It starts as yellow, tan, or brown of varying sizes in the lawn. It consists of rings that grow over time with a difference in diameter and will quickly fill your lawn with patches. Fungus is a fungal infection that can be caused by a number of different fungi, such as Cryptococcus neoformans, Candida albicans, Aspergillus fumigatus, Trichoderma spp., and others.
The most common fungi that cause fungus in lawns are the Ascomycetes. These fungi are responsible for the majority of lawn fungus infections. Other fungi can also cause lawn fungi infections, but they are less common and are not as likely to cause damage to the turf.

Will grass fungus go away on its own?
The lawn fungus won’t go away on its own. Depending on what you see on your lawn, treatment may be different. You can use a fungicide to stop its growth. Good turf management can help you against lawn fungus.
What is a natural remedy for lawn fungus?
Mix one tablespoon of baking soda with a gallon of water. The affected areas should be sprayed every three days. Both smothering plant pests and keeping fungus under control can be accomplished with the last two options. Although it is safe for use on lawns, turf, and trees, it is not recommended for indoor use.
When should I apply fungicide to my lawn?
Lawn fungicide or fungus control can be applied to the lawn after brown patch has appeared, but it is best to take preventative action and begin applying fungus control for the duration of the summer months. When nighttime low temperatures rise above 60F (16C), we recommend beginning lawn fungicide applications. Fungus control is most effective when applied in the late afternoon or early evening, when temperatures are at their lowest.
The best time to apply fungicides is when the soil temperature is at its lowest and the humidity is the highest. Fungicide application should be done in a well-ventilated area, away from any sources of moisture, such as trees, shrubs, and grasses. If the area is too small to be covered with a lawn mower, it may be necessary to use a hand-held sprayer to spray the affected area.
How does grass fungus spread?
Fungus often develops because water stays on the leaf surface far too long. Mycelia (or the vegetative part of fungus) use the water as a “highway” to travel from leaf-to-leaf. This makes it possible for the fungus to spread to other parts of the plant. I know if my plant is infected?
The first sign of a fungus infection is a change in the appearance of your plant’s leaves. If you notice any of these changes, you should immediately remove the infected plant from your garden and contact your local Cooperative Extension office for advice on how to prevent future fungus infections.
Does aeration help with fungus?
Cool temperatures and moist conditions are good for the growth of fungus. Proper aeration promotes soil drainage, which also helps prevent root rot. Fungus spores can survive in moist soil for up to a year, but they will die if the soil dries out. Soil should be aerated at least once a week to maintain a healthy environment for fungi to thrive.
Can a lawn mower spread fungus?
Yes, lawn mowers can spread fungus. Fungus can attach to the deck, cutting blade, and wheels, and quickly spread out and contaminated different parts of the lawn. To reduce the chances of your lawn mower spreading fungus, make sure to clean it properly and maintain a clean environment.
