    Summer Lawn Diseases: Pythium Blight

    Posted by: Stephanie Knezevic on July 8, 2015

    pythium_blight_in_lawnHave you noticed any spots in your lawn that look water-soaked? Or perhaps it looks like there is a layer of cobwebs stretched across a certain area? If so, there’s a good chance that your lawn may have Pythium Blight. This lawn disease is common this time of year when the temperatures are hot and humid during the day and cool off significantly at night. So how serious is this disease and how can you get rid of it today?

    What is it?

    Pythium blight, also known as “pythium disease” or “grease spot,” is a lawn disease that targets mainly cool season grasses. Lawns are most vulnerable to this disease when the temperatures are hot and humid. This disease can destroy your lawn within a few days so you’ll want to recognize and get rid of it as soon as possible.

    How can I get rid of it?

    One main way to treat pythium blight is to use a fungicide. If choosing to use this method, be aware that timing is key. If they weather is supposed to stay hot and humid, you’ll want to apply the fungicide at the first sign of symptoms. There are other methods you may want to consider first, especially since they can help prevent the disease in the first place.

    Control Methods

    There are various other ways you can ensure that your lawn isn’t at risk to get pythium blight. Some of those include:

    • Water control-Your lawn is at higher risk to get pythium blight if there is water left standing on the blades of grass. It’s better to water less frequently, but more deeply. This is better for your lawn and also ensure that there is no water left standing on the blades.

    • Fertilization-Fertilizer rich in nitrogen makes it easier for disease to takeover your lawn, so reduce fertilization during the summer to minimize the risk.

    • Mowing-Make sure you do not mow your lawn when it is wet, and also do not mow patches of lawn that show signs of infection. Your lawn mower can just spread the spores to other areas of your lawn, which will damage your lawn further. Try to wash your mower blades after you mow to keep any spores from spreading.
