Brown Patch Fungus Disease

Patchy grass

Areas affected by Brown Patch Fungus in Florida will be slow to green up in spring, but they will eventually because Brown Patch Fungus does not kill! Given adequate moisture and high humidity, along with temperatures in the 70’s and 80’s, more plant diseases will naturally go away (especially Brown Patch Fungus). This disease resurfaces in the fall, in exactly the same areas that were affected that were so slow to green up in spring. It’s important to keep in mind that fungicides cannot repair the damage done by a fungus - they can only prevent the spread of it under best circumstances.

Indicators of Brown Patch Fungus

Brown Patch Fungus is identified as a circular area in your lawn, usually 3-10 feet in diameter. On the edge of the area, you will see browning or yellowing grass, yet the interior of the circle may be a more healthy green. Pull blades of grass at the edge of the circle, and if the blades pull away easily from the stems, look brown, and are rotted at the base of the blades, this is a sure indication that you are dealing with Brown Patch Fungus in Florida.

How to Prevent the Disease

Another way to discourage Brown Patch Fungus is to eliminate watering in the evening. Water droplets that stay on the grass all night will spread the spores of the disease. Therefore, water in the early morning hours so that the grass will dry out during the day and before nightfall. To avoid spreading the fungus:

  • Do not walk through or let pets run through the infected areas when they are wet.
  • Do not mow the grass when it is wet! This will cause the rapid spread of spores.
  • Call Evergreen Lawn & Pest Control for a local lawn care professional in Florida to provide more information and assistance!
