I noticed this (see links below) on My 7 Week old St. Aug Sod this morning. The new sod has been doing great so far. It has rained a lot the last week here. Sod get sun filtered through trees. I had put down cornmeal 2 weeks ago to help prevent fungus. Anyone know what this is? It feels like a marshmellow and comes right off if I pull on it. Some of the leaves are turning yellow and have spots. If this is a fungus what should I do? Thanks for your help.

It looks like mycelium. Not too much you can do for it. Check out this site on it: http://gardenline.usask.ca/yards/fairy.html IP: Logged |

Thanks for the info. Here is another picture from a different area of my lawn I just noticed tonight. It appears to be same thing at an early stage. <img src="http://i20.photobucket.com/albums/b215/robertsdarpic/St_Aug_night.jpg" alt="Image hosted by Photobucket.com"> IP: Logged |

I am pretty sure that is Mycelium. I think that site will tell you all you need to do. Hope it works for you. IP: Logged |

Thanks for the into. I don't think it is the dreaded "Fairy Ring" because there is no ring pattern. It may be Pythium blight (also called cottony Blight or Greasy Spot). After mowing, I now see this activity in 10 or 12 locations on new sod, but it seems to be going away (we have had no rain in last 3 days). I put more cornmeal down this morning. However, TROPICAL STORM Arlene is heading for us (Mobile, Alabama) and grass will likely stay wet for next 3 or 4 days. I'm worried that I should have used a fungicide, but don't want to kill off "good" fungus, so am holding off for now. IP: Logged |
