Like most Septoria species they require moist and humid conditions to germinate, because of their conidia being immotile, and survive during the off-season by overwintering on dead and decaying organic matter. The disease moves to other parts of the plant during periods of rain or heavy wind, which enable the dispersal of ascospores (primary cycle) and conidia (secondary cycle) to roam and infect other vegetative tissue.
