Are you noticing circular patches of dead grass on your St. Augustine lawn? If so, you may be dealing with Large Patch Disease, which is caused by the Rhizoctonia solani fungus. In this video, I’ll explain the causes of this disease, how to recognize it, and the best ways to treat it.
St. Augustine grass is frequently affected by Large Patch Disease, a soil-borne fungus that thrives in warm, damp environments. Brown, stunted, and sparse grass in circular patches with a yellowish halo is a common symptom of this disease.
The roots and crowns of the grass are attacked by the fungus, resulting in the demise of the affected plant. The development of unsightly, large patches in the lawn is the outcome of this, hence the name Large Patch Disease. If left untreated, the disease can spread quickly and become difficult to manage.
Over-watering or inadequate drainage, as well as high humidity and warm temperatures, can contribute to the onset of Large Patch Disease. Other factors include overuse of nitrogen fertilizer, overcrowding of the grass, and mowing the lawn too short, which weakens the grass and makes it more prone to disease.
To prevent Large Patch Disease, it’s critical to maintain a healthy lawn by utilizing sound cultural practices such as proper watering, fertilizing, and mowing. Furthermore, reducing humidity levels in the lawn and avoiding over-fertilization can aid in preventing the disease’s development. If Large Patch Disease has already manifested, fungicides are available to aid in its control, but it’s important to follow the instructions carefully and reapply as required.
