"Do not allow thatch levels to accumulate. Use resistant varieties of Kentucky bluegrass (Ascot, Classic, Dawn, Eclipse, Princeton, Trenton), perennial ryegrass (Lowgrow, Lynx, Navajo, Passport, Precision, Rivierra II, Shining Star, Target), and fine fescue (Biljart, Bighorn, Reliant, SR 3000, Waldina).
Where disease is severe, fungicide applications may be necessary. Although Red Thread is not often a problem on lawns, if it does become troublesome, homeowners in New York State may apply a registered fungicide to manage this disease. In spring or fall, apply Bonide Fung-onil MPF Conc. (chlorothalonil), Spectracide Immunox MPF (myclobutanil), Bayer Advanced Fungus Control for Lawns RTU Granules (triadimefon), or Heritage (azoxystrobin), or apply a registered fungicide containing the active ingredient propiconazole according to label directions."
I hope this helps you.
