Q4 Plus Turf Herbicide can safely be applied to established Tall Fescue to treat for listed weeds when applied during the cooler times of the days when temps are below 80 degrees. It is not going to kill Tall Fescue if used as directed. If you are wanting to kill Tall Fescue in your lawn, please provide your desired turf species for additional information. Thank you.
