Abstract When the leaves of 4- to 6-weeks-old papaw seedlings were mechanically inoculated with sap extracts containing tobacco ringspot Nepovirus (TRSV), tobacco streak Ilarvirus (TSV), tomato spotted wilt Tospovirus (TSWV), lettuce necrotic yellows Rhabdovirus (LNYV) or solanum nodiflorum mottle Sobemovirus (SNMV), infection of some of the papaw seedlings resulted with TRSV,TSWV and TSV, but not with LNW and SNMV. However, LNW was transmitted to papaw seedlings by its aphid vectors, Hyperomyzus spp., without causing symptoms. Symptoms produced by TRSV and TSWV were similar, but not identical, to those shown by plants with naturally occurring Australian dieback disease. Infection by TSV caused a mild mottle. It is concluded that none of the five viruses is the likely cause of Australian papaw dieback disease.
