Effect of CDAP treatment time on mycelial growth of Alternaria and Botrytis sp. (a) Mycelial growth of Alternaria sp. 5RD1 after culturing at 25°C for 4 days after CDAP treatment, (b) mycelial growth of Botrytis sp. 2RG4 after culturing at 25°C for 3 days after CDAP treatment, and (c) mycelial growth of Fusarium sp. 3RC2 after culturing at 25°C for 3 days after CDAP treatment. The CDAP-10% and CDAP-50% mean that the plasma operation time is operation on during 1 second/operation off during 1 second (concentration of O3 is 2.0∼2.6 ppm) at CDAP-10% and operation on during 5 second/operation off during 5 second (concentration of O3 is 20∼24 ppm) at CDAP-50% per hour for 16 hours.
