I am not an applicator but I do know quite a bit about lawn care. Been cutting since I was 14 and am now 34. Anyway my wife and I bought this house 3 springs ago just before the grass started growing. Here we are into our 3rd spring and I am getting red thread creeping back into my lawn again already this year. This will make 3 years in a row I get taken over with red thread. My lawn is a hair over 2 acres. So far this year I have applied lebanon 19-0-6 slow release with dimension about a month ago. I am cutting twice a week at 3". In the summer I cut at 3.5" to 4" once a week once things start to slow down. I do not bag so the nutrients get recycled back into the lawn. I do not understand why I keep getting this and my 70 cutting customers hardly ever get it. Here is a pic from last year when it was really going wild. I do not want to let it get like this again. I need to nip this in the butt before it gets any worse. What products have you guys found works best on red thread and how often will I need to apply it. I have a 15 gallon tow behind boom sprayer that I use to do blanket apps for weed control that I can use to spray my lawn. I was thinking Eagle 20EW. Here is my local supplier. This is the list of fungicides they sell. Take a look and help me make a plan of attack to get this under control. http://newsomseed.com/fungicides.html Before anybody even says it..... I know in the picture the spots look brown. Before the areas turn brown the blades curl and turn red and I can see the red threads extending off the blades of grass. A friend of mine is the head guy in charge of a fairway lawns in arkansas and he doesnt deal with northern turf and doesnt get red thread down there but he keeps telling me to fertilize it heavy and let it grow out. My lawn already grows extremely fast and I really dont want to fertilize it more than I already do.
