Ozone is the principal air pollutant damaging crops in Connecticut. Ozone injury in Connecticut has been found on a number of crops including tobacco, tomatoes, potatoes, spinach, alfalfa, and cereals. This is the first report of ozone damage to celery (Apium graveolens var. dulce) in Connecticut, and perhaps in the United States. On July 7, 1966, celery plants with badly damaged older leaves were found in a commercial garden near Shelton, Connecticut. The injured leaves showed chlorotic and necrotic interveinal areas on their upper surfaces. These areas were slightly depressed. Cross sections of the lesions revealed that the palisade cells were most severely injured. Spinach and carrots growing near the celery showed typical symptoms of ozone damage. To substantiate the diagnosis, young celery plants were exposed to 0.2 ppm of ozone in a well-lighted plastic chamber for 1 to 3 hours. Five days later, these plants developed symptoms indentical to those found on celery in the field. Ozone damage appeared on many crops in southern Connecticut early in July. This injury probably occurred on June 27, when a high concentration of ozone (0.1 ppm) was present in the New Haven area.
