Progress on postharvest biocontrol has been accomplished in the last 20 years, but biocontrol agents have much more unrealized potential. A better knowledge of antagonist modes of action, screening of additional microorganisms, improvements in biofungicide formulation, and the ecology of antagonists on fruits and vegetables will help in the design of better application strategies and ensure more reliable disease control. Land grant and U.S. Department of Agriculture research should increase their focus on practical implementation of biocontrol agents in integrated programs to reduce the chemical load on postharvest commodities. Setting up a postharvest bio-control network like the Canadian network can provide a dedicated focus on discovery, development, and adoption.
