TL;DR
Turf disease pressure is the degree to which current conditions favor fungal lawn diseases, a function of temperature, humidity, leaf wetness duration, thatch, and the grass species present. Warm nights above 70 degrees with long dew periods send brown patch and dollar spot risk climbing in cool-season lawns, which is when preventive fungicide programs time their applications.
What it means
Turf disease pressure is the degree to which current conditions favor fungal lawn diseases, a function of temperature, humidity, leaf wetness duration, thatch, and the grass species present. Warm nights above 70 degrees with long dew periods send brown patch and dollar spot risk climbing in cool-season lawns, which is when preventive fungicide programs time their applications. Lawn care companies track it through weather models and historical patterns, because spraying after symptoms appear costs more and saves less turf.
