WHO CAUSES IT?
Xanthomonas vesicatoria is a phytopathogenic bacteria that causes the disease known as bacterial scab in pepper. This bacterium has a complex life cycle that begins with the penetration of plant cells through the stomata of the leaves. Once inside the host, it reproduces and colonizes plant tissues, forming necrotic lesions that extend along the leaves, stems and fruits. Xanthomonas vesicatoria can survive in soil, in the remains of infected plants and in contaminated seeds, which facilitates its persistence between growing seasons. In addition, it can be transported by irrigation water, wind, agricultural tools and insects, which contributes to its dispersion and increased incidence of the disease.
