C. gloeosporioides and B. parva were originally isolated from symptomatic fruit, purified, and preserved. Identification of the pathogens was confirmed by Westfalia Laboratories. Isolates were maintained on Malt Extract Agar (MEA) (Biolab, Johannesburg) at 24 ◦C. Spores were harvested after 8 days and suspensions (104 spores/mL) of each pathogen were prepared by adding sterile 1/4 strength Ringer’s solution to colonised Petri dishes.
