A comprehensive survey of plant pathogen populations (measured by DNA Multiscans) in irrigation water leachate and/or runoff from the range of Ontario flower and vegetable greenhouses and container nurseries was conducted to help assess the level of risk involved in operations switching to recirculating systems. The ability of several bioremediation technologies to remove plant pathogens from recycled irrigation water (e.g. constructed wetlands, woodchip biofilters) was evaluated as well as the effectiveness of current plant pathogen disinfection systems.
