Primo Maxx® plant growth regulator should be tank mixed at labeled rates and timings for optimum fungicide performance. Subdue Maxx® fungicide may be applied when conditions are favorable for Pythium Blight disease. For protection against snow mold, fungicides should be applied prior to snow cover. For areas with historical anthracnose incidence, Medallion SC fungicide is recommended for additional control during summer applications. For greens applications, a water carrier volume of 2.0 gallons per 1,000 ft² is recommended. Use a flat fan nozzle that provides thorough plant coverage. If the target is Fairy ring, fungicide applications should be followed by at least 0.1” irrigation. For all other applications, irrigation ca n be delayed until the end of day. Acelepryn Xtra is labeled for the control of white grubs, billbugs, black turfgrass ataenius, cutworms, annual bluegrass weevil, ants, and other nuisance pests in turfgrass.
