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.
