The application of ceramide in the control of rice blast fungus falls within the field of biological control. This invention relates to the application of ceramide in the control of rice blast fungus: a combination of ceramide and lipopeptides is used for the control of rice blast fungus. Exogenous addition of ceramide significantly enhances the stress effect of lipopeptides on rice blast fungus. It also enhances the abnormal accumulation of glycogen and lipid droplets in conidia, promotes the bursting of ROS, and increases intracellular ceramide and calcium... 2+ The invention increases the content of malondialdehyde (MDA) in mycelium, enhances membrane lipid peroxidation, and decreases ergosterol content. Furthermore, it inhibits the expression of ergosterol synthesis genes, UPR target genes, and sphingolipid metabolism-related genes. This invention develops a highly efficient natural agent against rice blast by combining exogenous Cer with lipopeptides. This agent effectively reduces the pathogenicity of rice blast fungus and significantly inhibits its infection of rice, laying the foundation for the development of novel biological control agents.
