8 Natural Ways to Get Rid of Fusarium Patch Disease

Ever notice those strange, orange-brown patches of dead grass on your lawn in autumn and winter? Chances are you’ve got Fusarium patch disease.

Don’t worry, you’re not alone. This pesky fungal infection attacks lawns all over, leaving behind unsightly dead spots.

The good news is, with some simple natural treatments, you can eliminate Fusarium patches and boost your lawn’s health.


Fusarium patch disease, also known as pink snow mold, is caused by the fungus Microdochium nivale [1]. This fungus attacks grass blades, causing them to turn yellow or reddish-brown in color.

As the disease progresses, you’ll notice roughly circular patches of discolored grass in your lawn that range from an inch up to 6 inches in diameter.

Affected leaves may look water-soaked as well. This disease usually shows up in the late fall or early winter when the weather is cool and damp.

How to Get Rid of Fusarium Patch Disease Naturally

With some simple cultural practices and natural treatments, you can get your lawn back to health and keep the Fusarium patch at bay.

1. Avoid Fertilizers that are Too High in Nitrogen

Avoid using fertilizers that are high in nitrogen. Too much nitrogen will encourage lush, green growth that is more susceptible to disease.

Instead, use a fertilizer with more potassium during the growing season. You can also use organic fertilizers like compost tea, which helps protect your lawn from diseases.

2. Trim Overhead Tree Branches Regularly

One of the simplest ways to help prevent Fusarium patch disease is to regularly trim any overhead tree branches. Trees that shade your lawn, especially during the early morning hours when dew is present, create damp conditions in which fungi thrive.

By trimming back overhanging branches, you’ll allow better air circulation and sunlight exposure to your lawn.

More sun and airflow mean faster drying of leaves and grass blades. This makes the environment less hospitable for the Fusarium fungus.

3. Carry Out Aeration and Scarifying of Lawn

Aerating your lawn by punching small holes in the soil allows for better movement of air, water, and nutrients to the roots.

Scarifying involves using a spring-tine rake, power rake, or dethatching machine to remove dead grass, moss, and debris from your lawn’s surface. This opens up the lawn canopy and allows water, air, and nutrients to reach the soil better.

Aerating and scarifying are simple, natural techniques to improve your lawn’s health and combat disease. When used together, they can have a dramatic impact on the vibrancy and resilience of your grass.

4. Baking Soda

Baking soda has helped many homeowners tackle fungal disease issues, including lawn diseases. Therefore, I’d recommend giving it a try as a DIY treatment for fusarium patch disease on your lawn.

To treat fusarium patch disease with baking soda, mix 4 tablespoons of baking soda with 1 gallon of water.

Apply this homemade Fusarium lawn treatment to your lawn, golf greens, and other areas. Spay it, especially where you see the distinctive yellow or brown patches.

Spray it on with a pump sprayer or sprinkling can, coating the grass blades thoroughly.

5. Avoid Walking on or Mowing the Lawn

Avoid walking on or mowing the lawn at all costs, if possible. This can spread the fungus to healthy areas of your landscape.

Mowing the lawn too short can also promote the spread of the fusarium patch fungus. Raise the blade on your mower to cut the grass a bit longer, around 2 to 3 inches.

Longer grass blades will shade the soil better and reduce moisture on the leaf surface, creating an environment less favorable for fungal diseases.

Additionally, when you mow the lawn, be sure to clean your mower and tools thoroughly. This to ensure you remove any grass clippings. Grass clippings left on the mower or tools can harbor the fungus and lead to re-infection the next time you mow.

6. Vinegar

Another product with antifungal properties that you can try is vinegar. Vinegar is great at killing fungi, including those that affect lawns.

To treat infected areas of your lawn, mix equal parts white vinegar and water. This makes a homemade Fusarium patch disease spray.

Next, spray the solution directly onto the patches of grass. The acid in vinegar can help eliminate the Fusarium fungus.

The downside is that vinegar can potentially damage your grass. So be sure to only use this home remedy on the affected patches of your turf grass.

7. Captain Jack’s Lawnweed Brew

Captain Jack’s Lawnweed Brew is an herbicide that works against moss and certain weeds. It also works against certain plant diseases. This includes snow mold, dollar spot, and rust.

It will not kill your lawn or grass, only weeds and the target disease(s). Just follow the directions carefully for the best effect.

8. ZeroTol HC

One of the most effective biological fungicides for eliminating fungus on lawn is ZeroTol HC. This broad-spectrum bactericide and fungicide contains hydrogen peroxide and another ingredient that helps control the fusarium patch.

Using a combination of cultural practices along with this organic product can help prevent this issue from returning.

This Fusarium patch disease treatment, used as both a preventative and curative treatment, is an excellent way to control this disease in an environmentally friendly manner.


So there you have it: some natural ways to tackle Fusarium patch disease in your lawn without having to resort to harsh chemicals. It may take some persistence to get your lawn back to full health using natural methods, but the rewards are well worth it.
