Does My Lawn Have Fungus? Identify Lawn Fungus and How to Get Rid of Lawn Fungus with These Simple Steps

Before learning how to get rid of lawn fungus, you must first understand how to tell if your lawn has fungus in the first place. Fungus types typically vary depending on the location and humidity levels. For example, grass fungus in Florida differs from many other parts of the United States because of the consistently humid climate. This makes it easier for specific types of fungus in your yard to thrive, as most fungi require a warm, moist environment. There are four prevalent types of lawn fungus in Florida that can flourish if proper maintenance isn’t done to correct it.

If you live in a state with a very humid environment, such as Florida or Mississippi, grass fungus may have more potential to thrive. In humid climates, it is easier for the fungus in your yard to flourish, because most fungi require a warm, moist environment. There are four prevalent types of lawn fungus that can develop if proper maintenance isn’t done to correct it.

There are easy steps you can take to identify yard fungus and treat the most common types prevalent in your area.

What Does Lawn Fungus Look Like?

There are several ways to look for fungus in your yard. Brown, yellow and white patches or rings are the most obvious signs that your lawn is struggling against an invasive lawn fungus. While this could mean your grass is dying from lack of water and nutrients, a deeper look at your yard will help determine if it’s grass fungus or not.

Inspect individual blades of grass to see if you notice discolored, frayed, or distorted thin patches. Orange, purple, black, red, and gray spots or pink, gray, or black powdery coatings on or around each blade of grass are a sure sign that you have fungus in your yard.

Four Most Common Types and How to Get Rid of Lawn Fungus

  1. Brown Patch Fungus

This is the most common type of grass fungus noticed by homeowners, as large brown or yellow patches consume the lawn. We know this type of grass fungi as Rhizoctonia Fungus, which attacks the base of the leaf, causing it to die. New blades of grass might grow in the middle of fungi, creating the appearance of a brown or yellow ring as it develops and spreads further.

Fungicide is the easiest method when learning how to get rid of brown patch fungus. You can also apply our Bask recommended Bonide Concentrate Copper Fungicide to disinfect your lawn and prevent grass fungus from returning. This will vary in effectiveness depending on whether you have Centipede, Bermuda, Bahis, or St. Augustine grass, as well as how badly the current lawn fungus has spread.

2. Gray Leaf Spot Disease

This type of fungus in your yard will appear mostly if you have St. Augustine grass. This is a common lawn fungus in Florida, since St. Augustine grass is the most popular type of grass in the area.

Gray Leaf Spot Disease commonly spreads in Florida because of its love for warm, moist climates and its ability to create a thick carpet of grass. The Florida climate is also the preferred favorite of the Pyricularia Grisea Fungus, known to cause Gray Leaf Spot disease.

This yard fungus is unmistakable from any other type of fungi. It creates oval-shaped spots on blades of grass that can quickly spread and kill your entire lawn. This is especially true if your grass stays wet for an extended time because of excessive moisture or over-watering.

The only lawn care fungus treatment that works to stop Gray Leaf Spot Disease is a fungicide. Using this, alongside proper drainage methods, will kill this lawn fungus and prevent it from returning.

3. Fairy Ring Fungus

Unlike the previous two lawn fungi, Fairy Ring Fungus isn’t caused by just one type of fungi; there are over 50 different species of Basidiomycota that cause it. This grass fungus attacks your lawn from underneath, often in circular patterns. As it invades your lawn, you may notice patches of grass appear darker than others. Marasmius Oradea, a type of white mushroom, often accompanies it, confirming the fungus has invaded your lawn.

Yard fungus treatment for Fairy Ring includes a combination of dichlorophen, an antifungal agent, and core aeration. This fungus in your yard can be difficult to control, but with proper and steady maintenance, your lawn can return to its original state within a few weeks.

4. Dollar Spot Fungus

States with a year-round warm climate are more predisposed to the yard fungus Clarireedia jacksonii; this specific fungi thrives more in warm climates than in cooler climates in the US. Because of this, dollar spot disease is heavily prevalent in most types of grass, especially in bluegrass, zoysia, Bermuda, fescues, bentgrass, and ryegrass.

This grass fungus can often be mistaken for brown patch disease, as it has a similar brown or yellow circular appearance. However, the dollar spot gets its name from producing rather small patches, often beginning at around 1.5-2.5 inches in diameter, around the size of a US silver dollar. While it can grow over 5 inches, it is distinctive from brown patch disease, which causes significantly larger-sized patches.

Several yard fungus treatment options work to eliminate fungus on grass. If the problem has only recently started, applying nitrogen fertilizer helps your grass recover quicker and prevents the fungi from reappearing. If the lawn fungus persists, a fungicide will be the next course of action to treat it.
