A review of the literature has revealed that although the actual method by which gases injure vegetation is not known, the opening and closing of the stomata regulates the entry of the injurious gases. Several modes of actions are involved, the most plausible of which involves enzyme systems. No information was available in the literature concerning gas damage to Florida citrus. However, in the Bartow area in the vicinity of several new triple-superphosphate plants, citrus trees have developed a chlorotic pattern on the leaves. Qualitative tests of citrus leaf ash from affected trees indicated the presence of fluoride. Shortly after this first observation of chlorosis, additional scrubbing facilities were installed at the plant, and the chlorotic pattern on citrus was alleviated. 20 references, 1 table.
