How To Prevent & Combat Lawn Disease in Georgia

In Georgia, the mild climate can lead to your lawn being affected by several lawn diseases. High heat and humidity, which is quite common in most of Georgia, can lead to lawn fungus, brown patches, and lawn disease.

Of course, this depends on the type of grass you use and the maintenance and care you provide for your lawn.  It is important to keep an eye on how the weather and different outside variables can interfere with keeping your lawn looking pristine.

While it can be the priority of your landscaping professionals to protect your lawn, it is important to know how to identify these problems for yourself. One of the first ways to protect your lawn is to identify its condition. So, let us identify with the several types of lawn disease that are more common to Georgia lawns.

Lawn Disease #1: Fusarium Disease

This lawn disease can be identified by small, circular, grayish-green areas that can appear on grass from just a few inches to a foot in diameter. While some plants and grass will survive, the crown and base area of plants in the affected area will show reddish rot and will be hard and tough.

For Fusarium treatment, it should be noted that it can only be managed by prevention and exclusion of the affected area. The fungus usually kills the infected host. One of the most effective treatments is to replant the affected area using different plants than the ones previously infected. Treatment can take 3-4 weeks to contain. Note that this should be investigated during the coming spring before new growth takes place.

Lawn Disease #2: Red Thread

This lawn disease is most common in areas where the weather is damp and humid. The symptoms of Red Thread are easily recognizable by thin reddish-pink patches or strings running through the grass. In severe cases, the lawn may all give off this color.

Red Thread is common during the Spring and Autumn months. It is prevented by routine maintenance on your lawn. Red Thread fungus can be treated by aerating the affected area. This will also circulate air flow for plants and grass and reduce shade to help with treatment. Another treatment course is to over seed the more noticeable patches and uproot affected areas when manageable. 

Lawn Disease #3: Dollar Spot

Dollar Spot Lawn Disease is most seen in creeping bentgrass, perennial ryegrass, Kentucky bluegrass, and zoysia grass. It can be identified by small brown patches that may be slightly shrunk with reddish-brown shading. As the affected area continues to expand, they can become circular in size coining the moniker “Dollar Spot.”

It can be effectively maintained or prevented by normal upkeep of lawn procedures. To prevent Dollar Spot Lawn Disease, it is important to remove dew from the grass and incorporate an irrigation system so that moisture does not build up over a prolonged period. Along with controlling moisture, it is important to apply fungicides to help protect unaffected areas.

Lawn Disease #4: Brown Patch Disease

Brown Patch Disease, also known as large patch disease, is a fungus that commonly occurs during the late summer months. It appears when the weather is hot and humid. Brown Patch fungus can affect both warm-season grasses and cool-weather grasses. It can be identified by discoloring that appears light yellow.

By the time you identify it, the fungus has already taken root. The thing to look at is not the grass which has already started showing the symptoms, but the soil beneath which is the root of the problem. Brown Patch disease is also a reoccurring fungus that easily grows where it is already prevalent. Fungicide is the best option for treatment. But affected areas need to be regrown from the soil up.

Lawn Disease #5: Spring Dead Spot

This lawn disease is found mostly on Bermuda turf and occasionally on Zoysia. The disease can be seen in the spring following periods of long, cold, and freezing temperatures during the winter months. This can be reduced and even prevented with the proper preventative fungicide application in the late fall.

It is important to identify which fungus is affecting your lawn.

Depending on how bad the situation is, your lawn could still be saved by taking precautionary measures. It is important to know the type of grass that can be affected, the time of season, and other outside interference that could help fungi grow. Most of all it is important to do routine maintenance in your yard that would prevent you from missing something that you would not spot by doing irregular maintenance.
