摘　　要：Worldwide,fruit is an indispensable treasure house of nutrition for human beings,occupying a vital position of human diet.Postharvest fruit storage requires efficient antifungal agents to control Botrytis cinerea,which is a vital postharvest disease affecting fruit and leading to enormous losses.However,with the enormous abuse of existing antifungal drugs,the problem of drug-resistant fungi is imminent,making the controlling diseases caused by pathogenic fungi even more challenging.Drug repurposing is an efficient alternative method,we evaluated a well-known antifungal chemical,terbinafine,against the agricultural pathogen,B.cinerea in vitro,as a result,terbinafine showed strong anti-fungal activity.Furthermore,the in vivo antifungal activity of terbinafine was evaluated,the results showed that terbinafine could reduce the decay area on grapes.Terbinafine could disrupt the cell membrane integrity,increase cell membrane permeability,and eventual cell death of B.cinerea.In addition,terbinafine reduced decay incidence,and weight loss and maintained the soluble solids,titratable acidity,ascorbic acid,total phenolic,and malondialdehyde content during the storage period of grapes.Overall,terbinafine could be an antifungal preservative for postharvest table grapes fresh-keeping.
