When and why does Pythium blight occur?

When temperatures in the evening reach an average of 68 degrees or higher and dew sticks around for about 14 hours, Pythium blight is known to occur. Generally, the disease attacks perennial ryegrass, creeping bentgrass, and annual bluegrass. It can also attack Kentucky bluegrass and tall fescue, but these types seem to be more resistant to the fungus.

The signs of Pythium blight include:

  • Small spots of grass that appear slimy and dark
  • Shriveled grass blades as the spots turn from green to brown
  • White cotton-like structures emerging from the grass in early morning hours
  • Streaks of damaged turf that follow drainage patterns and/or mowing patterns

The disease loves moisture-rich areas and can develop in golf courses, residential lawns, and other areas of grass.

How do we prevent or control Pythium blight in Pennsylvania?

The easiest way to prevent Pythium blight in Pennsylvania is by adjusting the watering schedule during the times that you know the grass is more prone to catch the disease. Make sure your grass does not get too much moisture in the heat of summer. You can do this by watering in the early morning instead of the evening when water would sit on the grass all night. If there are any areas with poor drainage, consider having that area regraded to fix it.

Areas that are prone to Pythium blight can catch it again from year to year, so if you want to fully avoid it, it may be best to switch to a different type of grass in your lawn such as Kentucky bluegrass or tall fescue, as these are not as susceptible and will not have lasting damage.

As a last resort, applying fungicide can control and kill off the disease, but our experts at Green Turf Care generally try to avoid using these products whenever possible as they can affect the good organisms that are in your soil.
