Q& A How do I get rid of this grey fungus in my lawn?

The most effective lawn disease treatments contain Myclobutanil, Azoxystrobin, Chlorantraniliprole, or Propiconazole.

Understanding Fungal Lawn Disease

When we talk about fungal disease in your lawn, we are talking about the overwhelming spread of certain fungi that will cause damage to your turf, which is known as lawn disease. Under certain conditions, the fungal spores in lawns will rapidly multiply and destroy everything green in their path. Wind, rain, excess debris, and generally unhealthy turf can all spread lawn disease. This damage is characterized by dead, thinning, and/or discolored patches of grass, and the following situations could lead to such problems in your yard:

  • Temperatures between 75 and 90 F
  • Hot days leading into cool nights
  • Having a susceptible grass species

Our List Of Lawn Diseases

The commonest lawn diseases are listed below.

Red thread

The red thread is one of the commonest fungal diseases on lawns, especially on lawns that are deficient in nitrogen. It produces brown patches, especially during a wet summer and during the autumn.

The red thread is caused by the fungus Laetisaria fuciformis. It rarely completely kills the grass and the patches recover with proper lawn preparation and treatment. Affected grass produces a reddish tinge, later becoming light brown or even bleached in appearance and the leaves may bind together. Patches vary in size, usually from 7.5cm to 25cm in diameter, but can be much larger.

Fusarium patch or snow mould

Fusarium patch, more commonly called snow mould, is a common cause of brown patches on lawns. It is particularly prevalent in autumn or during mild spells in winter, but attacks can occur at any time of the year.

Snow mould is caused by the fungus Monographella nivalis and at first produces small patches of yellowy, dying grass that usually turn brown later. The patches increase in size and may reach 30cm in diameter, sometimes merging so that large areas can be affected. During wet conditions a white or pinky, cotton-like fungal growth may be noticed, especially at the margins of the patch.


Fairy rings

Fairy rings are caused by a number of different fungi that produce rings of dead grass and usually toadstools in the lawn in late summer and autumn.

Common Types Of Lawn Fungus

  • Fairy Ring: This lawn fungus tends to leave ring formations of dark green and/or dead grass. In more extreme cases, you may even see patches of brown mushrooms. Fairy ring flourishes especially near dead vegetation such as tree stumps and thatch.
  • Rust: Light green to yellow to brown grass is the calling card of rust fungus. Heavy dew and excessively warm, moist weather helps spurn the growth of this fungus.
  • Pink Snow Mold: Identified by brown patches and yellow grass showing white or pink fungus spots after heavy rains. Heavy snow covers often associated with hills or banks can often lead to this fungus.
  • Slime Mold: White, yellow, or gray slime shows the presence of slime mold that clings to grass and occurs during prolonged wet periods. Slime mold also likes grass that has been left unmowed.

What Causes Lawn Fungus

Why Is My Grass Light Green?

Excessive heat and humidity are the leading causes of fungus. As mentioned above, fungus often occurs in times of stress, such as drought, long rainy seasons, and overwatering.


Fungus often develops because water stays on the leaf surface far too long. Mycelia use the water as a highway to travel from leaf-to-leaf. This allows the fungus to spread to other parts of the lawn.

This is also the reason that you should not walk through your lawn when it is battling fungus. If there is moisture on the lawn you can spread the fungus across the grass.

Another cause of fungus is undernourishment. When grass does not have the right amount of nutrients it is more susceptible to disease.

After it rains, theres typically more water available in the soil for the grass plants. When plants take up that water, they are also taking up nutrients thats in the soil. The more it rains, the faster that nitrogen is used up. If the nitrogen is not replenished, the problem will continue.

Will Lawn Rust Go Away On Its Own

Minimizing the shade your lawn gets can help kill lawn rust and prevent it from reappearing. Fungicides should only be applied to grass with lawn rust infestations in the most severe cases and before the disease goes dormant for the winter. Lawn rust may go away on its own if it is properly fertilized.

