What will kill nut grass and can be planted soon after?

Halosulfuron. You better read and make sure you can plant what youre wanting to behind it. It is residual. You could spray it with roundup, thatll kill it but the tubers will still be in the ground and itll come back when they sprout. Halosulfuron is the best thing but it just suppresses, it does not get rid of all of it. Sedgehammer, Profine and Sandea has halosulfuron in them. Nutgrass is a formitable advisary, i would recommend avoiding that fight if you can. I dont know that ive seen anybody beat it.

You don’t have many options. Products that contain halosulfuron or sulfosulfuron are the best to kill the nutsedge, but you will see injury or No germination in a food plot for this fall. You need a POST product only, and the choices are minimal.

Basagran, 1.5-2 pints per acre.

I’m going to try Basagran on some next year. When I put Nutsedge in the pest section on CDMS it brings up Imazapyr as well. If Basagran doesn’t knock it out I’m going to hit it with a Gly+Imazapyr cocktail and just accept I’ll have a bare spot for about a year.

You better read that basagran label. Lond term residual

I'm gonna live with it this year I guess. I sprayed cornerstone and burned the field up then came 3 acres of nutgrass.

I just went back and looked at the Winfield and BASF labels and saw nothing on plant back restrictions or residuals. There are grazing restrictions. It is labeled for the following crops : Alfalfa, clover, soybeans, corn, sorghum and has no effect on grasses. Maximum rate is 4 pints per acre per year. If you have information on residuals, please share it.

I have a couple of jugs of it. I was gona use it for nutgrass. I read the label and backed out. It was something about residual effect. Thats all i remember. My future intentions might have been different than what yours are. Its been about 8yrs.

.

I just read the label and i cant find anything thet resembles what i remember about reading it. I might be thinking of another chemical but i would have swore it was basagran. If you google "basagran residual effects" it says it has little or no residual effect. Maybe my memory is just slipping. I read alot of that kind of stuff

Basagran, or bentazon, will do fair on yellow, but not purple. Better than nothing, and like k bush said, no residual.

I sprayed my soybeans with Roundup + Basagran. One quart of each per acre. I sprayed the field twice, one week apart. I also sprayed the worst spots twice both times that I sprayed the field. The nut grass was much much taller than the maximum recommended spraying height, but even double spraying and spraying twice didn't kill the nut grass. It has made it bad sick, but it's not all dead. I'll do the same again next year, but I'll make sure I spray it when it's 6" tall.

And yes, I know that I sprayed double the annual, maximum amount, but that's just in spots in the field. Not the whole field.

Any major infestation, ryegrass, wild turnips, nut sedge, sickle pod will be a marathon not a sprint.

I have a couple of plots that have heavy infestations of rye grass, I think I have a lead on some Clearfield Wheat and if it works out I’ll spray with Imox. I’ll be limited to wheat:clover only for 2 years but hopefully I can beak the cycle.

Still have wild Turnips in some spots, I just get busy and let them get too big before spraying. Hopefully I’ll start breaking that cycle this year as well

Our worst nutgrass problems are on fields where we have planted chufas in the past. Not sure if there is a connection.

Nutsedge loves wet and thin areas.

Ours is sandy and well drained

I read where this stuff called “Yukon”” works well on it.

Yukon

The thickest spot in my soybean patch is on the side of a hill.

This is a solid 3 acres of well drained sandy soil. I sprayed it with cornerstone and that's when the nut grass took off.

That's the same thing I'm talking about. You even know the field!

My daddy pushed up a bunch of peach trees several years ago. I had never saw a blade of nutgrass in the orchard. I broke it up to plant watermelons the next year. I had a stand of nutgrass that looked like a football field, it was that thick. I have no idea where it come from. We farmed that field when i was growing up and it had peach trees on it for 25yrs
