Abstract:

This paper described the research progress of biocontrol microorganisms (bacteria, fungi) and their main mechanisms for the biocontrol of microbial plant pathogens. Meanwhile, this paper also briefly described the symptoms, pathogenesis, and influencing factors of tobacco black shank disease. Based on the current progress of biocontrol microorganisms to prevent and control tobacco black shank disease, this paper suggested future research directions such as broadening the screening scope of biocontrol microorganisms, delving into the molecular mechanisms of biocontrol microorganisms, utilizing genetic engineering technology to enhance biocontrol microorganisms. Moreover, the possibility of combining biocontrol microorganisms with new materials such as nanomaterials was discussed in order to achieve better prevention and control effects.

Key words: tobacco black shank, Phytophthora nicotianae, biological control, biocontrol bacteria, biocontrol fungus
