Interpretive Summary: Strawberry plugs are rapidly replacing fresh-dug bare-root and cold-stored frigo plants as transplants for strawberry fruit (Fragaria ananassa) production worldwide. Plugs have many advantages over these other types of propagules. They are grown in controlled environments (greenhouses, tunnels) in less time than field produced bare-root transplants, and are not exposed to soilborne pathogens. Plugs afford greater grower control of transplanting dates, provide mechanical transplanting opportunities and allow improved water management for transplant establishment relative to fresh bare-root plants. New uses for plugs have been identified in recent years; for example, photoperiod and temperature conditioned plugs flower and fruit earlier than traditional transplants and plugs have been used for programmed greenhouse production. Tray plants have superior cold storage characteristics relative to bare-root, waiting-bed transplants. Both fresh and frozen plugs are used in a number of indoor and outdoor growing conditions and cultural systems. This technology and its economics are examined for applications that are rapidly replacing traditional matted-row culture and dormant and fresh-dug plant transplant systems in many parts of the world.
