Chlorotic dwarf is a serious disorder of eastern white pine (Pinus strobus L.) in young plantations. Diseased trees are stunted, with mottled foliage, and have only the current-year needles. In a series of experiments in which chambers were erected around living trees to regulate airflow and filter out pollutants, it was found that dispersoid pollutants, through their harmful effect on foliage of genetically susceptible white pines, are responsible for chlorotic dwarf. Ambient levels of ozone and sulfur dioxide, singly and in combination, promoted early symptoms of premature defoliation and needle mottling on susceptible ramets in fumigation chambers. Forest Sci. 16:46-55.
