Will Q4 Plus Turf Herbicide kill tall fescue grass mixed in my yard?

I have a Kentucky Bluegrass lawn and have tall fescue starting to invade. Will this kill the tall fescue and leave my bluegrass alone?


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.
