Currently, the most effective treatment for bacterial spot of pepper and tomato is a combination of chemical applications. Diseased seeds may be treated with sodium hypochlorite , calcium hypochlorite , or trisodium phosphate to kill bacteria on the surface of the seed. [ 5 ]
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.

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.
Strains of plant pathogenic bacteria becoming resistant to chemicals contributes to the difficulty of managing bacterial leaf spot disease. An example is Xanthomanos vesicatoria, which causes bacterial spot of tomato and pepper, that is now resistant to streptomycin.
The importance of using disease-free seed and/or transplants is highlighted by the fact that "as few as three infected seeds in 10,000 (0.03%) can cause black rot epidemics in a field." [ 6 ] In transplant beds, an initial infection level of 0.5% can rise to 65% in just three weeks. [ 2 ]
Bacterial spot of peppers and tomatoes is caused by the bacteria Xanthomonas campestris pv. vesicatoria. [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]
