What is one of the common indicators of brown patch?

Brown patch is a common lawn disease primarily affecting cool-season grasses, and one of the most recognizable indicators of this condition is the appearance of dark brown circular patterns on the grass. These circular patches typically have a brownish or tan edge, which can help distinguish them from other lawn issues. The patterns often range in size and can expand rapidly under favorable environmental conditions, such as high humidity and warm temperatures.

While yellowing leaves and wilting blades can indicate various other issues such as nutrient deficiencies or drought stress, they are not specific to brown patch disease. Similarly, white mold is associated with a different set of conditions and pathogens that do not relate to the symptoms characteristic of brown patch. Recognizing these distinct circular patterns is key for proper identification and subsequent management of the disease in lawns.
