    Pre-emerge this fall and again in the spring. Either fert and mow tall now, or stress it out by drying out, a good hot period and mow low once brown, will shrink but not get rid of. eitherway pre-emerge twice a year. a good cold winter will help to get rid of also

    The lawn is irrigated and won't dry out so maybe I'll try pre emergent in the fall.Thanks
