Abstract
Following the previous report on the effect of methyl thiophanate for reducing the damages of photochemical oxidants on agricultural produce, effective concentrations and time factors were studied, and the results were compared with that of benzimidazole. Spinach and radishes were grown in pots, and 21, 11, 6, and 3 days prior to ozone exposure tests, 6.25-100 micrograms of benzimidazole and 77.5-310 micrograms of methyl thiophanate solutions were injected into the various pot soils. Exposure to 0.25 ppm O/sub 3/ was given for four hours to spinach and for 2.5 hours to radishes. In all cases, benzimidazole showed a remarkable effect on reducing the damages of O/sub 3/, especially when injected 5-11 days prior to the exposure. Methyl thiophanate was very effective for radishes but had no effect on spinach. Whether this was due to an insufficient amount of chemicals or due to its selectivity is not clear at this stage of the experiments.
