Inoculation experiment I

1The number of pure cultures in each experiment causing visible disease signs (lesions) on experimental fragments.
2Bacterial isolates causing disease signs were named Pathogen 1–7 (P1–P7).
3Inoculation experiment I was repeated for both isolates from the Marshall Islands (P2, P7) that demonstrated infectivity before ruling out isolate P7 as a possible putative pathogen.
4Infectivity represents the percent of fragments (# exposed/# infected) within each of the treatments displaying visible disease signs (lesions)
5No fragments in control treatments were infected
