A flow‐through vapor exposure system was developed to evaluate the effects of 2‐nonanone vapor on the decay of apple slices inoculated with Penicillium expansum Link, and Botrytis cinerea Pers. Treatments with 2‐nonanone at 130 to 300 μL (STP)/L of air at 23°C retarded growth of fungi on PDA. At 300 μLL ‐1 , fungal growth was completely suppressed; however, it re‐grew when transferred to air. At 5°C, exposure to 50 μL.L ‐1 suppressed, and at 100 μL.L ‐1 apparently killed, P. expansum on PDA and apple slices. For P. expansum at 5°C, only 25% of the 2‐nonanone used at 23°C was needed. Physiological damage occurred on the peel of treated apples.
