Canker which is caused by Xanthomonas pv citri (Xac) is a potential threat to the successful production of citrus throughout the world. Due to sudden climatic variation, pattern of disease appearance is changing in different climatic zones. Fluctuation in climatic conditions imposes a pronounced impact on the reproduction rate and enhances aggressiveness of the bacterium. Variation in environmental situation of various citrus zones causes mutations in Xac and produces various pathotypes. So its need of the hour, not only to identify these pathotypes by using modern approaches but also to understand biology of different isolates for devising concrete tactics towards citrus canker. This paper analysis the existing state of information and understanding regarding epidemiology, biology, taxonomy, strains of Xac and latest management practices towards citrus canker.
