Brown Patch – On Fescue (close up pictures)

brown patch on fescue

Q: In October we installed fescue sod over our entire yard. It remained absolutely beautiful until May. It seems that overnight it got big brown patches. After closer review under a magnifying glass it looks like the blades of grass are rotting right at the root.

A: The brown border around the tan spots on the leaf blades is a definitive sign for brown patch disease.

In my experience, overwatering and/or overfertilizing are the common causes of this disease.

You can prevent and control the disease with thiophanate – methyl (Infuse Lawn & Landscape Granules, Scotts Lawn Fungus Control, etc) or propiconazole (Bayer Fungus Control for Lawns).
