St. Augustine fungus is unfortunately common in lawns, especially in the spring season. Some of the top fungi that we see in St. Augustine grass are take-all rot, brown-patch, and Grey Leaf Spot. With the proper attention to treatments, grass fungi can be controlled. Let’s take a closer look at each of these fungus diseases.
- Take-All Root Rot
Yes, this form of lawn fungus is as icky as it sounds! This type of grass fungus can affect St. Augustine and Bermuda grass. When this fungus affects bermuda grass it is often referred to as bermudagrass decline. Take-all root rot can form circular patches of brown, dead-looking grass. If you see patches of straw-colored or brown grass, you may have a case of take-all root rot on your hands! Know that chinch bug damage can also look very similar to take-all root rot but it requires a very different treatment. It is best to call a expert, like Weedex Lawn Care, to diagnosis your lawn to insure the problem is identified correctly lawn issue. If you misdiagnosis the problem, the damage could spread and you risk losing your entire lawn.
This type of fungus infects the stolon, nodes, and roots of the turf, ultimately causing them to die. Oh no! Don’t panic, though— there are treatments for take-all root rot. If you want to try it yourself, you’ll need a good fungicide treatment to suppress the St. Augustine grass disease or the bermudagrass decline. You will also need to do a topdressing with peat moss. It can be a delicate balance to figure out what exact treatment is best for your lawn. Take out the guesswork and call Weedex Lawn Care for a free estimate! (972) 727-9207

Ugh, not this again! Brown patch commonly occurs on the fall in north Texas. Very warm weather with high humidity are favorable conditions for this fungus to spread and become visible. Moisture on the grass blades caused from dew or rain can fuel the increase of this fungus disease. If you see ugly brown patches in your lawn that are either circular or irregularly shaped, it might be brown patch St. Augustine fungus.

It’s time to either call in a professional lawn service (hello!) or try to DIY to remedy the problem.
Here are the three most common causes of fungus in St. Augustine grass.
1. Over-watering your lawn, or certain areas of your lawn, could be causing a lawn fungus to thrive! When you have standing water, it can promote the growth of a lawn fungus.
2. Change in temperature is also a cause! The spring season is a big culprit for lawn fungus in St. Augustine because of all of the ups and downs in temperature. While we love to think of spring as a time of growth and blossoming (which it is!), it’s also a good time to check your lawn for lawn fungus and lawn disease.
3. The fungus can often spread from a neighboring lawn that is infected with a lawn fungus disease.

St. Augustine Grass Fungus Treatment
Let’s take a look at some of the ways that you can change your lawn care habits in order to optimize the health and growth of your St Augustine grass while also looking out for and/or treating any lawn fungus or diseases that could be infiltrating your yard.
Are you trying to treat your lawn infected with a St Augustine fungus? Here are some of our pro tips that you may want to keep in mind when trying out treatments for St. Augustine grass fungus!
- Smart Watering
This one can be tricky to master but so effective when trying to avoid fungus in your lawn! Let’s talk about top tips for watering your grass in the most effective and efficient way so that you don’t end up with any lawn fungus and you don’t break the bank with your water bill. Sounds like a win-win, right?
When watering your lawn, you want to make sure that you do not drench your yard to the point of pooling or building up standing water in any area. Standing water invites lawn fungi to move right in! In order to avoid pooling in your lawn, you will need to be very precise and strategic with your watering plan.
Do you have a rain gauge? A rain gauge is actually an important tool when you are trying to figure out for yourself whether your lawn is being under- or over-watered. When you are setting your sprinkler system to give your lawn an even covering of water, you need to know exactly how much it is getting! Since the required amount of water for St. Augustine is 1 to 1.5 inches per week to maintain health and support growth during the growing season, it’s crucial to make sure your lawn is getting what it needs exactly. If you don’t have a rain gauge to measure it, however, you can DIY it with an empty can!
Bonus Pro Tip: How to make a DIY water gauge:
Take a clean, empty tuna size can and set it in your yard. Run your sprinklers on their current setting. Once they’re done with their cycle, take a ruler, and measure how much water is in the can. If it says anything over 1 to 1.5 inches, you may be overwatering your lawn! This can lead to the development of one of the pesky lawn fungi that we have been talking about. No, thanks! With this information, adjust your watering settings to ensure your lawn is being quenched without pooling. Using this water gauge test can also determine if your sprinklers are properly covering the areas of your lawn. Some sections of your lawn could be getting too much water, and other areas may not have enough water.
- Fungicide Treatment
Finding the right fungicide treatment for your lawn can be a crucial step in tackling a St. Augustine grass fungus! Fungicide treatments help to stop the disease in its tracks. When you apply a fungicide treatment to your lawn, it stops or kills the fungus causing the lawn disease. Applying a fungicide treatment can help you control the spread of the St. Augustine lawn fungus before it infects more of your yard, as well as controlling the disease where it has already infected your lawn. There are many fungicide treatments on the market, and some treatments are only available to professionals.
