Gray Leaf Mold

Dear Heirloom Garden:
      I am writing to you about grass in my back yard. We noticed that there are small dark gray spots on the leafs of my back yard grass. I spread some fungus away on them. Attached is the pictures, Would you please tell us what it is? How can we treat it? Thank you very much.


 Sincerely,

 Jennifer Dong


ANSWER:

This is called gray leaf mold.  It  is also known as sooty mold on grass.  The granular may not work as it is intended for root fungi.  I would suggest getting a product called Fertilome Systemic Fungicide,  it is a liquid and mixes in a hose end sprayer to immediately eradicate the pathogen.  We have it here at our store.  Thanks for the inquiry.
