Technical Abstract: Fungicide application to fruits after harvest has been increasingly problematic due to the development of pathogen resistance to many key fungicides and restrictions on their use. Public pressure for pesticide-free food resulted in the voluntary action of rejecting fruit treated with any synthetic fungicide after harvest by many major food retailers in Europe. Biological control of postharvest decays (BCPD) of fruit with bacteria and yeasts naturally occurring on fruit surfaces has emerged as an effective alternative to synthetic fungicides during the past two decades. Development of the BCPD is a complex process involving a variety of steps related to the discovery of the antagonists and testing efficacy, and safety of the final products. Currently, there are seven biocontrol products registered in various countries in the United States, Europe, Israel, and South Africa. Additional insights are presented into the practical aspects of the development and commercial use of BCPD in order to better understand the flexibility, potential, and limitations of this system. Also, future directions and challenges for the expansion of BCPD to different commodities and diseases are described.
