continued Turf Talkproper rate has been applied. Theapplication rate for tall fescue is 3to 6 fluid ounces Fusilade II or 20to 24 fluid ounces Ornamec Over-The-Top per acre. For comparison,the use rate is about four times higherin broadleaf ornamentals — 16 to24 fluid ounces Fusilade II or 64 to96 fluid ounces of Ornamec Over-The Top per acre in nursery plants.So, expect greater control in orna-mental beds than in tall fescue dueto the difference in application rates.Dallisgrass, quackgrass andorchardgrass can also be suppressedin tall fescue through repeatedapplications of fluazifop. I havealso used fluazifop for control ofbrome (Bromus spp.) in tall fescue.Fluazifop, fenoxaprop or theircombination could be used forjohnsongrass management, or youcould make a wiper application ofa glyphosate product. Otherwise,you could spray a nonselective likeglyphosate and then reseed thetreated area for control of theseperennial grasses.Control inKentucky bluegrassBermudagrass can be suppressed/controlled in Kentucky bluegrassusing the triclopyr plus fenoxapropprogram discussed above. Onedifference is that the maximumapplication rate of fenoxaprop islower for Kentucky bluegrass thanfor tall fescue.Fluazifop cannot be used inKentucky bluegrass. Tenacity canbe used for nimblewill and creepingbentgrass control, as well as inbermudagrass-suppression efforts.Chlorsulfuron (Corsair) can beused for tall fescue control inKentucky bluegrass.I am not aware of a selective controlfor dallisgrass, orchardgrass orquackgrass in Kentucky bluegrass.There had been uses for sulfosulfuron(Certainty), but those uses areno longer on the Certainty label. Youcould use spot sprays of glyphosateand then reseed the treated areafor control of perennials.Control in zoysiagrassIn zoysiagrass, cool-season perennialgrasses like tall fescue or perennialryegrass can be controlled with applicationsof foramsulfuron (Revolver),sulfosulfuron (Certainty), trifloxysulfuron(Monument) or flazasulfuron(Katana). The Katana label also listscontrol of quackgrass.Another possible option forquackgrass, tall fescue and orchardgrasscontrol in zoysiagrass isthrough applications of pronamide(Kerb). Kerb is a restricted-useherbicide, however (it cannot beused in residential situations), andit has the potential to move downhillsides where it could injuresensitive grasses.Certain formulations of atrazineare labeled for dormant applicationsin zoysia, but its use is limited to theCoastal Plain of Virginia.
