Postharvest biocontrol activity of CaCl2 and four yeasts against Penicillium digitatum was tested on Tarocco oranges. All tested organisms (Pichia anomala J121, Pichia guilliermondii NRRL Y18314, Debaryomyces hansenii DBVPG 4025 and Saccharomyces cerevisiae P1.6) significantly reduced mould incidence and severity. Application of CaCl2 enhanced biocontrol efficacy of P. guilliermondii and S. cerevisiae, while it did not significantly affect biocontrol of P. anomala and D. hansenii.
