Tribute Total will work in Bermudagrass. I do not know how to control it in SA or zoysia. I encounter this weed more often than crabgrass in South Fl.
Post some picks.
Celsius applied in 1/2% MSO. Tribute is only labeled for Bermuda, however SA and zoysia will tolerate the AIs in it. Take note that one application of Tribute blows an application of Celsius, Revolver and Sedgehammer.
