↵1 Differences in disease severity between locations were significant. As such, data were combined and means separation performed.
↵2 Anthracnose estimated using the Horsfall-Barratt disease assessment scale (6). The percentage of diseased foliage represents the visual estimate of the percentage of symptomatic leaves within the tree canopy.
↵3 Within each column, means followed by the same letter do not significantly differ according to Duncan’s New Multiple Range Test (p = 0.05).
