HI-YIELD Turflon Ester Ultra herbicide for the control of actively growing annual and perennial broadleaf weeds and kikuyugrass in perennial bluegrass, perennial ryegrass, or tall fescue. Marathon II lawns are commonly refered to as a dwarf tall fescue and because it is a specialty variety we are unsure of the effects of Turflon Ester Ultra on your turf variety. We would recommend performing a small spot treatment to test for sensitivity.
