How To Maintain Your Lawn To Help Reduce Brown Patch
A healthy lawn is a stronger lawn and will be better able to withstand fungal diseases like brown patch. Follow these guidelines:
- Plant disease-resistant varieties and seed mixtures. For example, Scotts® Turf Builder® Grass Seed Heat-Tolerant Blue® Mix for Tall Fescue Lawns combines improved turf-type tall fescue varieties with a heat-tolerant Kentucky bluegrass to help reduce the impact of brown patch on your lawn.
- Reduce the amount of time the grass blades are wet. When needed, water during the early morning hours. Dont water between 7:00 PM and 3:00 AM, as the blades will stay wet overnight.
- Feed the lawn regularly with Scotts® Turf Builder® Lawn Food. Be sure to follow label directions, as overfed lawns are more susceptible to brown patch.
- Unless it is a controlled-release product, dont apply nitrogen fertilizer when hot, humid weather is expected .
Since wet conditions help promote brown patch, make sure your lawn has good drainage and air flow, and consider pruning overgrown trees to prevent too much shade and increase air movement for faster drying. It may also be helpful to aerate and dethatch the lawn every 1 to 3 years to allow air, water, and nutrients to move more freely into the soil.

Brown Patch Loves Hot Summer
Brown Patch is the most damaging turf grass disease
Brown patch is really a summer lawn disease thats caused by a fungus called Rhizoctonia. The disease begins to show growth when temperatures reach 65°, but the most active growth of brown patch lawn disease occurs at temperatures of 80-85° when humidity levels are very high.
The fungi survive the winter in plant debris and enter the leaf tissue through wounds caused by mowing and through the pores when daytime temperatures get into the 70s. Infected turf grass can go quite a while without showing damage because its actively growing. But, if the daytime temperatures reach the mid 80s and nighttime air temperatures stay above 70°, the grass will be under stress. Then, lawn disease damage can become visible almost immediately.
What Type Of Grass Is Most Susceptible To Brown Patch
Brown Patch lawn disease is a common and widespread problem caused by Rhizoctonia solani fungus. The disease can infect a variety of common turfgrasses, but the most susceptible grass species include perennial ryegrass, tall fescue and the bentgrasses.
Brown Patch can also become a problem to Kentucky bluegrasses in mid-to-late summer during extended periods of high temperature and humidity.

Patch sizes can range from a few inches to several feet in diameter. If brown patch has been active for a while, the spots might also look like patches of good grass with rings of dead or thin grass around them.
Besides yellow, do you notice any other colors in the patchy areas? Brown patch patches can be darker purple or burgundy on the outside, for example. Other signs include irregular tan spots bordered by a darker outline on grass blades, brown and shriveled blades, rotting at the base of the blades, darker blades that look water-soaked, and possibly white, cobweb-like growth around the blades .
Want Faster Results Using Fungicide Early May Be Your Key
Using fungicide early can be an effective way to control brown patch mold. There are many fungicides to chose from, and the one you chose will be largely dependent on what is available in your area, as well as the type of application that works best for you.

Three Most Common Diseases Causing Brown Patches On Lawn
Most of the summer lawn diseases that attack tall fescue and Kentucky bluegrass common in Midwest lawns prefer warm/hot and humid weather. The best conditions for brown patch or Pythium disease growth are daytime temperatures between 80 and 95 degrees F, night-time temps around 65 to 70 degrees F, and high humidity. High summer temperatures combined with late afternoon showers every day in late May through July can be a recipe for disaster for lawns.
There are three types of fungal diseases that our RYAN Pros treat most often. Every tall fescue variety is susceptible to these three diseases brown patch, dollar spot and Pythium blight. Learn how to differentiate between them and what you can do to get rid of these lawn diseases in your yard.
1. What Is Brown Patch Disease?
Brown patch disease appears as circular patches in your lawn.
Brown patch is a common lawn disease found in all cool-season grasses in the U.S. caused by a fungus called Rhizoctonia solani. It appears as brownish-yellow, irregular circular patches that range from 6 inches to several feet in diameter. Brown patch begins to grow when temperatures reach 65 degrees F, but it grows fastest when temperatures reach 80 to 85 degrees F and there is high humidity.
The diseased leaves usually remain standing, and close examination shows tan, irregularly-shaped lesions on the leaves with a dark brown border.
2. What Is Pythium Blight Disease?
Pythium blight appears suddenly and can kill your lawn.

Can My Lawn Grow Back After Brown Patch Pythium Blight Or Dollar Spot
The only way the grass can recover from dollar spot and brown patch damage is for the grass to grow enough that the damaged blades are pushed up and mowed off, revealing new and undamaged blades below. Tall fescue and Kentucky bluegrass grass types grow more slowly as temperatures rise so it would take weeks or months for the grass to recover. And, it may require fall seeding to get the lawn back into shape. Thats why preventing damage before disease development is so important.
The best products for preventing and controlling lawn fungus are very expensive. Understanding turf diseases, their control, and when and how to apply them is very important. To get help with your lawn and protect it from fungus, request an estimate for disease control from a professional lawn care service.
What Time Is It Time To Get A Watch Or At Least A Water Timer Don’t Water At The Wrong Time
Watering the lawn too late in the day will leave the lawn damp at night. This is especially problematic in the cooler months as this is precisely the conditions brown patch mold thrives in.
Instead water in the early morning, preferably at sunrise. This will give the grass blades time to dry before nightfall.

How To Spot The Fungus
The funny thing about brown patch is that it doesnt start out brown at all. In fact, the first signs of trouble are when a circular or oblong pattern of light-yellow discoloration appears in your grass. Eventually, the affected area will turn from orange to tan. It will continue to spread outward, sometimes leaving small green patches at the center. The discoloration is caused when the fungus infects each leaf, causing them to rot.
Brown patch fungus can affect all cool-season grasses, but it is especially harmful to ryegrass and tall fescue. Brown patch also affects a variety of warm-season grasses, including St. Augustine grass, Bermuda, and zoysiagrass.
One of the most frustrating aspects of brown patch is that once you spot it, the damage is already done and the fungus is thriving. The trick to successfully eradicating brown patch is understanding the fungus lives beyond where the eye can see, in your soil. When the conditions are right, the fungus strikes, making preventive measures all the more important.
How To To Get Rid Of Brown Patch Fungus On Grass
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 single species of fungus, Rhizoctonia, that often occurs in mid- to late-summer when the weather is hot and humid.

Keep It Under Control
The good news is that your turf can recover from brown patch. The bad news? You may have to wait until the active growing season to see an improvement in appearance. While a fungicide application can help prevent spread to other areas, spots that have rotted will need to regrow.
Meanwhile, steps should be taken to ensure youre not transferring the fungus to healthy parts of your lawn. Affected areas should not be mowed, as that could cause diseased clippings to deposit elsewhere, spreading the infection. You should also avoid walking over the area so your shoes dont transport the spores. Finally, its important to not apply fertilizer during an outbreak. Sure, youll feed your lawn, but youll also feed the fungus, too.
Because brown or yellow spots can be the result of a number of causes, its important to have your lawn assessed by an experienced landscape professional. If brown patch is confirmed, proper treatment is critical. Self-diagnosis and treatment could make the problem worse.
