Spreading The Disease
A major way blue mold spreads is by the distribution of infected transplants. Even though they may appear to be healthy they can still hold the infection.Farmers generally buy transplants from other growers, and take risks of possibly buying diseased plants. If these plants are diseased they are risking their other plants of getting blue mold. This can affect their entire region of their tobacco plants. A five- to seven-day symptom-free plant takes place before the first appearance of a diseased plant is visible. When weather conditions are reasonable a second set of spores evolves around a seven- to a ten-day period. If these plants are not chemically treated quickly the cycle may be repeated several times during the growing season. This can cause a huge epidemic causing many plants to be infected. Blue mold has been found to come into play three times each week from March to August

Famous quotes containing the words spreading and/or disease:
“For Occupation—This—
The spreading wide my narrow Hands
To gather Paradise—”
—Emily Dickinson (1830–1886)
“It is useless to check the vain dunce who has caught the mania of scribbling, whether prose or poetry, canzonets or criticisms,—let such a one go on till the disease exhausts itself. Opposition like water, thrown on burning oil, but increases the evil, because a person of weak judgment will seldom listen to reason, but become obstinate under reproof.”
—Sarah Josepha Buell Hale 1788–1879, U.S. novelist, poet and women’s magazine editor. American Ladies Magazine, pp. 36-40 (December 1828)
