Bacterial spot of pepper and tomato can spread extremely quickly with infected plants showing symptoms 3–5 days after exposure to the pathogen. [5] Starting with one infected plant, susceptible neighboring plants can show symptoms in as little as two weeks and an entire field can become diseased in as little as ten weeks. [8]
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.
It is a parasite of plants including pepper and tomatoes, causing spots on infected leaves and fruit. [1] X. perforans shows most growth at temperatures of 25-30C. [2] It is widespread, but mostly found in North and South America. [3]
Further investigation of pathogenicity profiles and multilocus sequencing typing suggested that the list could be narrowed down to just three main pathovars with the different symptoms being black rot, leaf spot, and bacterial blight. [8] Both X. campestris pv. campestris (known for causing black rot of crucifers) and X. campestris pv.

[citation needed] Bacterial spot of peaches is caused by the bacteria Xanthomonas campestris pv. pruni. Spots may form on the leaves and they can be mistaken for peach scab, which is caused by a fungus. [citation needed]
An example is Xanthomanos vesicatoria, which causes bacterial spot of tomato and pepper, that is now resistant to streptomycin. Apart from chemicals, alternative management methods include using bacteriophages , bacteriocins , and heat therapy.
