Will Fusillade kill existing, actively growing quack grass in an IL cool season lawn

I do not want to damage the rest of the yard comprised of Kentucky blue grass and perennial ryegrass, will this selectively kill new and existing quack grass...typical growth between mowings reaches 3-5”. If not, what other product would suit My needs best when applying with 2 gallon spray jug and wand.


Fusilade II Herbicide is labeled for quackgrass (growth stage 6-10 inches), however, we do not currently carry any products that are labeled for quackgrass that are safe for use in cool season turf. We would recommend carefully spot treating with something like Roundup and reseeding the areas.
