How To Identify, Control, and Prevent Lawn Diseases in Ohio Lawns

While weeds and pests may be the main thing you watch out for this spring, you should also be on the lookout for lawn diseases. The warm and wet weather of spring creates ideal conditions for many of the common lawn diseases in Ohio. At NuLeaf, we like to keep our community informed about risks to their lawn and what they can do to prevent it. Here is a list of the most common types of lawn diseases we have come across in Ohio.brown patch of grass

Brown Patch

Imagine waking up, looking out your window, and seeing your yard covered in small brown spots. That’s how fast brown patch can appear on your lawn. Conditions that favor brown patch are consistently hot, and humid days. Watering too late in the afternoon, having poor drainage, or compact soil can also help promote the growth of brown patch. As the fungus attacks your grass, it will cause your grass to decline and eventually die. This creates an opportunity for weeds to take over. Lawns affected with brown patch can take weeks or months to fully recover. You can take steps to prevent brown patch by setting your watering schedule earlier in the day and overseeding your lawn with diseases resistant strains.

Necrotic Ring Spot

Necrotic ring spot is a disease that will create embarrassing and ugly rings in your grass that range from several inches to several feet in diameter. It mainly attacks cool-season strains such as ryegrass, Kentucky bluegrass, and the fescues. As it destroys the grass on the outer edge of the ring, the grass in the center remains green. Necrotic ring spot is most common in lawns that are experiencing stress from drought or high temperatures. To prevent and control necrotic ring spot follow proper irrigation techniques and aerate your lawn regularly. 

Summer Patchcircles of lawn damaged grass

Summer patch is a disease that attacks the crown and roots of Kentucky bluegrass, annual bluegrass, fine fescues. This root-destroying fungus is characterized by the 1” to 2” round patches of dead grass that appear on the lawns it infects. These patches can grow larger and merge with other patches. Summer patch looks similar in appearance to necrotic ring spot but summer patch is much worse because it destroys both the roots and the grass. Mowing too short and nitrogen-based fertilizers have been shown to help promote the development of summer patch.

Red Thread

Red thread is most prevalent during the mild, cool temperatures of our typical Ohio spring and fall. The fungus begins to grow during periods of prolonged wetness and slow grass growth but has been known to be active in Ohio during every month of the year. It is particularly fond of cool-season grasses such as Kentucky bluegrass and perennial ryegrass. Red thread appears as a reddish web-like substance that forms on the blades of your grass. Walking, mowing, or other activities can cause the spores to release and spread to other parts of the lawn. While the disease does not usually kill your grass, it can definitely ruin its green and lush appearance.

To control red thread, use fertilizers that are high in nitrogen and aerate compacted soil to remove thatch and improve air circulation.
