Turf Disease Control

When it comes to lawn care, fungus diseases can be some of the most difficult pests to get rid of. Sooner or later, just about every turfgrass area will develop various disease problems. While some are completely benign, others may completely ruin parts of your lawn. At LawnAmerica, we provide effective prevention methods and treatments for lawn diseases. Protect your landscape from the damage caused by these types of diseases.

How & When do Lawn Diseases Strike?

Fungi—microscopic organisms that are found everywhere and are spread by water, air, animals, etc.—usually cause plant diseases. Certain varieties of turf are more susceptible to certain diseases than others, and they are under different cultural practices. That is why one lawn may have a disease problem while another next-door may be fine. Most diseases we see are warm-weather diseases that are more severe during high rainfall and high humidity. May and June are the months when most turf diseases do their damage. During the summer months, the humidity levels are generally lower, unless a homeowner is irrigating excessively. Fall provides another opportunity for fungi to infect turf, especially during rainy periods. At LawnAmerica, we treat for:

  • Spring Dead Spot - Spring dead spot is one of the most troublesome diseases of bermudagrass.  It is caused by a fungus that infects the turf in the fall. However, symptoms do not appear until the following spring with large circular dead spots, which do not green-up with the rest of the bermudagrass.
  • Brown Patch - Brown patch is a problem disease we see from about mid-May through July. This disease typically causes damage to fescue lawns. 
  • Dollar Spot - Dollar spot is a summer disease of bermudagrass and zoysiagrass. Fungicides are usually not justified, as a good application of nitrogen fertilizer should help the turf recover just fine.
  • Large Patch - Large patch is a mid-spring and mid-fall disease mainly infecting zoysiagrass, but that can also infect bermudagrass during extreme damp conditions and mild temperatures.
  • Winterkill - Winterkill refers to any severe damage or death sustained by the turf during the winter months. On average, we can experience fairly severe winterkill of bermudagrass about every 15-20 years or so, with the last bad year being 2001. So, we are about due for a bad year.
