Environment
Though minimal data specific to S. solani is available, Stemphyllium spp. thrive in high humidity (relative humidity of 85-90%), more than eight hours of leaf wetness (caused by rain, fog, or dew) and temperatures near 18°C. Though leaf wetness is important, rainfall per se does not appear necessary if humidity or fog provide sufficient leaf wetness. Presence of debris from the previous season may harbor inoculum and increase disease incidence. Heavy fruiting and good soil fertility also favor disease development.

Famous quotes containing the word environment:
“People between twenty and forty are not sympathetic. The child has the capacity to do but it can’t know. It only knows when it is no longer able to do—after forty. Between twenty and forty the will of the child to do gets stronger, more dangerous, but it has not begun to learn to know yet. Since his capacity to do is forced into channels of evil through environment and pressures, man is strong before he is moral. The world’s anguish is caused by people between twenty and forty.”
—William Faulkner (1897–1962)
“Maturity involves being honest and true to oneself, making decisions based on a conscious internal process, assuming responsibility for one’s decisions, having healthy relationships with others and developing one’s own true gifts.
