Cultural Management: Preventing Brown Patch Lawn Disease

Brown Spots In The Lawn: Fungus And Disease Options

Since high levels of fast release nitrogen increase disease activity, Spring-Green uses a correct blend of for lawn fertilizing during the warmer months. Mow less frequently during periods of hot and humid weather, this reduces stress and limits the movement of grass disease by being carried on your feet or mower. If possible, increase light and air penetration, or movement, by pruning overhanging trees and shrubs. During cooler seasons, open up the thatch layer with power . If these cultural cures fail, a preventative fungicide lawn treatment program may have to be applied to control this most damaging of lawn diseases.

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 Lawn Got You Down

A brown lawn may be the one thing standing between you and a summer full of fun. Since the beauty of a lawn is largely dependent on its healthy, green hue, anything other color tends to stand out like a sore thumb. Brown spots or patches can be an ongoing source of frustration for homeowners seeking a lush, uniform landscape. Dont let those ugly, straw-colored patches get you down. Fight back against turf diseases and reclaim the healthy, green lawn you deserve!

Rhizoctonia Blight commonly known as Brown Patch is a hot weather turf disease caused by the fungus Rhizoctonia solani. While it can occur on all types of turf, it is most damaging to tall fescue, perennial ryegrass, creeping bentgrass and annual bluegrass.

Many conditions can cause patches of brown, dead grass on your lawn, but only one gets the official namebrown 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.

What the Lawn Is Trying to Tell You: Few lawn problems are as unsightly as seeing your lush, green lawn punctuated with large brown spots. There are several reasons for brown, or even dead, spots in your lawn. Some are obvious, such as a dog doing its business on the grass, but others require a bit more detective work. Grass can turn brown if the soils pH is too high, meaning the soil is too acidic. You can test the pH and add nutrients, like lime or sulfur, which will correct the pH balance. But in extreme cases, you may need to replace the grass and soil altogether.

You can check your soils condition with this rudimentary DIY test:

+ Place a handful of soil into a clean container.

Possible Reasons For Brown Spots In The Lawn

As we mentioned, the potential reasons for having brown spots can be quite vast. While we wont dive into detail on each one, we want to at least share some of the possible reasons why your lawn could be dealing with brown spots. We have a lot of articles already written on many of these topics if you want to read more.

  • Lawn Fungus: As we mentioned before, lawn fungus can definitely cause brown spots on the grass. In fact, a disease called Brown Patch causes brown spots . But we have other common diseases in our region including Rust or Red Thread and Dollar Spot, which can also do this.
  • Mowing the Lawn Too Short: Homeowners are often surprised just how much impact tasks like mowing the lawn can impact their lawn care results. But mowing the lawn too short can put a lot of stress on it and actually cause it to thin out and potentially die. We recommend a mowing height of at least 3.5 inches.
  • Armyworms: A sudden influx of Armyworms was an unprecedented event in the Fall of 2021 , and we had a number of customers calling about brown spots in the lawn due to armyworm damage. We cant be sure what kind of damage these pests might cause in the future but this was a rare instance when these caterpillars literally blew in from storms in the South, in the form of moths.

How To Get Rid Of Brown Patch Fungus On Lawn

How to fix brown patches in your lawn

There are some helpful techniques to reduce the chances of being infected by Brown Patch Fungus, or limit and manage the disease. A healthy turf is much more resistant to disease. By watering your lawn on an as needed basis, rather than just a set schedule, and considering the time of year and rainfall, you can better manage your turf to ensure it is receiving the proper amount of water. Frequent mowing at the recommended mow height is critical to the health of the turf. It is very important that your turf is not cut too short, or scalped. Design your landscape so the turf receives the proper amount of shade. And lastly, proper fertilization from a professional can keep your turf thick, green, and healthy. Maintaining a healthy landscape will make your lawn much less susceptible to disease. To hear more about the specific needs of your landscape, call Hulett Environmental Services for a free diagnosis and recommendation. However, sometimes even with the best landscape management, disease cannot be prevented, and professional treatment is needed.

