How does Summer Patch primarily present itself on affected turfgrass?

Summer Patch primarily presents itself on affected turfgrass as yellow to tan patches. This distinctive color change occurs due to the pathogen causing the disease, which affects the grass during warmer temperatures, particularly when conditions are humid and the soil is warm. The yellowing indicates that the grass is under stress, often as a result of the root system being compromised, leading to a decline in overall plant health.

As the disease progresses, these patches can become more pronounced and expand in size, sometimes coalescing into larger areas of affected turf. The early signs are crucial for identification and management, as addressing the issue promptly can help mitigate further damage to the lawn.

In contrast, other symptoms or appearances, such as dark brown patches or small white spots, are indicative of different turfgrass issues or diseases and not characteristic of Summer Patch. Dead roots beneath the surface might be a consequence of various pathogens but are not a direct visual symptom of Summer Patch itself.
