Field plots of bean (Phaseolus vulgaris cv. Tendergreen) and tomato (Lycopersicon esculentum cv. Fireball 861 VR) were enclosed in chambers and exposed for 43 or 99 days, respectively, to ambient air or to air from which 60 to 70% of the ambient photochemical oxidants were excluded. Comparisons between these treatments revealed that ambient oxidants at Yonkers, New York reduced the fresh weight yield of tomato by at least 33%, and in bean, the weight and number of marketable pods were reduced by 26 and 24%, respectively.