Chemical Burns From Fertilizer

Another very common reason your lawn is turning brown in spots is overusing or spilling fertilizer or spilling other chemicals on your lawn.

This results in either a chemical burn or a change in pH in your soil, which will cause your grass in that location to die.

Solution

To avoid these types of chemical burns, it is important to use fertilizer as directed and to dispose of other chemicals properly.

Avoid pouring gasoline into your lawnmower on your lawn and instead, do it in the garage or on your driveway.

Too much nitrogen can specifically cause these kinds of burns, whether the nitrogen comes from spilling fertilizer as you turn your broadcast spreader or from animal urine.

Thats right, dogs or other animals peeing on your lawn also kills grass due to the high nitrogen content in their urine.

Encourage your dog to pee elsewhere in your yard or take them on a walk to avoid urine burns on your lawn.

Causes Of Brown Patch

Brown spots shouldnt ruin your chance at having the lawn you want. In order to identify whats at play on your turf and figure out the best plan of attack for treating any discolored areas on the lawn, you must first pinpoint what could be causing the issue. Take a look at the top three culprits behind brown spots below:

1. Turf Disease

There is a long list of turf diseases that can turn an otherwise green lawn off color. These diseases are caused by fungi that live in the thatch and soil, often activated by high moisture, humidity, or mowing the lawn when it is wet. Brown patch, dollar spot, leaf blight, and necrotic ring can all cause areas of the lawn to turn brown. Although these diseases may sound serious, the majority will disappear on their own with improved environmental conditions. In some cases, an application of fungicide may be required. If you arent sure if turf disease is affecting your lawn, its best to contact your Weed Man team for verification. We will provide you with a proper diagnosis and advise you on next steps.

2. Shade

3. Insect Damage

Problem: Circles Pop Up In The Grass

What the Lawn Is Trying to Tell You:

Fungal threads in the soil will initially cause the circle of grass to appear greener than the surrounding grass because there is more decaying organic matter there. The decay is providing nutrients to the soil and giving it more moisture, Cain says. But as the fungus grows and works deeper into the ground, it will eventually starve out the grassroots denying them moisture and nutrients. And, as mentioned earlier, watering after dark should be avoided. Watering in the evenings can create a microclimate and make the fungus even worse, Cain says.

Your first line of defense against these circles is to apply a fungicide to the lawn. And you only need to treat the affected area, not the entire lawn. If that doesnt work, dig up the ring and plant new grass.

4. Problem: Grass Is Matted Down

What the Lawn Is Trying to Tell You: This, too, could be a fungus problem, says Chad Diller, a marketing coordinator for Tomlinson Bomberger, a lawn care, landscape, and pest-control company in Lancaster, Pennsylvania. Consecutive wet nights during the summer are a prime cause of matting, Diller says. If you have an environment of dampness and warm temperatures, it can quickly lead to fungi.

University extensions can help you identify the specific fungus, and then provide fact sheets for treating it.

5. Problem: Grass Wont Grow Under a Tree

To be perfectly honest here: let it go.

What causes Brown Spots in the Summer? | Lawn Fungus Control

The best defense against Brown Patch and other turfgrass diseases is a healthy, hardy lawn. Weed Mans granular, slow-release fertilizer applied at the right time will strengthen your lawn and help it fight off common stressors. Core aeration will also help. Aeration improves soil drainage, relieves compaction, and reduces thatch .

If brown patch is already present on your lawn, try the following techniques:

  • Withhold water from affected areas until the soil dries. Then, practice deep, infrequent watering rather than frequent short periods of watering.

  • Water in the mornings ONLY. This will allow the grass and soil to dry before the sun goes down.

  • Mow frequently at the highest setting.

  • Mow with a razor-sharp blade.

Brown patch can also be controlled with the application of fungicide. To ensure continuous control, fungicides must be applied every 21 to 28 days . Your local Weed Man professional can help you create a disease control program that is right for your lawn.

Dont let your brown lawn make you blue this summer. Effective disease management and the lush, healthy lawn that comes with it are only a phone call away.
