How does Xanthomonas infect peach trees?

Xanthomonas is a genus of bacteria that can infect peach trees, causing diseases like bacterial spot and bacterial canker. Infection typically occurs through natural openings or wounds on the tree, such as leaf stomata or pruning cuts. The bacteria can also be spread through contaminated tools, rain splashes, or insect vectors. Once inside the peach tree, Xanthomonas colonizes the xylem vessels and multiplies, leading to the development of characteristic symptoms such as dark, water-soaked lesions on leaves, stems, and fruit. The bacteria thrive in warm and wet conditions, making the infection more prevalent in regions with high humidity or frequent rainfall. Effective prevention and management strategies involve implementing proper pruning techniques, avoiding over-irrigation, and applying copper-based bactericides to control the spread of Xanthomonas.
