Don’t let your lawn becomes entirely affected by these annoying causative agents because it is extremely difficult to treat them in such cases. Let’s try to find the best solution for your grass.

Lawn Fungus Types

Many fungus types can affect your lawn, but two of them are most common – a Brown patch (Large patch) and a Take-all patch (Take-all root rot). When fungi appear, they can damage large areas covered with grass in the south of the US.

This type of fungus can affect all kinds of grass, but it seems that it damages lawns with St. Augustine most common and most severe. Also, this fungus kills warm-season grasses such as Zoysia or Bermuda which grow in warm and humid climates.

The result is the occurrence of circle-shaped, browned patches on the blades of grass. It often affects large areas of the yard and, in extreme cases, it damages widespread parts across the lawn and leaves dirt behind.

In the very beginning, you may think it is about root rot since this fungus attacks the grass’ roots first. However, you will distinguish them after a while thanks to the changes on the leaves. In the States with hot and humid weather, you can face this horrible problem virtually year-round.

Unfortunately, you can be easily confused because the damage this fungus cause is often similar to some other causative agents. When you spot yellow, thin grass with dark, rot roots, you should immediately check if it is about this particular fungus. The sooner you diagnose the cause of the disease, the more chances you have to save grass in your yard.

Since these fungi prefer low temperatures, you can expect the problem with them in the period from fall to spring. Moreover, they live in decaying plant matter and the soil and usually spread through a root system. When you move infected grass or the ground itself to a new location, you will enable spreading fungi to the new areas.

How to Treat Lawn Fungus Disease

Identify Fungal Disease

When you suspect that your lawn is affected with fungi, look for thin and irregular-shaped yellow or brown patches on leaves. Your grass will look frayed and sparse, and the stains will become more significant over time.

Left untreated, the infection will spread and cause the death of your grass eventually. If you live in humid environments, you can notice grease spots and white, cotton-like fungi in some parts of your yard.

Prevent Lawn Fungal Diseases

You can help your lawn affected by fungal infections with the proper maintaining. Let’s see what we can do about this issue:

1. Choose the right grass type for your region

I know that an exotic lawn is unique and looks extraordinary, but you can save your yard from many problems by choosing a grass type which usually grows in your area and in climatic conditions that suit it most. Grass which traditionally grows in the particular region will be stronger and resistant to diseases which occur there.

2. Mow your lawn regularly

To prevent fungus infection in your yard, mow the lawn at a certain time interval by using a reliable riding lawn mower. That way, you will keep the height of grass as recommended for the specific species you grow.

Otherwise, too tall grass will reduce penetration of the light and air into the soil. Plus, irregular mowing won’t encourage adequate root development, and you can’t expect the appearance of strong grass resistant to the action of fungi.

3. Reduce shade

Too much shade in your yard will increase moist and decrease temperatures which are ideal conditions for the development of fungi. Regular trimming shrubs in your yard will make additional space and allow the sunshine to warm and dry the soil. That way, you will help to destroy the fungi and prevent their re-growth.

4. Change the way of watering

Yes, grass needs water for proper growth, but too much watering, consequently a high level of moisture in the soil, and continuously wet foliage will attract fungi. You can prevent spreading of diseases and help your lawn get rid of fungi by simple reducing watering.

Always allow the soil to dry out entirely between two watering and do that job early in the morning by using a hose timer. That will help the grass to dry out on the sun during the day.

5. Provide enough nitrogen for your lawn

If your lawn is nutrient-deficient, you can expect the development of fungi since they excellently thrive when the grass is weak, and the soil conditions are poor.

Adding about three pounds (1.35 kg) of lawn fertilizer rich in nitrogen for every 500 square feet (46.5 m2) of your lawn can correct the problem very quickly and successfully.

Treat Lawn Fungal Diseases

Keep in mind that fungal disease spreads quickly so that you can transfer fungi to healthy parts of the lawn by your footsteps, wheelbarrow, lawnmower, or your pet can do that while playing in the yard. It is always better to remove all grass clippings after mowing and use natural treatments to get rid of fungi.

a). Natural options

You should always find a way how to treat lawn fungus naturally. The best options are Neem oil, baking soda solutions, and compost tea which you can sprinkle or pour over the infected area. To get the best results, you should treat your yard with these natural options from the very beginning when the quantity of fungi is low.

b). Fungicide

If the disease spreads significantly and affects large areas of your lawn, you will probably need to apply a fungicide. Try to pick out the right one which is aimed at the destruction of the particular fungus species.

You can use one of two types of fungicide depending on the way of the application:

  • Contact fungicide is liquid. It coats the surface of leaves and destroys the spores.
  • Systemic fungicide comes in the form of granules. It dissolves into the ground and works on the grass root system.

Conclusion

Even though you will need to apply a fungicide in some severe cases, always keep in mind that using organic materials is still the best solution. Treating your lawn with such matter will help the grass in your yard to keep necessary balance and stay healthy and vigorous.
