How To Treat Brown Patch Fungus With Infuse

The fungus thrives on conditions that leave your lawn damp for 48 hours or more, making mid-late summer prime time for it to thrive with damage rearing its ugly head in the fall. Not to mention excessive irrigation, rainfall, and humidity all exacerbate the problem. For this reason, water management is key to preventing brown patch. Irrigation should only be used to supplement rainfall. Rain sensors and smart controllers solve for this and ensure youre not overwatering.

One of the toughest parts about treating brown patch is that its likely to reoccur in lawns that have previously struggled with the fungus. If your lawn tends to be affected by brown patch annually, your landscape partner will probably prescribe a prophylactic fungicide application in the fall, with follow-up applications at regular intervals as the weather continues to cool.

Even if your lawn has been spared, you should still remain vigilant. Brown patch can remain dormant in soil for years until favorable conditions are achieved. In fact, some properties that struggle with brown patch might notice signs of infection subside when the weather warms, only to return later in the year when conditions become favorable once more.

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.

  • Identifying brown patch disease
  • Brown patch species of fungus normally attacks the base of the grass blades close to where the plants meet the soil. As a result, the base of the leaf blades rot and have a distinctive dark shade. You can also sense a decaying smell if you pull out the affected blades and hold them close. Meanwhile, youll also notice that the affected leaf blades tend to pull away from the plant without much resistance. The roots, however, usually wont show any signs of damage.

    After a while, the problem spreads from the base of the grass blades t the rest of the blades, resulting in reddish-brown patches as the leaves die. With time, these brown patches can extend for up to several feet in diameter, leaving you with an unsightly lawn.

    How To Prevent Brown Patch Fungus in St. Augustine Grass

    Since the fungus will lay dormant in the warmer months, one of the important things to do in fall is to make sure your lawn isnt a hospitable fungus environment. Piles of debris and old leaves make a cozy little hovel for this invader to lurk around in and matted, thatched grass also provides it with a safe spot to hide.

    Raking up leaves and stick piles, and dethatching your lawn by pulling a rake through it will help keep things clean with good air circulation. Damp, dark places with no air circulation are pretty much the perfect breeding grounds for fungi. If youve had recurring problems with fungal growth in your lawn, you can also use a preventative fungicide if necessary.

    Maintaining a consistent watering schedule for your lawn is a good idea as well. Fungus likes moisture, so if youre drenching your lawn so much that the water doesnt fully evaporate, youre in for some trouble. However, if you water early in the morning and give it enough time for the afternoon sun to dry it up, your grass will be much better off. If you notice that your grass is quite dewy one morning, then theres no need for additional water at that time.
