Fungus in your lawn


When you hear the word "fungus," you know it's never good (unless we're talking about truffles, oyster, shitake or porcinis). Fungal diseases in your lawn aren't merely unsightly, they can be difficult to eradicate without the appropriate products and proper care. Our Fungicide Program treatments can help prevent the most common, unsightly fungal diseases that can damage your lawn.

Systemic fungicides

Fungicide products can be grouped into a category as protectant or systemic fungicides. Our lawn fungicides are systemic meaning the fungicides are absorbed by the plant cuticle and underlying tissues and can act by killing spores and hyphae. Because our fungicides are high quality, we only have to treat about every 30 days during the growing season.

Signs of fungus in your lawn

Lawn diseases each have their "seasons," but because of the heat and humidity, summer is prime time for many lawn diseases. Diseases begin to develop earlier than summer, but signs of disease and fungus usually start to show as the temperatures warm up. Here are some lawn characteristics that may be a sign of fungus:

  • Spots
  • Patches
  • Stunted growth
  • Small areas of dead grass

Common diseases our Fungicides can control

  1. Brown Patch: This is one of the most destructive diseases to Fescue. The damage of this soilborne disease first appears as circular areas of brown and dead grass surrounded by a narrow, dark ring. Brown patch fungus can return year after year and will continue to germinate and infect healthy grass if not controlled.
  2. Zoysia Patch: This fungus is a soil-borne disease we see in the spring and fall. It begins as small circles of 6 inches across and can grow as large as twenty feet. The center of the ring is filled with brown, damaged grass while the circumference has a distinctive orange hue when active. Zoysia patch will not go away without proper fungicide treatments.
