Dollar Spot is primarily associated with fungal diseases affecting turfgrass. This particular disease is caused by the fungus Sclerotinia homeocarpa, which thrives in conditions that are conducive to its growth, such as high humidity and moderate temperatures. It manifests as small, round patches of bleached grass, resembling dollar-sized spots, hence its name.

Management of Dollar Spot focuses on implementing appropriate fungicide applications, along with agronomic practices that can help reduce stress on the grass, such as adequate mowing, watering, and fertilization. Since the question aims to identify the fundamental cause linked to Dollar Spot, understanding that it is a fungal disease is crucial for effective turf management strategies.

The other aspects, while they can influence overall turf health, do not specifically relate to Dollar Spot as a primary factor. For instance, soil quality can impact turf health, but it is not directly causing this particular disease. Insect infestations may harm turf but are not related to Dollar Spot’s incidence. Similarly, watering practices can affect turf but do not directly associate with the dollar spot fungus, although improper watering may exacerbate conditions that lead to this disease.
