Which of the following describes brown patch disease?

Brown patch disease is characterized by small circular to irregular brown to straw-colored areas appearing on the leaves or blades of grass. This disease is primarily caused by a fungal pathogen that thrives in warm, humid conditions, often leading to significant lawn and turf damage. The brown patches can vary in size but are typically easy to identify due to their distinct coloration and patterning on the affected grass.

The other descriptions do not accurately capture the specific characteristics of brown patch disease. Light spots and reddish lesions with yellow halos may pertain to different leaf diseases, while wilting and dying plants are more indicative of broader issues such as drought stress or root rot rather than a specific fungal disease like brown patch. Understanding these distinctions is crucial for accurate diagnosis and effective management of turfgrass diseases.
