Application Notice: Our State of Illinois Certified Applicators will apply T-zone or Speedzone to various turf grass areas (Athletic fields excluded) of Upper Campus, McCracken Field, and Freshman Campus the week of July 28th, 2025. Our time frame  is because of State of Illinois laws involving when we can apply lawn care products. Weather  and wind are a large factor. Look for “white flags” to know if an area has  been sprayed.
