Environment
As the disease is soilborne, it is not uncommon to find clusters of diseased plants together. The pathogen proliferates in stem tissues when soil has high moisture content and air temperatures from 70-80 degrees Fahrenheit. Rainy seasons promote brown stem rot. When soil is untilled, the disease is more likely to persist in soil. The incidence of brown stem rot is highest at soil pH ~6.3.

Famous quotes containing the word environment:
“White males are the most responsible for the destruction of human life and environment on the planet today.”
—Robin Morgan (b. 1941)
“A positive learning climate in a school for young children is a composite of many things. It is an attitude that respects children. It is a place where children receive guidance and encouragement from the responsible adults around them. It is an environment where children can experiment and try out new ideas without fear of failure. It is an atmosphere that builds children’s self-confidence so they dare to take risks. It is an environment that nurtures a love of learning.”
—Carol B. Hillman (20th century)
“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)
