimes a week)but it will be dead for quite a while.

Have noticed this with several other herbicides.

The longer it takes to kill it, the more chemical that will be transferred to the roots, thus doing a longer lasting job on the plant. Make sense?

I completely understand your point except my customers like instant results. They could care less if I have to spray it once a week. Just so it looks like its getting done. At my own property I have a different approach.

I bought Sedgehammer last year and it was $98 for the small itty witty bottle. I spot sprayed the sedge last September and it killed a bunch of it, I just have so much more to kill.

Really daunting stuff!!

I will look for the $30 dollar equivalent, thanks for the tip!

Maverick is another brand that can be used. $350 for enough to do twenty acres.

Mike I think Bassagran will work also.

Maverick is for spraying Johnsongrass in Bermuda fields.

Basagran only works on "Yellow" nutsedge.

Sandea works good on all of it. Purple and Yellow.

The purple is really tough to rid..................

Take a look at "Outrider" It will work and kill Johnsonngrass too.

Glyphosate is a common weedkiller here in Australia. It works well but it seems to poison the earth making it sometimes difficult to grow plants after the weeds and grass are gone.I use hot water and vinegar which seems to do the trick.

Glyphosate doesn't kill nutsedge. Set it back a couple days or so but not kill it. It also shouldn't be affecting the ground as it is not a residual.

 

[Australian Cattleman]

The manufacturers say not but I don't believe them.

MikeC: I got my information from the Overton Experment station about Maverick. They stated that it was cleared for pastures and would kill nutsedge. It will also kill Johnson grass. I submitted a photo of the nutsedge and recieved the reply from Dr. Gearld Evers. Also do a search and you will find out that the Maverick is effective on the nutsedges. University of Mississippi has an article on it.

Interesting. There is no residual on Glyphosate, no contraindications for planting any type of crop or plant after using Glyphosate, and we've never had any problems with planting following usage of it.

The only two products that I feel have done any good for me are DUAL Magnum and CADRE.

Actually a study was done at a university(MO, I think) which showed it did have an effect on the soil. When used on soy beans it seems to effect the bacteria in the soil, giving fungus the upper hand. If there is any interest I will try to find the link.
