Abstract
Kava dieback disease was first recorded by Parnham in 1935. While some of the symptoms were suggestive of a virus, no viruses have been detected in kava or any other member of the Piperacae. Present results from dsRNA analyses, immuno-electron microscopy, ELISA, and transmission to Nicotiana tabacum and N. glutinosa showed that cucumber mosaic cucumovirus (CMV) was present in many dieback-affected plants. The virus was detected in 44% of kava samples showing a range of symptoms, and was most common in the cultivar Kava Leka Kula in which 61% of samples tested positive by immuno-electron microscopy.
