Overview Of Brown Patch Fungus
Brown patch fungus, also known as large patch disease, is a troublesome turf condition caused by the fungal infection Rhizoctonia. It primarily occurs in mid-to-late summer when the weather is hot and humid. The symptoms of brown patch include circular or oblong light-yellow discoloration in the grass, which eventually turns orange and then tan. This discoloration is due to the fungus infecting and rotting the leaves. Brown patch can affect both cool-season grasses (ryegrass and tall fescue) and warm-season grasses (St. Augustine grass, Bermuda, and zoysiagrass).
Symptoms And Causes Of Brown Patch
The occurrence of brown patch in lawns can be distressing for homeowners. Recognizing the symptoms is crucial for proper diagnosis and treatment. The onset of brown patch is characterized by circular or oblong areas of light brown or yellow discoloration in the grass. These patches gradually enlarge and turn orange before finally becoming tan. The infection targets the leaves, leading to their decay and eventual death.
The main cause of brown patch is the fungus Rhizoctonia solani, which thrives in damp conditions for 48 hours or more. Factors such as excessive irrigation, rainfall, and humidity further exacerbate the problem. It’s worth noting that the fungus resides in the soil, making preventive measures crucial to avoid and control brown patch outbreaks. Furthermore, brown patch can remain dormant in the soil for extended periods until the conditions become favorable for its growth and spread.
