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:
“It is my duty to prevent, through the independence of Cuba, the U.S.A. from spreading over the West Indies and falling with added weight upon other lands of Our America. All I have done up to now and shall do hereafter is to that end.... I know the Monster, because I have lived in its lairand my weapon is only the slingshot of David.”
—José Martí (18531895)
“Your responsibility as a parent is not as great as you might imagine. You need not supply the world with the next conqueror of disease or a major movie star. If your child simply grows up to be someone who does not use the word collectible as a noun, you can consider yourself an unqualified success.”
—Fran Lebowitz (20th century)
