Research Progress on Antagonistic Antimicrobial Prevention and Control of Grape Postharvest Diseases

During the storage and transportation of grapes after picking, diseases occurs generally, including gray mold, aspergillus rot, rhizopus rot, penicillium rot, etc., which seriously affect its production and commodity value. At present, the control of postharvest diseases of grape still depends on chemical control. Long-term application of chemical fungicides can lead to pesticide residues, environmental pollution, harm to human health, and enhance the drug resistance of pathogenic fungal. Using antagonistic bacteria to control postharvest diseases of grape is a green, environmental and safe method instead of chemical fungicides. In this paper, the postharvest infection diseases and symptoms of grape, the source, application effect and their mechanism of action of antagonistic bacteria, the combination of antagonists with other methods to enhance the biocontrol effect are introduced. The prospect of controlling postharvest diseases of grape by antagonistic bacteria is also discussed.
