Dollar spot is most severe in which type of grass?

Dollar spot is most severe in Bermudagrass due to its growth habits and environmental preferences. Bermudagrass thrives in warm, humid conditions, which create an ideal environment for the fungus that causes dollar spot to flourish. This turfgrass species is also frequently used in warmer climates where dollar spot is a prevalent issue.

Additionally, while other grass types can be affected by dollar spot, they do not exhibit the same level of susceptibility as Bermudagrass. Tall Fescue is known for its drought resistance, Ryegrass tends to grow well in cooler temperatures, and Bluegrass, while also impacted, is typically less prone to severe outbreaks compared to Bermudagrass. Understanding the specifics of how different grasses react to pathogens is crucial for effective turf management, particularly when dealing with common diseases like dollar spot.
