Sulfosulfuron (Outrider) works better that the Halosulfuron. With the latter, the Nutsedge must be sprayed at a very young stage to get a decent kill. With the Outrider (as in pasture and fields) it seems to give a better kill.
Another trick to controlling nutsedge (as you will never get rid of it) is to use a good surfactant/adjuvant.
yep, good stuff.
but not labeled for corn...
My reply was in answer to the following by PCP:
Sorry to hijack the thread, but maybe Turfgrass can help me with this one - one of the fields I planted this corn in is my best chufa field. It has a good mix of volunteer chufa, yellow nutsedge and purple nutsedge. I'm planning to keep hitting it with gly all summer and try to at least knock the nutsedges back so that I can grow chufa again for a couple of years. I've got no illusions of wiping it out; just knocking it back some. Anything I could mix with the gly that would help? I could wait until the corn is made to use it. Thanks for any ideas.
The Outrider would get both the Johnsongrass AND nutsedge.
