Lawn FungusLawn Fungus

on April 24, 2013 by TruGreen

Has your lawn ever been diagnosed as having a lawn fungus? Don’t be embarrassed. It can happen to anyone’s lawn. In fact, there might be a lawn fungus running rampant at this very moment and you don’t even know it—though chances are you’ll notice something’s wrong.

There are many types of lawn fungus that can pose a threat to your lawn. Cool or warm temperatures, over- or under-fertilization, unbalanced fertilization and certain watering habits all can contribute to the onset of a lawn fungus or lawn disease. There are a number of signs that a lawn fungus of some sort is affecting the health of your lawn.

common signs of many different lawn fungus diseases

  • Spots/patches
  • Bleached turf
  • Stunted growth
  • Shredded or shriveled grass blades
  • Lesions on leaf
  • Dark growth at the base of the plant

If in fact a lawn fungus is causing the damage, then correctly identifying the particular pathogen is the next step. The fungi that damage our lawns are parasitic and basically steal nutrients from grass plants, which causes the grass to decline, turn off-color or in some cases die. When a fungal spore encounters a host in the right environmental conditions, a disease is likely to develop.

common lawn fungus diseases

  • Pink Snow Mold – White to pink fungal growth that feels slimy, favored by abundant moisture.
  • Gray Snow Mold – White to gray fungal growth that may form large irregular patches, favored by abundant moisture or snow cover.
  • Yellow Patch – Circular patches of light tan to brown grass, favored by cool, wet conditions.
  • Leptosphaeria Patch – Circular yellow patches or tan to brown grass, favored by cool, wet weather.
  • Stripe Smut – Stunted grass with a lighter yellow to green color, favored by high moisture conditions.
  • Leaf Spot/Melting Out – Tiny, circular, dark spots or larger purplish spots, favored by cool air temperatures, moist conditions and improper mowing.
  • Red Thread/Pink Patch – Small, light pink to red patches, favored by cooler weather and moist conditions.
  • Dollar Spot – Circular patches with reddish-brown borders, favored by humidity.
  • Brown Patch – Circular, light brown patches, favored by moist conditions or areas that remain wet.
  • Fairy Ring – Circular patches of dark green, often enlarged into rings, favored by mild temperatures and moisture, and sometimes in dry, hot conditions.
  • Rust – Small, yellow flecks on leaves, sometimes enlarged to form rust-colored pustules, favored by moderately warm and humid conditions or stressed turf.

Now, before you head to the computer and Google “how to treat lawn fungus,” keep reading
