Spray the lawn fungicide. Choose a fungicide that treats the fungus that is infecting your lawn. There are two types of fungicides: the contact type and the endosorbent type. Contact fungicide comes in a liquid form. The drug coats the surface of the plant and kills the fungal spores that come into contact with the drug. This medicine usually wears off quickly and has limited effectiveness. The endophytic fungicide is usually granular and dissolves into the soil, from where it enters the root system. This treatment lasts longer. You should follow the instructions on the product packaging.

• Benomyl is very effective against many types of mold, including snow mold, brown patches and coin spots.
• Triadimefon works well against anthracnose and rust.
• Chlorothalonil is most effective for treating red and brown patches.
• There is no complete antifungal once it has entered the lawn, and antifungal remedies will only work against necrotic spots if you remove the litter from the lawn at the same time.

Try natural fungicidal methods. If you don't like chemicals, you can choose a natural fungicide. Neem oil, tea feces, and baking soda solutions all kill fungus. You can either pour or spray natural remedies over the affected area.

• Natural remedies work best when mold grows or is only in small numbers.
• Keep people and pets away from the treated area for a few days.

Note that some fungal infections are seasonal. Some fungal infections are caused by weather factors. Snow gray mushrooms will usually die when the temperature rises above 4 degrees Celsius. Rapidly warming weather can kill the fungus immediately. Likewise, some types of mycelium will disappear when the sun heats up and leaves your lawn dry. Other fungi, such as powdery mildew mold, will thrive in dry weather with high humidity.

• Fungal infections can go away on their own if you properly maintain your lawn.

Method 3 of 3: Prevent mold on grass

1. 

   
   
   Only water the grass when necessary. Most lawns only need 2.5 cm of water per week, but homeowners often water more than necessary. Many fungi thrive in humid conditions, so over watering will cause the fungus to multiply.
   • However, you shouldn't let the lawn get too dry. Dry soil will weaken the grass and become susceptible to disease.
   • It is best to water the grass in the morning, as the soil will absorb the required amount of water and the excess water will evaporate for the rest of the day.
   • If you are using a sprinkler to water your lawn, check it to make sure it is working properly. You should calculate how much water is watered on the lawn to adjust accordingly.

2. 

   Use a slow-release fertilizer with a low nitrogen content. Fungal infections can occur when you apply too little or too much fertilizer. To maintain balance, choose an organic slow-release fertilizer with potassium and nitrogen. The fertilizer will help keep the grass lush, which in turn can fight fungal infections.
   • Avoid applying too much nitrogen, as this can lead to overgrown and weak growth, leading to more susceptibility to infection.
   • Always follow the instructions on the product packaging to avoid misuse.

3. 

   
   
   Remove leaves from your yard in winter. Gray snow mold can grow under fallen leaves on your lawn. To prevent mold from growing, you need to scratch and remove the leaves before it snows.

4. 

   Set the lawn mower to the highest setting. Each time you cut the grass, you should only cut of the height of the grass. Instead of cutting it closely, let the grass grow thick and lush, as newly grown grass is weaker and more susceptible to fungal infections. Although you will have to work harder, your lawn will look better if it isn't cut too short.
   • Keep lawn mowers blades clean and sharp.
   • Cut the lawn a little shorter than usual before snow falls to prevent snow mold.

5. 

   Rake off dead vegetation on the lawn. This litter usually consists of grass, leaves, roots and branches that cover the ground. The soil needs to have ventilation to fight fungal infections, so cleaning up litter can help prevent mold.
   • Ideally, you should use a gasoline-powered litter cleaner. You can rent this at a farm tool rental store.
   • Trash removal is usually done in the spring.
6. Till the soil annually to loosen the soil. The soil excavation stage will help the soil to be loose, porous, and not too compact. This is very important and should be done at least once a year to make sure the water, fertilizers and drugs can get into the soil. Otherwise, the roots of the grass may not be able to fully absorb the nutrients and medicines.
   • You can rent a tiller to loosen the soil.

7. 

   Sprinkle mulch every year after you plow the soil. The mulch is a fertile, well-drained material that improves soil quality. These materials generally include coarse sand, humus, peat or compost. Mulching will help grass grow stronger and better drain, and prevent high humidity. Spread mulch onto the yard and scratch the ground evenly.
   • Before spreading the mulch, you need to remove the litter and loosen the soil.

Advice

• Choose a grass suitable for the climate and soil. Native grasses are highly resistant to native fungal spores. Many foreign grasses are weak against native fungal spores.
• Brown spots on the yard may not be mold. This can be caused by other causes such as dry weather, barren soil, infestation with pests or animal damage.

Warning

• Be careful when using chemical fungicides, as they can be harmful. For best results, keep the chemical handling area in isolation for days after use.
• Keep people and pets away from the lawn during and after using the fungicide.
• Use all fungicides carefully and correctly according to the instructions on the product packaging.
