the combination of H. uvarum and SA or SBC is more effective to control postharvest diseases of grape berries than the single treatments or the control. It may provide a reliable solution for control of postharvest gray mold of grape fruit. Moreover, the combination of SA (or SBC) with H. uvarum overcomes the limitations of each individual treatment. Thus, the increase in enzyme activity and the extension of storage time of grape berries by the yeast combined with chemical reagents demonstrated here suggests that the application of the H. uvarum combined with SA or SBC could be considered for use during commercial storage.
