Microbial Control of Postharvest Diseases of Fruits, Vegetables, Roots, and Tubers

Abstract

Postharvest diseases cause considerable losses to harvested fruits, vegetables, roots, and tubers during transportation from farmers’ field to market and in storage. Synthetic fungicides are the primary means to control postharvest diseases. However, microbial control has emerged as one of the most promising alternatives to chemical fungicides. Several microbial agents have been widely investigated for use on different postharvest pathogens. The efficacy of the microbial antagonist(s) can be enhanced if they are used with low doses of fungicides, salt additives, and plant products. At the international level, different microbial antagonists such as Candida sake, Candida oleophila, Cryptococcus laurentii, and Debaryomyces hansenii are being used. Biocontrol products such as Aspire, BioSave, and Shemer have also been developed and registered. Although the results of this technology are encouraging, the formulation and application methods are key issues for the efficacy and successful outcome of the commercial product.
