Fruits are highly susceptible to postharvest diseases, and the application of biological control (biocontrol) agents has proved to be an effective alternative to artificial fungicides, to prolong their shelf-life. Recently, many researchers recommend the combination of low concentrations of bioactive substances (e.g., antioxidants, fungicides, and antimicrobials) with antagonistic yeasts for postharvest disease control. In this work, we used random-effects meta-analysis to evaluate the efficacy of combined treatments against disease incidence percentage (DI%) in wounded fruits. The combined treatments significantly decreased in vivo DI% (mean of relative disease incidence reduction 65.35, [95 %CI: 59.58–71.12; p = 0.00]), with substantial heterogeneity (I² = 99.99%). Both Begg’s (p = 1.36) and Egger's test (p = 0.26), suggested no publication bias. Based on the meta-regression analysis, storage temperature and the number of pathogens cells inoculated were the main factors that account for significant variations in DI%. Antagonistic yeast combined with bioactive substances represented effective agents for sustainable control of DI in wounded fruits.
