Fusilade II Herbicide is not labeled to be used in home lawns or on Kentucky Bluegrass and would not be recommended. Instead you can use a product called Q4 control of the crabgrass and other listed weeds. We do not currently carry any products that are labeled for quackgrass that are safe for use in cool season turf. We would recommend spot treating with something like Roundup and reseeding the areas
