QuinKill Max Crabgrass and Weed Killer is not labeled to kill poa annua, or annual bluegrass. In fact, bluegrass is highly tolerant to quinclorac. QuinKill Max can be used for some broadleaf species, including clovers, dollarweed, and speedwell. For better control of broadleaf weeds, you will probably want to tank mix with another product with 2,4-D or Trimec, such as Fertilome Weed-Out Lawn Weed Killer with Trimec. Be sure to check the product label to be sure it is safe to use on your turf.
