The development of spot
lesions was recorded daily during the 10 days of the
experiment where the total number of infected leaves
was recorded to determine the disease incidence as the
percentage of leaves infected.
In all treatments, the
bracts were wrapped with a transparent plastic bag after
inoculation and secured within the greenhouse to
minimize coinfection by unknown bacteria. Each
treatment was run with 3 replicates in which twenty
curcuma bracts were used for each replicate.
