Lawn Fungus Identification Guide

Brown PatchLeaf SpotSlime Mold

After careful manicuring and fertilization of your lawn, the last thing you want to see are defects. When defects, like bare spots or yellowing, crop up, you may immediately think watering and fertilization is all you need. In some cases, though, youre dealing with a lawn disease caused by a fungal outbreak that requires more than just maintenance.

In our list of common fungi-caused lawn diseases, youll learn how the fungi appear and what to do to eliminate and prevent them. Youll also learn whether the condition is harmful to your turf or not.

How To Identify Fungus On Your Lawn

Brown patches on grass are just one sign that your lawn is dealing with a fungus problem. You may also notice stringy red threads, mushrooms, and other forms of fungus and fungal diseases.

Understanding common fungal threats can help you identify the issue in your lawn. Some of the most common types of fungus and fungal diseases include:

Red thread, lawn rust, fusarium, and other fungal diseases can create brown, orange, or reddish-orange patches in your turf. A brown patch may also be a sign of weak grass instead of a fungal infection.

Symptoms Of Fusarium Patch

Fusarium Patch causes irregular yellow to brown patches, up to 250mm, to form on your lawn. Patches may bleach as leaves wither and die. Left untreated, the centre of these patches can start to rot, and eventually collapse, creating wet, slimy areas on your lawn. Whitish mycelium may be seen within the patch, and the outside ring of the patch is typically darker than the centre.

Under the right conditions, Fusarium Patch can develop quickly. In a matter of days, large patches may appear on your turf and reduce grass coverage.

What Do Mushrooms Mean For My Garden

Although it may be frightening to notice a mushroom in your garden, it does not necessarily mean that anything bad is happening! Mushrooms typically symbolize a positive change in your yard. When you notice mushrooms growing in your lawn, this means that the soil underneath is full of nutrients in the form of decomposing matter. That may sound concerning, but decomposing matter can be anything, including plant roots, bugs, and animals.

When mushrooms grow in your container plants, they may widen your eyes. How did it get there? Most fungi already live in the soil you buy. Potting soil is filled with nutrients and plant food, and while outside is exposed to various Fungi. The mushrooms growing in your garden are likely Saprotrophic mushrooms. This specific type of mushroom refers to a fungus that eats the decomposing matter and releases nutrients back into the soil.

If you use organic matter as fertilizer, you will likely see mushrooms appear throughout your garden. For instance, many individuals use eggshells in their gardens, because they are filled with proteins that allow for their plants to grow larger. The only way for the proteins to aid the plant in growth is if the matter is decomposed and released into the soil, and mushrooms do exactly this. It is also common with organic matters like coffee grounds and banana peels.

Helping Prevent Resistance To Fungicides

When using fungicides for recurring lawn disease problems, you need to alternate fungicides. Lawn diseases can become resistant to fungicides with repeated use. It is not as simple as picking two different products or two different brands you will want to select at least two fungicides with different modes of action or active ingredients.

How To Treat And Prevent Fusarium Patch

To treat Fusarium Patch, you should apply a suitable fungicide at the first sign of infection. Depending on the level of damage, and the time of year, it may take some time for your lawn to fully recover. A full recovery is most likely in Autumn, so if the problem persists through Winter, additional fungicide applications may be required to prevent further spreading. If required, seek advice from your lawn care expert, and follow the instructions on the label.

To prevent Fusarium Patch, you should avoid fertilisers that are too high in nitrogen, such as urea. Applying potassium to your lawn may also aid in suppressing the disease.

Alkaline soils are also more susceptible to Fusarium, so test your soil pH, and try to maintain a pH of range of between 6.0 and 7.5 for optimum performance. Avoid using lime.

Poor drainage can also encourage this fungal disease to grow, so aim to reduce lawn thatch on a regular basis and aerate your lawn regularly or as needed.

