Fungi (P. megakarya, Pm and P. palmivora, Pp) stored from 15/3/2014 to 17/03/2019. SDW: Sterile Distilled Water and SSS: Sterilized Soil Suspension; +: Present; -: Absent. Aggressiveness values less than 1: loss of aggressiveness; value above 1: increase in aggressiveness. Leaf symptom rating (0: Absence of symptoms; 1: Initiation of small necrotic spots; 2: large number of small necrotic spots; 3: Coalescence of brown-necrotic spots, 4: Large, brown-lesions and 5: Large, uniform, brown-lesions; often expanding).
