The antioxidant N-(2-(2-oxo-1-imidazolidinyl)ethyl)-N'-phenylurea (EDU) was compared with carboxin and benomyl, two fungicides with antioxidant properties, for effectiveness in suppressing ozone injury on navy beans (Phaseolus vulgaris). EDU was most effective in reducing bronzing and delaying leaf drop, and increased yield by up to 36%. Part of the yield increase was due to larger seed size. The effectiveness was affected by timing of applications of the antioxidant, the amount of bronzing on the crop, and the sensitivity of the cultivar to ozone. 8 references, 2 tables.
