Control of pathogenic, disease causing microbes is especially critical in vegetable production systems, where the product is often subject to minimal processing before consumption. Hydroponic controlled environment production systems such as greenhouses and indoor farms that employ soilless cultivation with liquid nutrient distributed through fertigation systems have great potential for microbial control, while also providing a conduit for distribution of contaminating pathogens throughout the system. The proposed work aims to refine and implement rapid culture-independent monitoring for controlled environment vegetable production systems, with capability to track both crop disease causing organisms and food borne human pathogens. Widespread adoption of such a monitoring program by Ontario vegetable growers would contribute to more accurate and efficient crop disease and food safety control, resulting in increased yield and quality, reduction of waste, and improved food safety management.
