The effectiveness of the systemic fungicide benomyl (methyl 1-(butylcarbamoyl)-2-benzimidazolecarbamate) and the antitranspirant Folicote (hydrocarbon paraffin wax emulsion) in reducing ozone injury to plants of Phaseolus vulgaris L. Pinto 111 was determined in a series of experiments. Eleven-day-old plants of Pinto 111 were grown in a soil mixture of Hagerstown silty clay loam-peat-perlite (2-1-1) and were fumigated under controlled conditions with 25 pphm of ozone for 4 hours. Results of the fumigation were evaluated 3 days following exposure by determining the percentage area of injured tissue. Fumigated control plants showed flecks on 50-55% of the leaf area. 99% protection was obtained when benomyl was used as a soil amendment at a concentration of 160 ..mu..g/g soil on an air dry soil weight basis. Partial protection was obtained at lower concentrations. Higher benomyl quantities were needed to obtain the same results when applied as a soil drench, although protection was improved when a surfactant was added to the suspension. 99% protection was obtained when plants were sprayed with a Folicote solution alone (10 ml Folicote/1 water). The data demonstrate that ozone injury to plants may be reduced by chemical protectants added to the soil and as a foliar spray. 13 references, 2 figures, 4 tables.
