Environment
As previously stated F. oxysporum is a common soil saprophyte that infects a wide host range of plant species around the world. It has the ability to survive in most soil—arctic, tropical, desert, cultivated and non-cultivated. Though Fusarium oxysporum may be found in many places and environments, development of the disease is favored by high temperatures and warm moist soils. The optimum temperature for growth on artificial media is between 25-30°C, and the optimum soil temperature for root infection is 30°C or above. However, infection through the seed can occur at temperatures as low as 14°C.

Famous quotes containing the word environment:
“Modern mans capacity for destruction is quixotic evidence of humanitys capacity for reconstruction. The powerful technological agents we have unleashed against the environment include many of the agents we require for its reconstruction.”
—George F. Will (b. 1941)
“Maturity involves being honest and true to oneself, making decisions based on a conscious internal process, assuming responsibility for ones decisions, having healthy relationships with others and developing ones own true gifts. It involves thinking about ones environment and deciding what one will and wont accept.”
—Mary Pipher (20th century)
“In a land which is fully settled, most men must accept their local environment or try to change it by political means; only the exceptionally gifted or adventurous can leave to seek his fortune elsewhere. In America, on the other hand, to move on and make a fresh start somewhere else is still the normal reaction to dissatisfaction and failure.”
—W.H. (Wystan Hugh)
