  • What Causes Brown Patch Disease

    Lawn Fungus Control | Best Cure for Lawn Fungal Disease

    Of all St. Augustine grass fungal diseases, brown patch causes the most damage to turfs, as it leaves behind large sections of unsightly brown patches over a short period of time. The disease is caused by Rhizoctonia fungus, which finds nitrogen-deficient lawns more favorable. Rhizoctonia also prefer hot and humid conditions, hence the disease advances more rapidly when temperature conditions rise to about 80-degrees Fahrenheit.

    During fall, Rhizoctonia fungi usually hide out in the grass thatch. The cold temperatures and high humidity during this time of the year favors them. As such, once the temperatures drop below 80-degrees Fahrenheit, these fungi start penetrating the grass blades via the stomata, causing stress damage in the process. These fungi are also more likely to appear on your lawn if theres excessive soil moisture due to rainfall or irrigating too frequently. As such, you can make your St. Augustine turf less-vulnerable to brown patch disease by avoiding overwatering and ensuring proper soil drainage.

    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.

    Neem Oil

    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.

    Baking Soda

    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.

    Compost Tea

    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.

    How Do I Prevent Grass Rust

    You can prevent grass rust from showing up in your lawn simply by keeping it well fed. However, you dont have to go overboard with fertilizer.

    Four timely applications of a nitrogen-based lawn food, such as Scotts 4-Step Program, will keep your lawn green and healthy, enabling it to fend off rust and most lawn diseases. Two applications should come after August 1 plan those around August 1 and Sept. 15. Those dates can vary depending upon where you live.

    Proper fertilizing and other lawn care practices, such as proper watering, shade management and core aeration, can keep your lawn healthy enough to resist diseases and other lawn ailments.

    Those grass rust pustules appear mostly on the leaf blades. If you bag clippings as you mow, youll remove some of the infected leaf tissue, improving your chances of keeping it under control. Just dont add clippings of rust-infested grass to your compost pile. Also, if you hire out your lawn care, know that commercial mowers can oftentimes spread it from one lawn to the next.

    When reseeding your lawn, look for a mix that contains rust-resistant varieties. Because many species and varieties mingle in todays grass seed mixtures, you may need help here. Refer to your local lawn and garden extension service for help. Retailers who take selling grass seed seriously may be good resources of information, too.
