Phytopathogen-induced postharvest fruit diseases can result in losses of up to 50 % of the world’s total production. The impact on the use of conventional synthetic fungicides on human health and eco-toxicological risk has raised concern all over the world and strategies have been made to limit their use in disease management. The development of various antagonistic microbes as potential bio-control agents has increased due to the need for sustainable agriculture and climate change arising globally. Yeast, a unicellular fungus, is a good substitute for synthetic chemicals and it could grow in various ecological niches. Commercially, yeast and its products are used in the food industry, medicine, and biotechnological research, but it can also provide a range of bio-controlling and growth-promoting properties for plants. Yeast is harnessed as a biocontrol agent as they are known for host surface colonization, host resistance induction, production of antifungal compounds, no production of toxic antibiotics as other antagonists and is considered safe for the final food product. Hence, they are extensively harnessed as a potential antagonist in efficiently managing the post-harvest diseases of fruit throughout the world. Their application to fruit postharvest diseases enables a sustainable substitute for synthetic fungicides, enhancing food safety and prolonging shelf life. This review article focuses on the mode of action and their role in post-harvest protection of fruits.