Overhanging trees and shrubs may also encourage Fusarium Patch, so trimming branches regularly can encourage light and air circulation.

What Is A Fairy Ring

A fairy ring is a cluster of mushrooms growing in a circular pattern, forming a ring or arc shape. The ring is caused by a fungus in the center of the ring that spreads its mycelium filaments outwards in all directions. Mushrooms appear at the ends of the mycelium network, creating a circle of mushrooms.

Why Do Mushrooms Grow In My Yard

Where do mushrooms come from and how can you keep them from taking over your lawn or yard?

To answer that, we need to better understand just what makes a mushroom. When a mushroom pops up in your lawn, youre literally just seeing the tip of the iceberg. The rest of it lies below the surface of your soil.

There are various kinds of fungi, but the ones that produce mushrooms are known as macroscopic filamentous fungi.

The above-ground mushroom part is called the fruiting body because it produces the spores by which fungi spread. The underground part of the mushroom, which is both vegetation and roots, is called the mycelium. The mycelium is made of a network of fine, pale, wispy threads called hyphae that are small but visible to the eye.

This photo shows a good view of mycelium:

The mycelium sends its threads through the soil to locate water and organic matter like leaves, sticks, logs, feces, dead bugs/mammals, etc. The hyphae make contact with the target matter and secrete enzymes that break the matter down into tiny pieces that the hyphae can absorb and transport back into the mycelium at large. This whole digestive process is what causes decomposition in nature.

The mycelium and the hyphae prefer to live and work in certain conditions, usually those that are dark and damp. You may have noticed this if you ever picked up a pile of leaves and found a colony of white threads and fruiting mushrooms underneath.

Your lawn may just be a good environment for fungi if:

Cut Down Tree Branches

Fungus loves to grow in shady locations where the sunlight cant dry them out. If your lawn or yard has a dense tree canopy, prune back some of the branches to let some light and air in.

If your trees are large and mature, your best bet is to call in a local professional tree trimming service. But if your trees are smaller and you want to try pruning yourself, remember these guidelines:

• Always sanitize tools before making the first cut and in between trees.
• Cut close to the branch collar.
• Look for a natural branch outcropping to cut to. Never cut in the middle of a branch and leave a stub.
• Never strip out all the interior branchlets on a limbthis will make it end-heavy.

This video from Strider Trees does an outstanding job of showing how to use these guidelines for safely and effectively trimming your trees:

What Are Lawn Fungus And Disease

• Lawn fungus and disease are ailments to lawns caused by pathogens that take hold on grass and can range from cosmetic damage to your lawn to grass death.
• There are a large variety of different lawn diseases and fungi which can affect a lawn. Observe your lawn closely and view the symptoms to figure out what disease is present.

Manage Red Thread With Cultural Best Practices

Diseases, such as red thread, are often harbored and survive in thatch. Managing thatch layersthrough yearly aeration and, if necessary, fall dethatchingcould help better manage the severity of the disease. Remember, thatch is not dead grass on top of the soil. It sits below the soils surface. Using a soil probe is the best way to determine the severity of thatch.

Managing pH and nitrogen levels is also important. Requesting a soil test can determine whether the soil doesnt have the proper amount of nutrients, which could contribute to the severity of red thread or other diseases.

In terms of fertilizing, its important to keep in mind that over-fertilizing can contribute to the problem. Thats one of the reasons its important to apply slow-release fertilizer at only the recommended rate and at regular intervals throughout the season. Extra fertilizer between regularly scheduled applications wont cure red thread. What fertilizer can do is keep grass healthy and put it in a position to outgrow the disease as conditions become less favorable for fungal growth. It can take a couple of weeks from the time red thread stops being active for the turf to recover and turn a more uniform green.

Collecting grass clippings after each mow can also decrease the number of fungal threads that are reintroduced back into the turf. Watering correctly can also ensure youre not essentially feeding the fungus.

It can take two or more years of careful fertilizing to prevent red thread.

