Control
Control of white mold on crops can depend greatly on specific cultural practices and the application of chemical sprays. Crops that are highly susceptible to white mold should be planted in well drained soils. Also, properly spaced plants or maintaining growth in the fields will help to maintain good air circulation and create microclimates that are less favorable for disease development (Pohronezny 25). Fields with heavy disease pressure may also be flooded for a period of four to five weeks so as the sclerotia may lose their viability(Pohronezny 25). This may not be a practical measure and may be why chemical sprays are used. Fumigating the soils with broad spectrum fungicides can be effective in controlling sclerotia (Pernezyny, Momol and lopes 23). During the growing season, however, applying contact and systemic fungicides during times of the plants greatest susceptibility (flowering and senescence) will give the greatest amount of protection against disease. Crop rotation with cereals in fields with high levels of disease incidence can help in reduction of inoculums. Rotation should last for at least three years since sclerotia can be viable for at least this long.

Famous quotes containing the word control:
“If someone does something we disapprove of, we regard him as bad if we believe we can deter him from persisting in his conduct, but we regard him as mad if we believe we cannot. In either case, the crucial issue is our control of the other: the more we lose control over him, and the more he assumes control over himself, the more, in case of conflict, we are likely to consider him mad rather than just bad.”
—Thomas Szasz (b. 1920)
“I have not ceased being fearful, but I have ceased to let fear control me. I have accepted fear as a part of life, specifically the fear of change, the fear of the unknown, and I have gone ahead despite the pounding in the heart that says: turn back, turn back, you’ll die if you venture too far.”
—Erica Jong, U.S. author. In an essay in The Writer on Her Work, ch. 13 (1980)
“Knowledge in the form of an informational commodity indispensable to productive power is already, and will continue to be, a major—perhaps the major—stake in the worldwide competition for power. It is conceivable that the nation-states will one day fight for control of information, just as they battled in the past for control over territory, and afterwards for control over access to and exploitation of raw materials and cheap labor.”
—Jean François Lyotard (b. 1924)
