Is Q4 Plus Turf Herbicide effective on quack-grass in bluegrass lawn?

Answer:

Q4 is not labeled for quackgrass.  Quackgrass unfortunately is too closely related to Kentucky BlueGrass and most products that will kill quackgrass will also severly damage if not kill the KBG. The common recommendation is to kill the quackgrass with a glyphosate product and then reseed with KBG.
