Fusarium Wilt - Environment

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:

    We learn through experience and experiencing, and no one teaches anyone anything. This is as true for the infant moving from kicking to crawling to walking as it is for the scientist with his equations. If the environment permits it, anyone can learn whatever he chooses to learn; and if the individual permits it, the environment will teach him everything it has to teach.
    Viola Spolin (b. 1911)

    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)

    Today the young actors regard their environment with rage and disgust. They regard their Master not as disciples regard their Master, but as slaves regard their Master.
    Judith Malina (b. 1926)
