Abstract: As a high-performance, green, low-carbon biomass composite, bamboo scrimber has emerged as a mainstream product in the bamboo industry. However, mold infestation severely restricts its high-quality development. This review systematically summarizes recent advances in the mechanisms of mold infestation and long-lasting anti-mildew technologies for bamboo scrimber, covering pretreatment methods such as physical modification, chemical modification, inorganic nanoparticle loading, and anti-mildew-agent impregnation, as well as post-treatment methods such as surface coating or impregnation with anti-mildew agents. The advantages and limitations of pretreatment and post-treatment are compared in terms of anti-mildew mechanisms, treatment effectiveness, process complexity, and applicable scenarios: pretreatment generally provides relatively longer-lasting protection but requires more complex and costly processing, whereas post-treatment is simpler and suitable for exis-ting products or surface protection, although its durability and leaching resistance still need improvement. Current anti-mildew technologies for bamboo scrimber still face key bottlenecks, including insufficient long-term efficacy (typically less than 6 months outdoors), leaching of anti-mildew agents, and increased costs caused by complex processing. Future research should focus on green anti-mildew agents and fixation technologies, applications of anti-mildew materials, and the establishment of standardized evaluation systems. This review aims to provide theoretical guidance for understanding mold-infestation mechanisms, optimizing anti-mold processes, and promoting the industrial applications of mold-resistant bamboo scrimber.
