QuinKill Max is not labeled to control Sisyrinchium. Atrazine is often used to control this plant in St. Augustine or Centipede turf. In other warm-season turf, you may have success with herbicides containing Trimec such as Fertilome Weed Free Zone. You can also always use a non-selective herbicide such as RoundUp QuikPro and just spot treat the areas where you find the blue-eyed grass.
