The main sources of primary infection for Xanthomonas spp. species, which cause the disease called bacterial spot of tomato and pepper, are infected seeds, as well as infected seedlings for planting.  Bacteria can survive on and inside the seeds for a very long time, from a few months to 10 years, and plants that grow from infected seeds, even if initially are asymptomatic, when  favorable conditions  for the development of phytopathogens are met, such as heat and humidity, it begins to show symptoms of the disease. For the detection and identification of bacteria Xanthomonas campestris pv. vesicatoria were performed analyses according to the flow diagram of the OEPP working protocol PM 7/110 (1) from 2013. Sample came from a crop set up using seeds from the previous year's crop and was consisted in fruits and leaves of Kapia peppers, Elephant Ears variety (Slonovo Uvo) was taken from a farm in Argeş County, Leordeni village in August 2019. Seeds kept by farmers from contaminated tomato and pepper crops and used as propagation material in the following years increase the danger of the spread of this phytobacteriosis and affects production and fruits quality.
