Diurnal Release of Airborne Pathogen Spores in Greenhouses via the Synergistic Effects of Relative Humidity and Wind

Advanced Science, EarlyView.
Day‐night cycles trigger sharp relative humidity (RH) shifts in greenhouses. Rapid humidity drops dehydrate Corynespora cassiicola spores, inducing shrinkage, jerking movements, and weakened inter‐spore connections that drive detachment. Wind is essential for dispersal, with even mild airflow enabling rapid pathogen spread. These synergistic effects of
