Antiozonant-Treated Cloth Protects Tobacco from Fleck.
Tobacco is protected from fleck, caused by high concentrations of atmospheric ozone, by enclosing groups of the plants completely in tents of cloth treated with the antiozonant 4,4'-dioctyl diphenylamine in butyl latex. The treated cloth also reduces the amount of fleck on adjacent, unenclosed plants. Spraying the antiozonant on the walls of a previously untreated tent prevents subsequent flecking of plants within the tent.
