The present disclosure is drawn to a method of treating turfgrass for fungal disease. The method can include applying an anti-fungal composition to soil covering plant roots of the turfgrass infected by a fungal disease at an average coverage density of about 0.0035 pound to about 0.0125 pound per square foot, wherein the anti-fungal composition comprises from about 15 wt % to about 40 wt % nitrogen content, as well as phosphorus and potassium. The method also includes watering the turfgrass on a daily basis starting at a time from about 5:30 PM to about 12 AM (midnight) and completing watering prior to about 12:30 AM the next morning (total watering window of time about 7 hours), wherein watering includes applying an average of 1/12 inch to ⅜ inch water to the turfgrass.
