Keep a close eye on your lawn over the next few days and weeks.  Fungal diseases are rampant in turfgrasses right now and there is no sign that they will slow down anytime soon.  Disease pressure is through the roof right now with the high temperatures, humidity, extra moisture (irrigation) and soaring nightime temperatures of over 75 degrees.  All of these factors combine make for a "perfect storm" for disease development in turf.  Brown patch and summer patch is what we are seeing mostly, with occasional dollar spot.  Curative treatments of fungicide are recommended immediately to stop the spread of the disease.  Please call the office or your turf manager if you have concerns.
