TitleInhibition of post-harvest pathogen gray mold (Botrytis cinerea) on strawberry (Fragaria ananassa) with application of thyme (Thymus vulgaris) essential oil
DescriptionFruit and vegetable losses in the United States result in significant food waste and billions of dollars in lost revenue, with a major portion of these losses occurring between harvest and distribution. Postharvest losses due to improper handling, storage and disease are among the most prominent. Botrytis cinerea, commonly called grey mold, is a latent necrotrophic fungus responsible for disease observed in over 200 plant species and can infect many plant parts such as stems, leaves, and fruit. In strawberry fruit (Fragaria ananassa), B. cinerea is a major pathogen and has been shown to cause total crop loss and significantly reduce shelf-life for this fresh high value product. Due to the antimicrobial resistance of fungal isolates, including B. cinerea, many producers, distributors, and even consumers are looking towards integrated pest management (IPM) strategies to mitigate their losses and extend product shelf-life. In this dissertation, we use thyme essential oil, which has demonstrated significant antimicrobial activities, to address and mitigate these losses in postharvest application on strawberry caused by grey mold.
