Abstract
Phyllody is a serious disease ofsesame worldwide and the Present investigation was carried out on transmission of this disease to periwinkle. Infected plants showed characteristic symptoms of witches' broom, stunting, leaf proliferation and bushy appearance. Under field condition, infected plants showed the most common characteristic phyllody symptoms. The pathogen phytoplasma could be successfully transmitted through grafting, leafhopper and dodder from infected sesame to healthy periwinkle plants. Among the methods, leafhopper vector (Orosius albicinctus) mediated transmission of phytoplasma was more efficient from infected sesame to periwinkle plants. Plants raised from infected periwinkle seeds did not show any phyllody symptoms.
