## Abstract

Bacterial spot disease in peaches, also known as bacterial shot hole disease, with Xanthomonas arboricola pv. pruni (Xap) as the causal agent, poses a significant threat to peach yield and quality due to its long latency period, rapid onset, and difficulty in control. This article presents the first systematic review of research on the peach bacterial spot pathogen, Xap, comprehensively integrating the latest advances in disease distribution, pathogen identification, integrated control strategies, and mechanisms of pathogenesis and host resistance, thereby forming a complete and up-to-date knowledge framework. The aim is to provide a reference for the control of peach bacterial spot disease and to promote the sustainable and rapid development of the peach industry.
