Sulfur dioxide injured the foliage of all the plants tested. Injury in the form of brown or withered areas usually appeared first along the margins of the leaves, then between the veins. Regions along the main veins frequently resisted high concentrations. After a one hour treatment in 3-4 ppm of SO/sub 2/ leaves were injured on tomato, salvia, coleus, geranium, castor bean, roses, and several other plants. The same plants in a slightly wilted condition were not injured by 8 ppm after a five hour treatment. Middle-aged leaves were more sensitive than either young or old leaves. Orchid foliage showed no injury after a four hour treatment in 70 ppm, but a high concentration for a longer period injured the leaves and some of the exposed roots.
