Grass Brown Patch Disease

Amazing Blades Landscaping, the premier professional landscaping company along South Carolina's Grand Strand, urges residents to keep an eye on their lawns for signs of Large Patch in warm season turf-grass.

Large Patch, or rhizoctonia solani AG 2-2 LP, is a specific form of R. solani that affects warm season grasses in the late fall or early spring. A separate strain of the fungus causes grass Brown Patch, a disease presenting on cool season grasses in the late spring. Large Patch is characterized by mostly circular patches of turf that are yellow, tan or straw-brown in color. Typically, patches appear 2-3 feet in diameter, but can rapidly expand to 10 feet or more in diameter. Hence, the name.

Amazing Blades' lawn care maintenance professionals are well educated on the cause and treatment of Large and grass Brown Patch disease. They are treatable turf diseases, but as with most grass diseases, the sooner they are identified and the sooner that treatment begins, the easier and faster it can be eradicated from your lawn by a commercial and residential lawn and landscaping company such as Amazing Blades. Large Patch typically takes hold on susceptible lawns when temperatures drop below 70 degrees in the fall. Unfortunately, the impact only becomes evident when greening of the lawn begins in the spring. The disease thrives in lawns with poor soil drainage, too much rain and those with mowing heights that are too low (a common mistake for many homeowners who care for their own lawns.).

Common grasses impacted by Large Brown Patch include:

  • Bermuda grass
  • Centipede grass
  • Seashore paspalum
  • St. Augustine grass
  • Zoysia grass

Bermuda usually recovers quickly with proper lawn maintenance and treatment from Amazing Blades. Although it will recover, it often takes weeks or even months before centipede, seashore paspalum, St. Augustine and zoysia bounce back. According to the North Carolina State Turfiles Centre, fescues and bluegrass are immune to large patch and can be planted where cool season turf grasses can be maintained, which is unfortunately not in our warm South Carolina climate.
