For the study of incidence and transmission of diseases of brinjal, a survey was conducted in various fields and market. Dry seed examination of 110 seed samples of brinjal (Solanum melongena L.) collected from 10 districts of Rajasthan revealed asymptomatic (07.75-97.50%), moderately discoloured (02.50-78.50%) and shriveled discoloured (04.25-95.50%) seed samples were studied. The discolouration varied from yellow to brown and black spots on seeds which yielded colonies of Xanthomonas axonopodis pv. vesicatoria on incubation.
