Benomyl soil amendments provided short-term protection from ozone injury for 'Pinto' bean plants repeatedly exposed to ozone at 0.06 µliter/liter (6 pphm) for 5-day periods. Protection was accompanied by varying degrees of benomyl phytotoxicity. Benomyl amendments were not effective in overcoming the long-term deleterious effects of repeated exposures to a low level of ozone on the growth, reproduction, and nodulation of Pinto bean plants.
