Maize is one of the most cultivated species and requires agrochOPemicals for nutrition and pathogen control. Fusarium verticillioides is responsible for damaging plants and stored grains. Plants naturally exposed to stresses have defense mechanisms that are triggered by chemical or biological agents, known as induced systemic resistance. In this study, the yeast Torulaspora globosa (strain CCA6S01) was evaluated as an immune response promoter in maize against F. verticillioides. The treatments started 4 days after maize emergence and consisted of control (saline solution), acetylsalicylic acid (ASA, 100 mg/L), yeast cells (1 × 10⁵cells/mL), or yeast metabolites (cell-free filtrates). After running the treatments, the plants were inoculated with 1 mL of a F. verticillioides suspension at a concentration of 1 × 10⁶ spores/mL. The application of yeast cells provided similar results to ASA treatment, a known …
