Brown Patch Disease Of Lawns Introduction
The beauty of a lawn can be quickly destroyed by brown patch , a serious fungal disease that can affect all South Texas lawn grasses. It can develop rapidly when temperatures are warm and humid, especially during warmer periods of the fall and winter months. Warm-season grasses such as St. Augustine , Bermuda, and Zoysia are most commonly affected by brown patch during the early spring and late fall.
SymptomsSymptoms of brown patch may vary greatly with the type of grass and soil conditions. The disease usually causes thinned patches of light brown grass that are roughly circular in shape. These areas range in diameter from a few inches to several feet. Often the center of the patch will recover, resulting in a doughnut-shaped pattern.
When disease conditions are favorable, large areas of the lawn may be uniformly thinned and eventually killed with no circular patch being evident. This type of pattern is commonly seen on infected St. Augustine grass grown in shady, moist locations.
Close inspection of grass blades reveals small, irregular, tan leaf spots with dark-brown borders in combination of rotted leaf sheaths near the soil surface.
Prevention and TreatmentThe best way to prevent brown patch in the home lawn is by following good lawn care practices. This is much easier and less expensive than the use of fungicides and can be very effective.

Catching The Disease Early
The best way to stop the spread of brown patch fungus in your lawn is to follow the guidance in the previous section, as removing the conditions needed by the fungus to grow will force it back into dormancy. If youve just noticed that the fungus has started to grow, you can fight it back by raking and fluffing the grass in the affected area to speed up the drying process. Then, you should apply an organic fertilizer to provide the grass with a healthy dose of nutrients to fight off disease. This Garden Care Organic Fertilizer from Milorganite can be used on your lawn all year round to keep your grass and plants strong and resistant.
Common Lawn Fungal Diseases
There are quite a few fungal diseases that can impact lawns, but theyre usually pretty specialized, targeting specific lawn types, at certain times of year, under certain conditions. For example:
- Brown patch strikes during hot, humid weather.
- Fusarium blight prefers hot, drought conditions.
- Dollar spot tends to spring up when nights are cool and dew is heavy.
Before treating your lawn, its important to identify not only whether your lawn indeed has a fungal disease, but to identify the fungus itself. All fungicides arent the same, and some diseases can be easily treated by making changes in your lawn care.
Knowing your grass type and recent weather conditions can make it easier to narrow down, but you may need help in figuring out exactly whats going on. Your local cooperative extension center is your best resource for determining which diseases are most common in your area, or you can take a small baggie of the infected grass to your local garden center for help.

Natural Remedies For Lawn Fungus
There are many natural remedies for lawn fungus. These include baking soda solutions, neem oil, and compost teas. For the best results, you should use these natural options early in the season as a preventative rather than waiting to treat your lawn after you already have a fungus.
This is one of the better natural solutions available. Dilute 2 oz of neem oil into 1 gallon of water. Apply 2.5 gallons of the spray solution per 1,000 sq ft. You will typically need to apply this solution two or three times on a 7 14 day interval to ensure effective control.
Using a weak baking soda solution to treat lawn fungus issues can be effective but you must be cautious. Baking soda is a salt and like all salts, can damage your lawn.
Grass type and environmental conditions such as rainfall, air temperature and lawn stress all affect how your grass reacts to the baking soda, so you run the risk of doing more harm than good.
While the use of compost teas are generally considered a good way to increase the organic content of your lawn, research on using them as a natural fungicide is limited. When applied in the spring, compost teas will help to boost the overall health of your lawn and can help your lawn to be less susceptible to getting a fungus in late spring or summer.
However, compost teas alone are usually insufficient in preventing turfgrass diseases.

Excessive moisture on the grass can be caused by a number of reasons, including overwatering, dew, or guttation, which is a term referring to the water that is exuded during the night by the grass blades. To reduce the amount of water you add to your lawn, avoid watering daily, and instead base your watering schedule on the current weather conditions and the ad-hoc water requirements of the grass and soil. Also, the time of day that you water the lawn will have an effect on brown patch fungus growth watering early in the morning before sunrise enables you to remove large droplets of dew and water from the grass blades, thus speeding up the drying of the foliage once the sun has risen.

It has been found that brown patch disease can be more severe in lawns that have soil with a pH level of less than 6.0. You can test your soil pH using a home testing kit or by sending a sample of soil off to a professional laboratory. The results of this test will tell you the soils pH level, in addition to the amounts of nutrients present in the soil. If your soil is less than 6.0, you will need to add a pH adjusting material to raise its pH, lime being the material most commonly used for this purpose.
