Incidence of potyvirus disease in oil palm nursery seedlings

Author(s): SOLOMON, J J*; KOCHU BABU, M**

Oil palm seedlings raised in some nurseries in Karnataka State, India exhibited mosaic, mottling and ringspot symptoms indicative of virus infection. The incidence was in the range 0.001%-0.01% and was mostly observed in material imported from Costa Rica (ASD). Electron microscopic examination of leaf sap revealed flexuous filamentous particles, ultra-thin sections of symptomatic leaves showed pin wheel inclusions and scrolls in mesophyll tissues, characteristic features of poty virus. This paper highlights the virus incidence in the introduced material and its implications for quarantine.
