Question on Kyllinga control with Halosulfuron-methyl

Posting this in warm season because I think it'll get more action...

Every Summer, I get a little bit of Kyllinga in a certain area. I think it's False Green. It's a really cool-looking plant. Anyway...
Finally decided to try spraying it last year to gain some control. Picked up a packet of Prosedge, and read the directions thoroughly before using.

Like a total amateur, I pulled off the flowers/seedheads first, because I didn't want the seeds spreading and landing in the soil. But the leaves come off with the flowers...LOL. So, there were only stalks left when I sprayed. Yeah, it's funny. I know.

Anyone know if the stalks actually absorb the herbicide? I didn't think about it until after I had sprayed.

Note, by seedheads/flowers, I mean when they were green and soon after they had first formed.

You mentioned a frost happened soon after you applied the Halosulfuron.
Where did you get that from?

Yes the stalks will absorb the halosulfuron. Did you use a surfactant or did the Prosedge have a surfactant included in it's formula? I don't use halosulfuron so I'm not certain on the formulation.
It either had it built-in, or I added or the other.
