The purpose of this study was to evaluate the effect of biocontrol agents against Sclerotinia sclerotiorum in garlic phenols and thiosulfinates content, and antioxidant activity. The results showed that the lesion diameter is correlated with the bioactive compounds. Garlic cloves presented high phenols content and high reducing power in bigger lesions when treated with Saccharomyces cerevisiae. While in small lesions the thiosulfinates content and the ORAC were high when treated with Bacillus pumilus. The use of bioagents has the potential to increase plant production of bioactive compounds, as well as its antioxidant activity, in addition to promoting pathogen control.
