dc.description.abstract Xanthomonas gardneri is the dominant bacterial spot pathogen affecting tomato production in Southwestern Ontario. There are no effective chemical controls for bacterial spot, so the potential for sanitation and host resistance management was investigated. Pathogen transmission in the plug trailer and transplanter were evaluated to gauge the potential impact of sanitation procedures, and differences in foliar and fruit symptoms of nine commercial cultivars were assessed to gauge existing host resistance. The pathogen moved 122 cm within the trailer, less when plug trays were dipped in water instead of irrigated. The transplanter transmitted the pathogen seedling to seedling but was not as impactful as the environment in field trials. There was no correlation between the incidence or severity of foliar and fruit symptoms in the commercial cultivars tested. Sanitation of the trailer and dip watering are recommended, as is inclusion of fruit symptom observations to select resistant cultivars. en_US
