I have been fighting green kyllinga in my 419 for years. Celsius label shows it will work against kyllinga but didn't even phase it. Added Quinchlorac to the mix and that only stressed the 419 and not the kyllinga. I then tried Sedgehammer which did very little. I did a Celsius/Sedgehammer mix to no avail. I recently saw some post where someone mentioned Dismiss really worked well on it so I gave it a shot. I was seriously to the point of going glypho on it and just plugging it back so I gave Dismiss a try as a last ditch effort. IT WORKED! Or at least it appears to be working very quickly. The green kyllinga is browning out and the 419 looks great underneath it. I wish I could give a shout out to whoever it was that mentioned Dismiss but I can't find the post.

The pictures really don't do it justice because I had to mow at the 24 hour mark because my yard is in rebound. I did a spot spray and missed some so I will have to do another app in a few weeks but I have never been so glad to watch a weed die. My smile muscles are getting worn out!