How Can I Get Rid Of Lawn Fungus Naturally

Following some cultural recommendations can definitely have an impact on the likelihood of a fungal outbreak as well as getting rid of lawn fungus faster. If you have an existing fungus problem, youll still need a lawn fungicide to control the spores but these additional practices will also help.For one, you should make sure that youre watering properly. The hot and humid weather of Northern Virginia can be like an incubator for fungal growth. But you can avoid contributing to excessive nighttime moisture by watering your lawn in the early morning and allowing evaporation ample time to do its work.Proper mowing can also make a big difference. Mow your lawn to a height of around 3 to 4 inches in the summer using a mower with sharp, clean blades. Lawns that are mowed too short are stressed and more likely to succumb to fungal infections. If youre aware that your lawn has diseased patches, be sure to wash and disinfect the underside of your mower after each use to prevent spread.

What Happens When Lawn Fungus Is Ignored

In the interest of the season, lets use the example of dollar spot a common lawn fungus that can appear anywhere between late spring and late fall in Ohio.

When these straw-colored patches of grass are treated like the rest of your lawn, the movement of mowers and foot traffic is bound to spread the disease. While a homeowner can reduce these types of movement, other environmental factors like strong winds or heavy rainfall have a similar effect.

As dollar spot spreads throughout a lawn, what was once a small patch of weak grass can turn into a damaged lawn that ultimately needs to be replaced. In terms of cost, lawn replacement can add up to $1.75 per square foot .

What Causes Anthracnose In The Lawn

First and foremost, anthracnose is caused by several different fungi that affect different species of plants, vegetables, and fruits. But in the lawn specifically, the main culprit is Colletotrichum cereale.

Beyond the fungus itself, treating your lawn has some sway over the manifestation and spread of anthracnose. All of these common lawn issues might contribute to conditions ripe for anthracnose:

  • Hot temperatures and moist weather conditions
  • Improper fertilization

How To Prevent Fungus

Water early in the day

Watering early in the day will allow your lawn to absorb the water and then dry off throughout the day. Watering late in the day or in the evening does not allow the lawn to dry and will promote fungus. Because fungus moves through water, a wet lawn will allow fungus to spread much faster.

Sharpen mower blades

It is always important to mow with sharp mower blades, but especially so when trying to prevent fungus. A dull blade can shred the grass blades leaving many openings for disease to enter.

Raise mowing height

When mowing, do not remove more than of the grass blade. This will allow the grass to stay healthy and strong. Scalping the lawn stresses the root system.

Dont over or under fertilize

Use high nitrogen fertilizer only in the spring. High nitrogen in late October/November will promote snow mold next year. When lawns have the right nutrients they need to grow, they are less susceptible to disease. Diseases such as red thread can often be controlled by adding nitrogen to your lawn.

Dethatch

Thatch is a layer of organic matter between the crown of the grass plants and the soil layer. Thatch can appear as a result of an imbalance in your soil or improper lawn maintenance practices.

We recommend removing thatch in the fall. Thatching brings up weed seeds and these are more prevalent in the spring. Use a heavy rake or thatching machine as needed to keep thatch to a minimum. The regular use of organics will help to keep thatch in order.

Eliminate As Much Shady Space As Possible

Although it can be nearly impossible to eliminate everything from your yard that can cause an obstruction to the sun, cutting large branches and trimming down bushes will help reduce the fungi buildup that is normally associated with shady spots.

Fungus thrives in moist, dark locations that typically dont see very much sunlight.

Lawn Fungus Treatment And Prevention

There are several things homeowners can do to help treat the fungus and to prevent lawn disease. You might consider taking some of the following steps:

  • If you have grass clippings, fall leaves or other debris sitting in your yard, make sure to remove them so that your yard isnt vulnerable to fungal growth. When you mow, bag your clippings so that you dont spread possibly diseased grass all over your yard.
  • Lawns with high nitrogen levels promote fungus growth, so test your lawns pH before adding fertilizer and add any amendments judiciously.
  • Water deep and infrequently in the mornings so that the grass and soil have time to dry.
  • Aerate your yard annually.
  • When mowing, dont take more than inch off at each time. Raise the mowing height to allow more surface area for your grass blades to take in sunlight.
  • Fungicides will help treat the diseased grass, while pesticides can help get rid of insects that are destroying your yard.
  • Avoid urea-based fungicides when treating take-all patch and take-all root rot.
  • If you have take-all root rot, lowering the pH levels in your yard can sometimes help.
  • Avoid walking through or mowing the diseased area when conditions are wet because there is a greater change you will accidentally spread the fungus to unaffected areas.

The best treatment for lawn diseases is a combination of turfgrass management and application of the right fungicide at the right times.

  • Use a fungicide to kill the fungus
  • Collect grass clippings when you mow
