Fungus ruins beautiful lawns. There are about 100 fungal diseases that can quickly turn a green and vibrant lawn into a brown, ugly patch. Symptoms include a coating of white powder, areas that appear burned, mold, or spider-web-like threads.

Identifying the fungus is tricky so take a sample of the problem soil to your local Cooperative Extension Service to get advice on the solution.

How to Treat Lawn Fungus:

  1. Calculate the width and length of the area that needs to be treated.
  2. Buy either granular or liquid fungicide.
  3. Apply on a dry, windless day.
  4. For granular, set rotary spreader to the recommended level and apply half the product while running the spreader in an up/down pattern and half in a right/left pattern for even coverage. Water lawn to help product soak in.
  5. For liquid, just attach to the hose and spray problem area.


Lawn fungus is often a result of overwatering and fertilizing.


Exercise caution around bodies of water because fungicide may be toxic to fish and other aquatic life. Avoid breathing the dust or getting the product in your eyes or on your hands.