What Is Fusarium Patch

Fusarium Patch is a fungal disease that first appears as small, water-soaked patches on the lawn. These patches grow in size and change colour, eventually causing your lawns leaves to die off.

Fusarium can affect many different types of plants, including vegetables, fruits, and grains. The fungus typically enters the plant through wounds or lesions in the leaves or stem. Once inside the plant, the fungus begins to grow and reproduce, causing the plant to become infected.

Are Backyard Mushrooms Dangerous

There are many types of mushrooms, from the tasty and edible to the dangerous .

By and large, mushrooms on the lawn are not toxic to animals or humans. However, some varieties are poisonous, causing symptoms of gastrointestinal distress in some cases and even death in others.

Never eat a wild mushroom you cant confidently identify. This is the #1 rule of mushroom foragers, and homeowners should follow it too. Often, poisonous mushrooms look very similar to edible ones, so its crucial to always positively ID a mushroom before consumption.

If your mushrooms are growing in a high-traffic area, contact your local cooperative extension office with a description and photos to determine if it is a toxic type or not.

Young children and pets are in the greatest danger of harm from eating wild mushrooms, both due to their smaller body size and their tendency to put things in their mouths.

If you think your child or pet has ingested part of a mushroom, call your doctor or vet right away to seek advice. And if your child or pet becomes ill after eating a mushroom, immediately take them to the emergency room along with a sample of the mushroom.

How To Fight Lawn Disease

The hedges are trimmed. You’ve got a full tank of propane for the grill and plenty of fixin’s. The cooler is stocked. Your neighbors are due over in a few minutes. Then you see it. A mysterious brown patch on your lawn that was not there a couple of days ago. Your good mood evaporates quicker than dew in a drought.

The fact of the matter is that the harmful microorganisms that put a damper on your party didn’t just appear. They’re present in almost every yard. Dwelling in your soil and upon your lawn are a myriad of thread-like forms of life called fungi.

Fortunately, it takes more than the presence of pathogens to bring on infection in lawns. Also needed are a host – a grass susceptible to a particular pathogen – and environmental conditions that foster disease. These conditions vary by pathogen, but generally include warm weather and extended periods of moisture. Drought and high heat can encourage problems as well because they reduce the grass’s ability to fight infection.

Will Lawn Fungus Go Away On Its Own

Unfortunately, lawn fungus will not disappear if left untreated. The most effective way to manage yard fungus is to use a fungicide and practice good turf management. Fungicides are designed to inhibit energy production at the cellular level and to harm cell membranes, which eventually kills the fungi that is attacking your grass. As with any type of pesticide, homeowners should do their research to identify the type of fungicide needed to manage a particular type of lawn fungus and make sure solutions are applied carefully and according to manufacturer instructions. Make sure to avoid overusing fungicide to prevent additional damage to your grass. If you are unsure about how to correctly apply treatments, contact a trusted pest professional.

*FRAC is an abbreviation for Fungicide Resistance Action Committee. The FRAC code/resistance group system consists of numbers indicating classes or groups of fungicides based on mode of action, and letters that refer to broad classifications of fungicides . Due to the risk of fungicide resistance, turf managers should avoid excessive use of fungicides within the same FRAC code/resistance group and alternate products among different FRAC codes/resistance groups.

**Plant mobility classification refers to a fungicides ability to penetrate plant surfaces or remain on plant leaf or stem surfaces without penetration. Fungicides that penetrate plant surfaces and are translocated mostly upwards through plant xylem tissues are called acropetal penetrants . Fungicides that enter plant cuticles or move limited distances in internal plant spaces, but do not translocate through vascular tissues are called local penetrants. Contact fungicides do not penetrate plant surfaces and only inhibit fungal pathogens residing on leaf and stem surfaces.

***Follow label precautionary statements, restrictions, and directions regarding tolerant turfgrass species, rates, and timing of applications.
