What type of weather conditions does dollar spot favor?

Dollar spot disease is particularly favored by warm and humid weather conditions. This fungal lawn disease thrives when temperatures range from 60 to 90 degrees Fahrenheit, and it is most prevalent when humidity levels are high. The combination of warm temperatures and high moisture creates an ideal environment for the pathogen responsible for dollar spot to infect grass.

In contrast, cold and dry weather, hot and dry weather, and cool and dry weather do not provide the conducive conditions for the proliferation of this disease, as lower temperatures and insufficient moisture reduce fungal activity and growth. Understanding the environmental preferences for dollar spot is crucial for timing management practices such as irrigation and fungicide applications to prevent outbreaks.
