Abstract:
In 2015, two separate experiments in Dallas, TX evaluated trifloxysulfuron-sodium (28 and 19 g ha-1) and foramsulfuron (29 g ha-1) applied singly in early or late November. Indaziflam (33 g ha-1), prodiamine (1120 g ha-1), and prodiamine + trifloxysulfuron-sodium (1120 + 19 g ha-1) were included for comparison. Treatments were evaluated in April 2016. Grid counts determined that trifloxysulfuron-sodium provided greater annual bluegrass control than foramsulfuron at both rates and timings. Late November applications of trifloxysulfuron-sodium at 28 g ha-1 provided ≥97% annual bluegrass control. All treatments containing trifloxysulfuron-sodium provided similar (≥90%) annual bluegrass control. Trifloxysulfuron-sodium application timing and rate did not affect annual bluegrass control in 2015 experiments.
