Brinjal

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. The standard cultural, biochemical and pathogenicity tests were carried out for identification of the bacterium.
