Several postharvest disease control means alternative to conventional chemical fungicides, such as organic and inorganic salts, will be highlighted in the proposed chapter. In particular, it will comprehensively cover different aspects of the use of salts against postharvest Penicillium decay of citrus. It will be an essential resource for the graduate and postgraduate students, researchers, professionals, supply chain players, citrus industries, and retailers. Organic and inorganic salts have a broad spectrum of activity against a wide range of fungi. In addition, they are easy to apply, inexpensive, safe for humans and the environment, and suitable for commercial postharvest handling practices. Different application strategies of salts, before and after harvest, and combined application (with wax, natural compounds, and fungicides, etc.) will be also discussed. The present chapter attempts to highlight how the use of organic and inorganic salts as alternative postharvest disease management technologies has developed from the laboratory to the market.

Due to well-known nutraceutical properties, pomegranate (Punica granatum L.) cultivation is recently increasing in various areas of the world including Italy. Fungal diseases are the major causes of postharvest yield and economic losses. Most of the fungi infect pomegranates in the field during the blooming stage remaining latent until fruit ripening, others infect fruit during harvest and postharvest handling through rind injuries. Main postharvest fungal diseases of pomegranates are gray and blue molds caused by Botrytis spp. and Penicillium spp., respectively, black heart and black spot due to Alternaria spp., anthracnose related to species ascribable to Colletotrichum genus, and Coniella rot, due to Coniella granati. Few fungicides are allowed for pre- and postharvest treatments, making it extremely difficult to control fungal infections. In this scenario, especially in organic fruit production, alternative control means may be a desirable solution to reduce pomegranate losses during the production chain. This chapter focuses on the most important postharvest diseases of pomegranates and possible strategies and means to reduce spoilage.
