The ability of soil drench applications of benomyl to protect pinto bean plants from injury by peroxyacetyl nitrate (PAN) or combinations of PAN and ozone was tested. Following a 7-day treatment with 0, 60, 80, or 100..mu..g benomyl/g soil, 15-day-old pinto beans were exposed to 745 ..mu..g/m/sup 3/ PAN and 492 ..mu..g/m/sup 3/ ozone for 3 hours. Benomyl did not protect the young primary leaves of these plants from either pollutant regime. When 20-day-old plants were exposed to the same dose of ozone and PAN following a 7-day benomyl treatment, the older primary leaves were protected. 22 references.
