Incidence and Histopathological Study of Xanthomonas axonopodis pv. vesicatoria (Doidge) Dye in Chilli (Capsicum spp.) Seeds in Western Rajasthan

Bacterial leaf spot is a destructive disease in Rajasthan caused by Xanthomonas axonopodis pv. vesicatoria (Doidge) Dye. A field and market survey was conducted for the study of incidence location. Dry seed examination 103 samples chilli (Capsicum spp.) belonging to 16 districts that revealed 10–100% (XAV) on Tween-80 medium. Two naturally infected carrying 100% XAV were selected categorized into asymptomatic (06.25–94.25%), moderately discolored (01.75–42%), heavily (01.25–27.75%) seeds. The seeds showed shriveled, water-soaked symptoms their surface, bisecting such types seeds, embryo endosperm necrosis browning. pathogen found confined outer coat layer, particularly at ramnent funiculus few In space between endosperm.
