Pathogenicity test was carried out with the seven
guava isolates in this study. Fresh, healthy guava
fruits were collected and taken to the laboratory. The
fruits were surface-sterilized with 80% absolute
ethanol and then inoculated with the isolates after
wounding. Inoculation was made by using sterile
5mm-diameter cork borers to create holes on the test
guava fruits. Mycelial plugs were cut from pure
culture plates of the isolates and plugged into the
holes on the fruits. The control fruits were inoculated
with sterile agar plugs. All the inoculated fruits were
incubated at room temperature (28±2oC) and
observed daily for symptom development. Reisolations
were made from fruits showing rot
symptoms and identifications carried out.
