Abstract： Tobacco target spot disease is primarily caused by Rhizoctonia solani Kuhn，a pathogen that significantly affects the leaves of tobacco plants. This disease poses a serious threat to both the yield and quality of tobacco. In rent years， prevention and control of tobacco target spot disease have achieved significant progress， primarily through the cultivation of resistant varieties，chemical control，and biological control. Among these methods， biological control not only aligns with the strategic goals of sustainable agricultural development but also demonstrates effective management outcomes. Therefore，this review，through sorting the incidence characteristics and hazards of tobacco target spot disease，recent advancements in biological control strategies，specifically application of Streptomyces， Bacillus species， and Jinggangmycin were mainly expounded. This review summarizes the main microbial species or metabolic products utilized for managing tobacco target spot disease，providing a scientific reference and technical support for precise and sustainable control of this disease.
