Symptoms of diseases caused by Xanthomonas [1] Xanthomonas species can cause bacterial spots and blights of leaves, stems, and fruits on a wide variety of plant species. [15] Pathogenic species show high degrees of specificity and some are split into multiple pathovars, a species designation based on host specificity.
Management of bacterial leaf blight is most commonly done by planting disease resistant rice plants. PSB Rc82 is the standard variety of rice used in Southeast Asia, and the use of this cultivar enables the harvest of an estimated 0.8 million metric tons of rice per cropping season that would have otherwise been lost to bacterial leaf blight.
Bacterial seedling blight of rice (Oryza sativa), caused by pathogen Burkholderia plantarii [4] Early blight of potato and tomato, caused by species of the ubiquitous fungal genus Alternaria; Leaf blight of the grasses e.g. Ascochyta species [5] and Alternaria triticina that causes blight in wheat [6]

incanae (known for causing bacterial blight of garden stocks) are vascular pathogens, and they have been found to invade the plant host through wounds or hydathodes. Xanthomonas campestris pv. campestris also has some limited ability to infect the plant host through the stomata.
