Q4 Plus Turf Herbicide is a post-emergent herbicide, so it will only be effective on existing plants that are actively growing. You do not want to apply in the fall when fall is transitioning into winter when plants are not activelt growing because they will not be able to absorb the product. The best temperatures to apply in are between 55 degrees and 90 degrees. So now would be a great and safe time to apply.

Q4 Plus Turf Herbicide is labeled to be safely used on tall fescue and will not control it. There is not a selective product that would remove one cool season turf such as Tall Fescue from another like Kentucky Bluegrass. We suggest spot treating with a non-selective like GlyPhoSel Pro and then reseeding after 2 weeks.
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.
