It’s a tough one. Dismiss or Sedgehammer can be effective with multiple applications. See Rutgers turf link above.
As much as I'd rather not, I'm leaning towards applying Sedgehammer this year as opposed to finishing up my supply of Dismiss. I'm thinking maybe I have both kyllinga and false kyllinga, and each product is more effective at one or the other. Regardless, I'll be spraying more chemicals, as much as I dislike doing so.
