2.4. Ultraviolet-C light treatment
Prior to each experiment, two fruit discs were selected as the untreated, uninoculated controls. After inoculation, four fruit discs were selected as inoculated control samples. Two sample discs were randomly selected for each UV-C light treatments inside a UV-C Emitter™ Table-top System (Reyco Systems, Meridian ID) at a wavelength of 254 nm at 23 °C, as described by Syamaladevi et al. (2013). This equipment consists of an array of two 110 V 16-inch Steril-Aire™ UV-C Emitters™ mounted in a stainless steel hood (0.45 × 0.30 m). The height of the UV-C emitters was adjusted to 0.1 m above the fruit discs during irradiation treatments. A UV radiometer
