Abstract: With advancements in the research and development of plant protection machinery, selfpropelled spray bar sprayers have become one of the most crucial components in this field, and their certified products are constantly changing and improving. This paper aims to summarize the current development status of 3Ccertified selfpropelled spray bar sprayers. Over the past three years, there have been 1 366 newly added preliminary or expanded products for the mandatory certification of plant protection machinery, with selfpropelled spray bar sprayers constituting approximately 70% of this total. Policies such as subsidies for agricultural machinery 3C certification have spurred the development of new products and technologies for certifying selfpropelled spray bar sprayers in China, thereby facilitating the practical application of technologies like multisystem separate control, prevention of liquid interference, drift prevention during spraying, calibration of spray width, and variable control. This paper analyzes the development trends of certified products for selfpropelled spray bar sprayers, indicating a progression towards high efficiency, intelligence, green environmental protection, safety protocols, multifunctionality, and enhanced adaptability in the future. In order to promote the healthy growth of the selfpropelled spray bar sprayer industry, it is proposed to  increase policy support, strengthen research on certification systems, intensify government supervision, improve product operational quality, and actively participate in international cooperation. This paper provides  a reference for the research development and practical application of plant protection machinery.
