Research Progress of Application of Biological and Natural Preservatives in Controlling Post-harvest Grape Gray Mold

The decay of postharvest table grapes caused by the gray mold infection can be controlled effectively by the use of conventional sulfur dioxide fumigation and other chemical antifungal agent treatments,moreover,which can also inhibit the browning of grape rachis and fruit stem. However,with traditional sulfur dioxide fumigation treatment,surface residual bleaching problem of grape berry can be induced,even more has a negative effect on the flavor of the table grape,consequently,the food and environmental safety hazards will be initiated. In this paper,the grape grey mould character and postharvest disease symptoms of grey mould were expounded,meanwhile,the current alternatives to traditional chemical antifungal sulfur-free biological and natural preservation control methods were systematically summarized. Meanwhile,an outlook of the application prospect and development direction were proposed,aiming to provide a reference for the non-pollution control of grape grey mould and the practical application of grape storage and preservation.
