Biological Guardians: Unveiling Microbial Solutions to Combat Cannabis sativa Fungal Pathogens

초록

Cannabis (Cannabis sativa L.) is one of the earliest cultivated crops and is valued for its medicinal compounds, food, fibre, and bioactive secondary metabolites. The rapid expansion of the cannabis industry has surpassed the development of production system knowledge. The scientific community currently focuses on optimising agronomic and environmental factors to enhance cannabis yield and quality. However, cultivators face significant challenges from severe pathogens, with limited effective control options. The principal diseases include root rot, wilt, bud rot, powdery mildew, cannabis stunt disease, and microorganisms that reduce post-harvest quality. Sustainable management strategies involve utilising clean planting stocks, modifying environmental conditions, implementing sanitation, applying fungal and bacterial biological control agents, and drawing on decades of research on other crops. Plant–microbe interactions can promote growth and regulate secondary metabolite production. This review examines the recent literature on pathogen management in indoor cannabis production using biocontrol agents. Specific morphological, biochemical, and agronomic characteristics hinder the implementation of biological control strategies for cannabis. Subsequent investigations should focus on elucidating the plant–microbe interactions essential for optimising the effectiveness of biological control methodologies in cannabis cultivation systems. © 2025 by the authors.
