India from oil palm to oil palm and yellow leaf disease (YLD) affected arecanut to oil palm was attcmptcd using dodder laurel, Cassytha filiformis L. Positive transmission by symptom reproduction was observed in five oil palm seedlings after 10- I8 months of bridging to SRD-affected oil palm and two out of four oil palm seedlings bridged to YLD affected Areca palm. Electron microscopic detection of phytoplasmas in all the seedlings which have expressed symptoms confirmed the transmission of this disease.enOil palmspear rot diseasephytoplasmayellow leaf diseasetransmissionetiologyStudies on spear rot disease of oil palm in Kerala, India I.
