In addition to humidity and favorable temperatures, too much nitrogen and water are the main factors contributing to the appearance of brown patch. Poor soil drainage, a build-up of thatch, and compacted soil are other factors that favor brown patch fungus.

Great lawn care will choke out all invaders, and make it much harder for fungus to grow. Fortunately, the right lawn care practices can go a long way toward prevention and treatment and in severe cases, a fungicide can help eradicate the spores to keep it from spreading.

Symptoms Of Necrotic Ring Spot
A lawn with the NRS fungus will have brown spots with the texture of healthy grass. Its not dry and brittle. The ideal conditions for NRS include cool and moist conditions, between 55 and 83 degrees Fahrenheit, although symptoms may more readily be apparent in summer heat or drought conditions.
Frequently, the turf will survive the infection and re-grow in the center of the patches, giving them a ring-like frog eye appearance. In the spring, rings may appear as just a light green color. Other symptoms may include depressions in the soil where rings are present, easily-pulled roots or Hyphae in the roots, which makes the plant more prone to environmental factors.
Does Mowing Spread Fungus
While mowing, fungus can stick to the mower blades and it can spread it all over your lawn from an infected area. It is the reason why professional gardeners and lawn owners do not recommend mowing a fungi-infested lawn. So, make sure that you clean the underside of the lawn mower on every use and set a proper mowing height for your yard to avoid spreading the fungus from one place to another.

Preventing Lawn Disease And Fungus
The best way to deal with lawn disease and fungus is to prevent it from happening in the first place. Often, issues arise due to the way homeowners care for their lawns. Even some well-intentioned habits can cause problems, and making changes can prevent disease or keep it from causing permanent or widespread damage.
Some of the best methods of lawn fungus control to keep disease away include:
- Watering properly. Overwatering can cause mold, mildew and yard fungus to form. Once your grass is established, water deeply but less frequently. Your grass only needs about an inch of water per week. Water early in the day so grass will dry in the sun wet grass is more susceptible to fungus.
- Mow regularly, but dont cut the blades too short. Grass that is too short is more hospitable to disease. Keep your blades sharp so they cut without damage.
- Clean up debris from your yard. Leaving piles of leaves, branches and other debris creates the ideal breeding ground for fungus.
- Improve drainage. If you have low-lying areas or spots that dont drain well, fix them so that water doesnt pool and cause problems.
- Test the soil. Sometimes the problem is due to the nutrient balance in the soil, and changing or adjusting how you feed can solve it.
- Prevent spread by cleaning tools. Clean all of your lawn tools, including mower blades, rakes and shovels with a mixture of water and bleach to kill any spores that could be hiding there, waiting to cause a problem.

What Causes Dollar Spot
Dollar spot fungus occurs in high humidity, especially if there is a restricted airflow to the grass.
The fungus itself, schlerotinia homeocarpa, comes from the earth and is most prevalent from early spring right through to the backend of fall when daytime temperatures reach between 59-86°F , and the nights are cool.
The reason the temperature range for infection is so wide is that different biotypes of dollar spot are more notorious at different temperatures.
Turfs with a moist canopy and dry soil are the most susceptible to infection. Low nitrogen fertility in the earth is another reason your lawn might develop a dollar spot problem.
Dollar spot can be exacerbated greatly if areas of your lawn are covered, preventing sunlight and air from drying the buildups of dew on the blades. This excess moisture combined with the ambient humidity provides the perfect catalyst for fungal growth.
Not all grass types are equally at risk from dollar spot. Those particularly susceptible include bents, fine fescues, and annual meadow grass. If you have any of these grasses on your land, you should keep a close eye on them during the humid months.
The good news is that dollar spot doesnt have its own reproductive process or autonomy. This means that it cant spread on its own.
It requires mechanical help, by which we mean it must be physically moved from place to place through the dissemination of already infected plant matter.

Many conditions can cause patches of brown, dead grass on your lawn, but only one gets the official name “brown patch.” Brown patch disease is a condition caused by a Rhizoctonia fungus, usually Rhizoctonia solani. The fungus often appears in mid- to late-summer when the weather is hot and humid. Brown patch is a foliar disease, meaning that it harms the blades of grass but not the crown of the plant or the root system. Grass plants affected by brown patch may recover on their own, without chemical intervention.
Rhizoctonia can affect all cool-season lawn grasses, but it is especially harmful to ryegrass and tall fescue. Kentucky bluegrass and fine fescues can occasionally be affected, but the damage is usually minimal in these species. Brown patch can also affect a variety of warm-season grasses, including St. Augustine grass and zoysiagrass.
Signs Of Lawn Fungus To Watch Out For
Lawn fungus can come about in different forms. Here are a few common signs that youll see in your lawn that might indicate disease.
